Weak measurement as a tool for studying coherence and quantum correlations in bipartite systems
Indrajith V. S, R. Muthuganesan, R. Sankaranarayanan
In this article, we study quantum coherence of bipartite state from the perspective of weak measurement, which generalizes the notion of coherence relative to measurement. The is b…
Continued functions and critical exponents: Tools for analytical continuation of divergent expressions in phase transition studies
Venkat Abhignan, R. Sankaranarayanan
Resummation methods using continued functions are implemented to converge divergent series appearing in perturbation problems related to continuous phase transitions in field theor…
Casimir interactions from infinite range and dilation symmetry
Venkat Abhignan, R. Sankaranarayanan
The Casimir interaction energy for a class of discrete self-similar configuration of parallel plates is evaluated using existing methods. The similarities to characteristics of an…
Exit dynamics from Morse potential under thermal fluctuations
P Vipin, R Sankaranarayanan
We study the dynamics of a Brownian particle in Morse potential under thermal fluctuations, modeled by Gaussian white noise whose amplitude depends on absolute temperature. Dynamic…
Fidelity based purity and coherence for quantum states
Indrajith V S, R. Muthuganesan, R. Sankaranarayanan
Purity and coherence of a quantum state are recognized as useful resources for various information processing tasks. In this article, we propose a fidelity based valid measure of p…
Role of virial coefficients in chemical reaction
Vipin P, R. Sankaranarayanan
van't Hoff equation relates equilibrium constant of a chemical reaction to temperature . Though the van't Hoff plot ( vs ) is linear, it is nonlinear for certain…
