Fermion localization in higher curvature spacetime
Sayantan Choudhury, Joydip Mitra, Soumitra SenGupta
Fermion localization in a braneworld model in presence of dilaton coupled higher curvature Gauss-Bonnet bulk gravity is discussed. It is shown that the lowest mode of left handed f…
Condensate fraction and critical temperature of interacting Bose gas in anharmonic trap
Sudip Kumar Haldar, Barnali Chakrabarti, Satadal Bhattacharyya +1
By using a correlated many body method and using the realistic van der Waals potential we study several statistical measures like the specific heat, transition temperature and the…
Universal scaling in disordered systems and non-universal exponents
K. K. Bardhan, D. Talukdar, U. N. Nandi +1
The effect of an electric field on conduction in a disordered system is an old but largely unsolved problem. Experiments cover an wide variety of systems - amorphous/doped semicond…
Characterization of kinetic coarsening in a random-field Ising model
Pradipta Kumar Mandal, Suman Sinha
We report a study of nonequilibrium relaxation in a two-dimensional random field Ising model at a nonzero temperature. We attempt to observe the coarsening from a different perspec…
Scaling of NonOhmic Conduction in Strongly Correlated Systems
D. Talukdar, U. N. Nandi, A. Poddar +2
A new scaling formalism is used to analyze nonlinear I-V data in the vicinity of metal-insulator transitions (MIT) in five manganite systems. An exponent, called the nonlinearity e…
Nonlinearity exponents in lightly doped Conducting Polymers
D. Talukdar, U. N. Nandi, K. K. Bardhan +4
The \textit{I-V} characteristics of four conducting polymer systems like doped polypyrrole (PPy), poly 3,4 ethylene dioxythiophene (PEDOT), polydiacetylene (PDA) and polyaniline (P…
Quasi-one dimensional graphite ribbon structures in presence of magnetic field and on-site Coulomb correlation at half-filling
Jayeeta Chowdhury, Shreekantha Sil, S. N. Karmakar +1
We have presented the role of the Coulomb interaction () and the magnetic field () on the ground state properties of the quasi-one dimensional graphite ribbon structure…
Effect of Fibonacci Modulation On Superconductivity
Sanjay Gupta, Shreekantha Sil, Bibhas Bhattacharyya
We have studied finite-sized single band models with short range pairing interactions between electrons in presence of diagonal Fibonacci modulation in one dimension. Two models, n…

We have studied the emission of neutrinos from a rotating hybrid star. We find that the emission is predominantly confined to a very small angle, provided the core of the star is i…
Strangeness, Cosmological Cold Dark Matter and Dark Energy
Sibaji Raha, Shibaji Banerjee, Abhijit Bhattacharyya +5
It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (Cold Dark Matter: CDM) which is non-luminous and a…
