Geometric Finiteness, Holography and Quasinormal Modes for the Warped AdS_3 Black Hole
Kumar S. Gupta, E. Harikumar, Siddhartha Sen +1
We show that there exists a precise kinematical notion of holography for the Euclidean warped black hole. This follows from the fact that the Euclidean warped black…
Turbulent flow in graphene
Kumar S. Gupta, Siddhartha Sen
We demonstrate the possibility of a turbulent flow of electrons in graphene in the hydrodynamic region, by calculating the corresponding turbulent probability density function. Thi…
Effects of Quantum Vacuum Fluctuations of the Electric Field on DNA Condensation
Alfredo Iorio, Samik Sen, Siddhartha Sen
By assuming that not only counter-ions but DNA molecules as well are thermally distributed according to a Boltzmann law, we propose a modified Poisson-Boltzmann equation at the cla…
Scattering in graphene with impurities : A low energy effective theory
Kumar S. Gupta, Andjelo Samsarov, Siddhartha Sen
We analyze the scattering sector of the Hamiltonians for both gapless and gapped graphene in the presence of a charge impurity using the 2D Dirac equation, which is applicable in t…
