Decohering d-dimensional quantum resistance
Dibyendu Roy, N. Kumar
The Landauer scattering approach to 4-probe resistance is revisited for the case of a d-dimensional disordered resistor in the presence of decoherence. Our treatment is based on an…
Crossover from normal (N) Ohmic subdivision to superconducting (S) equipartition of current in parallel conductors at the N-S transition: Theory
N. Kumar
The recently observed (1) equipartition of current in parallel at and below the Normal-Superconducting (N-S) transition can be understood in terms of a Landau-Ginzburg order-parame…
Supersolid and the non-uniform condensate
N. Kumar
We construct a model of non-uniform condensate having a spatially modulated complex order parameter that makes it kinematically an x-ray solid, i.e., a real mass density wave, but…
Dissipative electron-phonon system photoexcited far from equilibrium
Navinder Singh, Navinder Singh Bathinda, N. Kumar
We derive the steady-state electron distribution function for a semiconductor driven far from equilibrium by the inter-band photoexcitation assumed homogeneous over the nanoscale s…
Decohering quantum statistics: Suppression of BEC
N. Kumar
It is argued that the environment induced decoherence between spatially separated parts of the wavefunction for an open quantum system also classicalizes the quantum statistics whi…
Vogel-Fulcher law of glass viscosity: A new approach
N. Kumar
Starting with an expression, due originally to Einstein, for the shear viscosity \textit{}(\textit{}) of a liquid having a small fraction \textit{}by volume of solid par…
