HELP!

We have been “fenced in” to our building since 1999 when some bricks fell off the façade. The ~2 M$ fix to the roof and bricks began this summer. After a delay caused by unexpected events, the brick work has resumed. We expect the roof work will resume shortly.

New faculty

Meigan Aronson, experimental condensed matter physics, joined us as Professor of Physics in January 2007 on a joint appointment with Brookhaven National Laboratory.

Meigan’s group studies magnetism and magnetic phase transitions with neutron scattering, magnetic, thermal, and electrical transport measurements. Current projects include the explication of the critical phenomena which accompany phase transitions occurring at zero temperature, where order is stabilized not by reducing temperature, but by tuning an external variable such as pressure, composition, or magnetic field. The fully quantum mechanical modes which accompany the zero temperature phase transition result in unusual properties near the quantum critical point, and often lead to secondary instabilities such as magnetically mediated superconductivity or even more exotic collective states. A second project studies the magnetic and electronic structure of magnetic nanoparticles, where the combination of particle shape, spatial confinement, and novel extended structures can lead to behaviors which are impossible for bulk magnets. For instance, it is possible to modify both the strength and the spatial variation of the internal magnetic field in the nanoparticlesusing chemical modulation, creating new hybrid systems with high degrees of crystalline perfection. Thus, the dynamics and stability of the nanoparticle moment can be controlled, of particular interest if the particles are assembled into extended structures.

Alan Calder, nuclear/computational astrophysics, left a Research Scientist position at the University of Chicago to come to Stony Brook in February 2007 as a Senior Research Scientist. He became an Assistant Professor in Sept. 2007 as part of the NYCCS cluster hire in supercomputational science.

Alan works on modeling astrophysical phenomena on large-scale computers. He has contributed to a variety of problems, including core collapse and thermonuclear (type Ia) supernovae, merging neutron stars, and classical novae, and he studies the basic physics of these problems as well. He is interested in verification (solve the equations right)and validation (solve the right equations) of numerical methods and simulations.

New faculty

Derek Teaney, Nuclear Theory,joined us as Assistant Professor in Sept. 2007 on a joint appointment with the RIKEN BNL Research Center. At Arkansas State University he received the DOE OJI Award.

Derek’s chief interests are the kinetics of high temperature gauge theories and the phenomenology of heavy ion reactions at RHIC (now) and the LHC (future). He is computing transport quantities of interest to heavy ion physicists using methods of string theory and perturbation theory and exploring new ways to challenge these ideas with heavy ion data.

New faculty

Matt Dawber, experimental condensed matter physics, will join us as Assistant Professor in January 2008. He is currently a postdoc at the University of Geneva, Switzerland.

Ferroelectric materials possess high degrees of functionality, with highly exploitable electrical, mechanical and optical properties. Matt’s research looks at how the ferroelectric properties of these materials can be modified and exploited by modification of the material on the nanoscalelevel. This requires advanced deposition and characterization techniques to probe ferroelectric phenomena on the nanoscale. Investigation of different effects requires a multi-pronged experimental approach, using x-ray, scanning probe and electrical measurements, to relate the system’s macroscopic behaviour to the underlying microscopic physics.

New faculty

Artificially layered ferroelectric structures, with layers only a few atoms thick, can be produced using advanced thin film deposition techniques. An interfacially driven form of improper ferroelectricity, in which rotational and polar modes couple at interfaces, was revealed by linking a number of experimental observations to first principles simulations. Now the driving force is understood we can go to the next step: to produce new multifunctional materials whose behavior is driven by this interaction.

Improper ferroelectricity in artificially layered superlattices

• Development and application of linear-scaling electronic structure methods

• Characterization of structure at the atomic and electronic level of complex systems such as water: Ab-initio molecular dynamic simulations showed how the structure and dynamics of liquid water is directly related to the quantum-mechanical nature of the hydrogen bonds that join the molecules together.

• Study of the links between structure and functionality in enzymes and in the design and characterization of nano-materials such as nanowires, including electronic transport studies.

Marivi Fernandez-Serra will join us as Assistant Professor in Jan. 2008 after completing a

postdoc in Lyons at CECAM (European Center for Atomic and Molecular Simulations). She is

part of the NYCCS cluster hire.

The bequest by the Simons Foundation sponsors special lecturers to visit the Department or YITP for about a week (or longer) and give a series of talks. Each lecturer is available for discussions and interactions with students and faculty.

Nikita Nekrasov of the Institut des Hautes Etudes Scientifiques in France gave six lectures in March 2007 in the YITP on Minimal Models of Gauge and String Theory.

Pierre Meystre, Head of the Department of Physics and Regents Professor of Optical Sciences at the University of Arizona will be a Simons Lecturer in the Department during 12-16 November 2007. He will give two specialized seminars the colloquium on 13 November, and a Worlds of Physics pubic lecture on 16 November. Stay tuned for his detailed program of talks.

More Simons lecturers are anticipated for the Spring 2008 and following semesters.

To give students a flavor for the research opportunities that the Department offers, I asked each research area to prepare summary slides. Disclaimer: Any errors in description are mine. The speed of presentation is unavoidable. Hold on!

I attempt to organize the presentation from largest to the smallest scales, but even this has problems: unity of physics.

But first we must realize that significant grant funding is needed to support our research program.

Nuclear Theory I:Ismail Zahed computed a

number of phyiscal quantities with AdS/CFT. He also found time for calculations with Kevin Dusling on the dilepton mass spectrum in a heavy ion collision.

Jac Verbaarschot formulated precisely when and where Lattice QCD calculations are possible at finite baryon density. Alternating signs make Monte Carlo calculations quite hard.

Misha Lublinsky, with Alex Covner and Urs Wiedemannstudied the partonic properties of hadrons when boosted to very high velocities.

Nuclear Theory II:

Derek Teaney computed properties of heavy quarks which are confronted with data measured by the Stony Brook Phenix Group.

Shu Lin and Edward Shuryak computed the stress tensor associated with a static dipole using methods from String Theory. This is a starting point for discussing screening in plasma.

Tom Kuo and (former) students Achem Schwenk, Scott Bogner, Jason Holt, and Jeremy Holt developed a renormalization group method to determine low momentum nuclear interaction. It provides a good basis for recent shell model calculations.

On June 12, 2007, DØ submitted paper announcing discovery of the first hadron containing a quark from each of the three generations: Ξb = (bsd).

Ξb−→ J/ψ Ξ− ; J/ψ → μ+ μ−; Ξ− → Λ π− ; Λ → p π−

Predicted: M(Ξb−) = 5805.7 ± 8.1 MeV

Evidence for single (weak interaction) top quark production

All previous top quark studies involved t t pair production by Strong interaction (σ=7 pb). Weak production of single top (σ=2.9 pb) expected but backgrounds are large (only 1 W in final state)

Why is the weak process >40% of the strong process? Measurement even higher.

Use 3 multivariate techniques (e.g. neural networks) with 24 event shape variables, trained on signal and bknd.24 NNs (e or μ; 2,3,or 4 jets;1or 2 b-jet tags; 2 diagrams).Train network on signal and background simulated events:

Signal NN tends to 1 and background NN tends towards 0.

Signal NN output

Bknd NN

After cut on NN, net excess over background seen σ (p p→1 top) = 4.9 ± 1.4 pb (3.4σ)

Efforts of C. N. Yang, B.M. McCoy and V.E. Korepin in Statistical Mechanics were emphasized in the Solvay conference: BETHE ANSATZ: 75 YEARS LATER.Corresponding contributions are included in the proceedings:C. N. Yang and M. L. Ge, Bethe's Hypothesis, Int. J. Mod. Phys. 20, 2223‐2225 (2006).V.E. Korepin and O.I. Patu ' From Bethe Solution to Open Problems'K. Fabricius, B. M. McCoy The Eight Vertex Model.  New results

Among other results one should mention the following:

V.E. Korepin continued his work on quantum computation. Entanglement is a resource for quantum control. A good measure of entanglement is entropy of a subsystem. Important example is a spin chain with unique ground state. Von Neumann entropy of the whole ground state is zero, but a part of the ground state [a block of spins] can have some entropy. It measures the entanglement of the block with the rest of the ground state. Important question is scaling of the entropy with the size of the block. Korepin wrote several papers on the subject with a former graduate student F. Franchini and former PostDoc B.‐Q. Jin. It was established that for gapless Hamiltonians entropy increases logarithmically with the size, but for gap‐full it saturates [reaches the limit].

Korepin also worked on quantum algorithms. Together with a graduate student [Ying Xu] he found a way to accelerate quantum search.

V.E. Korepin together with a student [Ovidiu I. Patu] and Prof Averin worked on fractional statistics.  Correlations functions of one‐dimensional Lieb‐Liniger anyons were evaluated.

Prof. Shrock has continued his research in statistical mechanics (together with quantum field theory).  He studies properties of the Potts model, which is a generalization of the Ising model in which the spins at each site can take on q values rather than just 2, as in the Isingmodel. He has performed exact calculations of the partition function and thermodynamic quantities of this model for certain systemsand has studied analytic properties in the temperature and q. The Potts model partition function is equivalent to a function of central interest in mathematical graph theory, the Tutte polynomial. One aspect of this work is the study of the zeros of the partition function and certain curves onto which they merge in the limit of infinite lattice size. With his former thesis student, S.‐C. Chang, Shrock haspublished or submitted three papers on this during the past year. Shrock is also completing a paper with Prof. McCoy on a related study for the q = 2 Ising case, including also a magnetic field.

Goldman’s group has fabricated electron interferometers operating in high magnetic fields and ultra-low temperatures. An atomic force microscope (AFM) image of a device is shown in (a). The electrons are constrained to move in a 2D plane, 320 nm below the semiconductor surface. Four gold gates are used to control the device. Experiments show characteristic quantum interference patterns for both electrons and fractionally-charged “anyon” quasiparticles. An Aharonov-Bohm “superperiod” corresponding to more than the fundamental flux quantum h/e, was reported for the first time.

Peter Stephens's group works in materials physics to understand the behavior of solids via their atomic structure, especially in cases where that structure is challenging to reveal. In collaboration with chemists at the University of Utah, they have been studying magnets made of metal atoms bonded together by organic molecules. Among many other materials they have studied, this one was so surprising and interesting that it got the cover story of prestigious Angewandte Chemie.

Phase transition in films of VO2

Prof. M. Gurvitch studies a semiconductor-to-metal hysteretic

phase transition which takes place as a function of temperature in films of Vanadium Dioxide (VO2). Many

properties of this remarkable material change dramatically in the transition, including electrical resistivity which changes by a factor of about 2000.
