Study of bounds on non-equilibrium fluctuations for asymmetrically driven quantum Otto engine
Sandipan Mohanta, Madhumita Saha, B. Prasanna Venkatesh +1
For a four-stroke asymmetrically driven quantum Otto engine with working medium modeled by a single qubit, we study the bounds on non-equilibrium fluctuations of work and heat. We…
Quantum Performance of Thermal Machines over Many Cycles
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +1
The performance of quantum heat engines is generally based on the analysis of a single cycle. We challenge this approach by showing that the total work performed by a quantum engin…
Emergent Universality in Nonequilibrium Processes of Critical Systems
Danh-Tai Hoang, B. Prasanna Venkatesh, Seungju Han +3
We examine the Jarzynski equality for a quenching process across the critical point of second-order phase transitions, where absolute irreversibility and the effect of finite-sampl…
Quantum fluctuation theorems and generalized measurements during the force protocol
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +2
Generalized measurements of an observable performed on a quantum system during a force protocol are investigated and conditions that guarantee the validity of the Jarzynski equalit…
Transient quantum fluctuation theorems and generalized measurements
B. Prasanna Venkatesh, Gentaro Watanabe, Peter Talkner
The transient quantum fluctuation theorems of Crooks and Jarzynski restrict and relate the statistics of work performed in forward and backward forcing protocols. So far these theo…
