EXPERIMENTAL MATERIAL SCIENCE GROUP
Dr. Mahavir Singh
Dr. Nainjeet Singh Negi
Dr. Nagesh Thakur
Dr. Vir Singh Rangra
Experimental group in Physics Department is currently working on various
multifunctional materials such as Nanomaterials, Ferrites, multiferroic, ferroelectric,
chalcogenide glasses and shock wave induced synthesis of newer materials.
Ferrites, multiferroic, ferroelectrics, nanostructural materials and
chalcogenide glasses
Complex perovskite oxides exhibit a rich spectrum of properties including magnetism,
ferroelectricity, multiferroic properties, strong correlated electron behaviour and
magnetoresistance, which have been a great interest of research in recent years
� In nano ferrites, there exist the possibility of enhancement of surface based properties
like magnetic and electrical. We have widely studied Ni-Zn, Mn-Zn and Mg-Mn
ferrites
� Natural multiferroic single phase components are rare and their magnetoelectric
responses are either relatively weak or occurs at temperatures too low for practical
applications. In contrast, multiferroic composites which incorporate ferroelectric and
ferri-/ferromagnetic phases, typically yield giant magnetoelectric coupling response
above room temperature which makes them area of research for technological
applications. We have studied BiFeO3 and Fe doped PbTiO3
� Miniaturization of components is highly required in next generation of these devices.
Therefore deposition of nanostructured ferrolectric thin films is one ways for
miniaturizing components. Very little has been reported so far on development of
nanostructural ferroelectric thin films. Fe doped (Pb, Sr)TiO3 nanostructured thin
films have been studied in detail.
.
Particle Physics Research Group
The group is working in the frontier areas of neutrino physics viz solar neutrinos, double beta
decay processes and nuclear structure calculations for nuclear astrophysics. The group has
produced some excellent research work as evidenced by research publications in reputed
international research journals. In the next five years, the group will be focusing on various
aspects of neutrino physics including solar and atmospheric neutrinos, lepton mass matrices,
neutrino less double beta decay and nuclear structure and transfer reactions for nuclear
astrophysics. The group is engaged in constraining the neutrino and solar astrophysical
parameters in the light of the latest solar neutrino data from SNO, KamLAND, Super
Kamiokande and other solar neutrino experiment like GNO etc. The group is eagerly awaiting
the data from the forthcoming Borexino experiment, which is expected to start taking data very
soon. The group has embarked upon an ambitious programme to work on the refinement of the
Large Mixing Angle Solution( LMA) and investigate the scope of other subdominant transitions in
the resolution of the solar neutrino problem subject of a worldwide experimental and theoretical
effort. The group is initiating a major programme to constrain the lepton mass matrices from the
solar and atmospheric neutrino data and constrain the multiplicity of unified models beyond the
Standard Model. It is expected that some of the models can be ruled out on the basis of neutrino
phenomenology combined with other particle data.

Nuclear Physics and Astrophysics
The main research interests are focused on the strongly interacting finite and infinite nuclear matter
within the framework of Effective Field Theory (EFT) and Exact Renormalization Group (RG), and EFT
and Density Function (DFT) of Mean filed theory. We are also interested to understand the
stable/unstable color superconducting phases of quark matter in the interior of compact stars. The results
of nuclear models in conjunction with General Relativity can employed to study the Rapid rotation of
compact stars, Cooling of compact stars, Stellar pulsation, Mass accrection onto compact stars, and
Gravity-wave instability in rotating compact stars. This is relevant to experiments that are planned at
nuclear physics facilities and, astrophysically, to the structure of compact stars
OBJECTIVES:
1. Carry out frontline research in the thrust areas at the forefront of scientific activities in
theoretical Nuclear Physics and Astrophysics
2. Develop theoretical and phenomenological expertise and specific tools to analyse and
explain data of ongoing future national and international experimental facilities in nuclear
physics and compact stars.
3. Contribute to the human resource development in theoretical nuclear physics through
training of person in advanced basic science research.

Condensed Matter Research Group
Condensed matter physics group is working in classical fluids, quantum fluids and soft condensed
matter. In classical liquids, we have studied the dynamic and transport properties of LJ fluids, liquid
metals and expanded liquid metals.
Presently, the major work we are carrying out to study the mass dependence of mutual diffusion
in Lennard- Jones fluids by MD simulation and to study the transport properties of LJ fluids in the
presence of wave vector q. In the former case there is no experimental data is available for the mass
dependence of Mutual diffusion. Here we will study the self as well as mutual diffusion by the mean
square displacement method and by integrating the time correlation function relevant to the diffusion
coefficient . The self- diffusion coefficient of respective particle will be calculated from the mean square
displacement of the particle 1 and 2. For this we need the position particles at various times which we
can have from the trajectories of the particle. On the other hand we can also calculate the self diffusion
coefficient of particles 1 and 2 from the velocity auto correlation function ( VACF) using Green Kubo
formula. But for the Mutual diffusion we have to calculate the relative velocity correction function. For
this we need the velocities of two particles at different times. For position and velocities of the
particles. During simulation the temperature of the system will be kept constant and the system will be
left for equilibrated for 20,000 time steps.
The time correlation function has provided a powerful tool for the theoretical prediction of
transport properties. In this approach the transport properties are related to the time integrals of the time
correlation function of appropriate fluxes. The time correlation function may be obtained using Mori
Zwanzig formalism or one may also assume a phenomenological form for the correlation function,
which is then imposed to yield the exact short time expansion, of the function. The Mori- Zwanzig
formalism provides the continued fraction representation for the time correlation function in terms of
memory function. Memory function can be obtained using either a microscopic approach or some
phenomenological arguments. The success of this approach depends on the exact knowledge of the first
frequency sum rules, i.e. moments of the short time expansion of the correlation function.
Expression for the first few non- vanishing moments relevant to the calculation of the diffusion
coefficient, viscosity and thermal conductivity are available in literature. Here, we are interested in
deriving the first few non- vanishing moments of the heat flux correlation function by including the
enthalpy fluctuations in the presence of wave vector q. Expressions obtained so far will be further used
to calculate the thermal conductivity of Lennard Jones fluids.
It will be a first step to study the effect of wave vector on the behaviour of time correlation
function and hence to the thermal conductivity. The same procedure will be used to study the other
properties like viscosity and self diffusion later on.
The third problem is to study the dynamic excitation in electron fluid by using Mori’s memory
function formulism. Here the dynamic density and spin density response function will be expressed in
terms of their corresponding static susceptibilities and memory kernels. An exact microscopic
calculation of the memory kernel is not feasible and we will in the mode coupling approximation. The
formulism will provides us a set of coupled equations to be solved self consistently for the dynamic
excitation spectrum of the electron fluid. This approach will be further extended to the coupled layer
systems.

Particle Physics Research Group
First Year Plan:
It is proposed to subject the Large mixing Angle Solution to deeper scrutiny and Constrain the
neutrino and solar astrophysical parameters in the light of the latest solar neutrino data.
Second Year Plan:
It is proposed to examine the scope for other subdominant transitions, which can coexist with the
dominant LMA transitions in the light of the solar neutrino data . The role of other subdominant
transitions driven by the possible neutrino magnetic moment and the transitions into sterile
neutrinos in the solution of the solar neutrino problem will be examined in detail.
Third Year Plan:
The role of weakly mixed sterile neutrinos in the resolution of the remaining neutrino anomalies
viz. the lack of spectral upturn at low energies and the low Argon production rate in Home stake
contrary to the LMA expectations will be examined.
Fourth Year Plan:
The evidence for time modulations of the solar neutrino flux with the rotation period of the Sun
reported by the Stanford group is expected to crystallize by his time especially because of the
availability of data from the forthcoming solar neutrino experiments especially Borexino. It is
proposed to examine this evidence carefully and construct models to explain these time variations
if found real.
Fifth Year Plan
It is proposed to constrain the neutrino mass matrices in particular and the lepton mass matrices in
general in the light of the vast amount of solar, atmospheric and terrestrial neutrino data. An
unified picture of quark and lepton mixing matrices will be sought which will be used to examine
the phenomenological viability of different classes of Grand Unified models. It is expected that the
study will rule out many of the GUT models found in the literature.
CONDENSED MATTER (THEORY)
In the first year we will derive the expression for the frequency sum rules of heat flux correlation
function and at the same time the MD simulation for the mass dependence will be in progress.
In the second year we will do some analytical calculations for thermal conductivity in the
memory function approach. The numerical calculations will also be done in the same year. MD
simulation will remain in progress side by side. In the third year, we will write the manuscript and send it
for publication.
In the fourth year, we will derive expression for the frequency sum rules of the transverse stress
correlation function. We will derive expression for zeroth, second and fourth sum rules of the transverse
stress auto correlation function. At the same time Mori’s memory function formulism and mode coupling
approximation will be standard for the dynamic excitations in electron fluid.
In the fifth year, we will carry out the analytical calculations for the coefficient of shear
viscosity. The numerical calculations will also be done in the same year. The problem of electron fluid
will remain in progress aside by side.
In the next year we will write the manuscript and send it for publication
