Proof of quantum mechanical H-theorem beyond binary collisions in quantum gases
Bandita Das, Shyamal Biswas
We have proved the quantum mechanical H-theorem for dilute Bose and Fermi gases by generalizing the quantum statistical Boltzmann equation for all possible many-body elastic collis…
Energy fluctuation and discontinuity of specific heat
Shyamal Biswas, Joydip Mitra, Saugata Bhattacharyya
Specific heat per particle () of an ideal gas, in many occasions, is interpreted as energy fluctuation per particle () of the ideal gas through the relation: $\t…
Casimir effect for a Bose-Einstein condensate inside a cylindrical tube
Shyamal Biswas, Saugata Bhattacharyya, Amit Agarwal
We explore Casimir effect on an interacting Bose-Einstein condensate (BEC) inside a cylindrical tube. The Casimir force for the confined BEC comprises of (i) a mean-field part aris…
A complete theory for the magnetism of an ideal gas of electrons
Shyamal Biswas, Swati Sen, Debnarayan Jana
We have explored Pauli paramagnetism, Landau diamagnetism and de Haas-van Alphen effect in a single framework, and unified these three effects for all temperatures as well as for a…
Proposed fitting function for the critical Casimir force on He film below the point
Shyamal Biswas
We have extended the mean field calculation of Zandi et al [1] and have obtained an approximate mathematical expression for the Casimir scaling function, which if extrapolated to t…
Casimir force on interacting Bose-Einstein condensate
Shyamal Biswas, J. K. Bhattacharjee, Dwipesh Majumder +2
We have presented an analytic theory for the Casimir force on a Bose-Einstein condensate (BEC) which is confined between two parallel plates. We have considered Dirichlet boundary…
