Quantum Jarzynski Equality with multiple measurement and feedback for isolated system
Shubhashis Rana, Sourabh Lahiri, A. M. Jayannavar
In this paper, we derive the Jarzynski equality (JE) for an isolated quantum system in three different cases: (i) the full evolution is unitary with no intermediate measurements, (…
The effect of confinement on stochastic resonance in continuous bistable systems
Shubhashis Rana, Sourabh Lahiri, A. M. Jayannavar
Using the input energy per cycle as a quantifier of stochastic resonance (SR), we show that SR is observed in superharmonic (hard) potentials. However, it is not observed in subhar…
Fluctuation theorems in presence of information gain and feedback
Sourabh Lahiri, Shubhashis Rana, A. M. Jayannavar
In this study, we rederive the fluctuation theorems in presence of feedback, by assuming the known Jarzynski equality and detailed fluctuation theorems. We first reproduce the alre…
Conserved Correlation in PT -symmetric Systems: Scattering and Bound States
Kumar Abhinav, Arun Jayannavar, P. K. Panigrahi
For one-dimensional PT -symmetric systems, it is observed that the non-local product obtained from the continuity equation can be interpreted as a conserved corre- lation function.…
