Frequency-dependent criticality in optical properties of the Drude metals, including plasmas and seawater
Bikram Keshari Behera, Rhitabrata Bhattacharyya, Shyamal Biswas
We have analytically determined attenuation constant, phase constant, and reflectivity of Drude metals over the entire frequency range () for an incident electromagneti…

Revisiting the integral form of Gauss' law for a generic case of electrodynamics with arbitrarily moving Gaussian surface
Shyamal Biswas
We have re-examined the integral form of Gauss' law for arbitrarily moving charges inside and outside an arbitrarily expanding (or contracting) and deforming Gaussian surface. We h…

Scaling theory for the collapse of a trapped Bose gas in a synthetic magnetic field: a critical study at the condensation point
Bikram Keshari Behera, Shyamal Biswas
We have analytically explored both the zero temperature and the finite temperature scaling theory for the collapse of an attractively interacting 3-D harmonically trapped Bose gas…
