A measure for adiabatic contributions to quantum transitions

R. Pant, P. K. Verma, C. Rangi +4

We construct a measure for the adiabatic contribution to quantum transitions in an arbitrary basis, tackling the generic complex case where dynamics is only partially adiabatic, si…

Steiljes electrostatic model with imaginary charges resolves wave-particle duality

K V S Shiv Chaitanya, V Srinivasan

In this paper, we show that the quantum bound state problems are mapped to point vortices with the identical circulation or strength using the Steiljes electrostatic model with…

Light-matter interaction and Bose-Einstein condensation of light

Vivek M. Vyas, Prasanta K. Panigrahi, V. Srinivasan

The atom - electromagnetic field interaction is studied in the Dicke model, wherein a single field mode is interacting with a collection of two level atoms at thermal equilibrium.…

A gauge theory of massive spin one particles

Vivek M. Vyas, V. Srinivasan

An Abelian gauge theory describing dynamics of massive spin one bosons is constructed. This is achieved by appending to the Maxwell action, a gauge invariant mass term. The theory…

Separability Criterion for Multi-Mode Gaussian States

K. V. S. Shiv Chaitanya, Sibasish Ghosh, V. Srinivasan

In this paper, we give Separability criterion for the multi-mode Gaussian states using the Marchenko-Pastur theorem. We show that the Marchenko-Pastur theorem from random matrix th…

Some results on topological currents in field theory

Vivek M. Vyas, V. Srinivasan, Prasanta K. Panigrahi

A few exact results concerning topological currents in field theories are obtained. It is generally shown that, a topological charge can not generate any kind of symmetry transform…
