Quasiprobability distribution for heat fluctuations in the quantum regime
The standard approach to deriving fluctuation theorems fails to capture the effect of quantum
correlation and coherence in the initial state of the system. Here, we overcome this difficulty …

Work statistics, quantum signatures, and enhanced work extraction in quadratic fermionic models
In quadratic fermionic models, we determine a quantum correction to the work statistics after
both a sudden quench and a time-dependent driving. Such a correction lies in the …
