Entanglement Evolution of Noisy Quantum Systems: Master Equation-TFD Solutions
Urjjarani Patel, KVS Shiv Chaitanya
In this paper, Thermofield Dynamics (TFD) is applied to map a quantum optics nonlinear master equation into a Schrodinger-like equation for any arbitrary initial condition. This fo…
Negative refractive index, Perfect Lens and Cesàro convergence
Yuganand Nellambakam, K. V. S. Shiv Chaitanya
In this letter, we show that the restoration of evanescent wave in perfect lens obeys a new kind of convergence known as Cesaro convergence. Cesaro convergence allows us to extend…
Relativistic Potentials with Rational Extensions
K. Haritha, K. V. S. Shiv Chaitanya
In this paper, we construct isospectral Hamiltonians without shape invariant potentials for the relativistic quantum mechanical potentials such as the Dirac Oscillator and Hydrogen…
Quantum Hydrodynamics: Kirchhoff Equations
K. V. S. Shiv Chaitanya
In this paper, we show that the Kirchhoff equations are derived from the Schrödinger equation by assuming the wave function to be a polynomial like solution. These Kirchhoff equati…
Quantum entanglement in coupled lossy waveguides using SU(2) and SU(1,1) Thermo-algebras
M. Naveen Kumar, K. V. S. Shiv Chaitanya, Bindu A. Bambah
In this paper, the master equation for the coupled lossy waveguides is solved using the thermofield dynamics(TFD) formalism. This formalism allows the use of the underlying symmetr…
Baryon Asymmetry, Inflation and Squeezed States
Bindu A. Bambah, K. V. S. Shiv Chaitanya, C. Mukku
We use the general formalism of squeezed rotated states to calculate baryon asymmetry in the wake of inflation through parametric amplification. We base our analysis on a B and CP…
