We study bounds on ratios of fluctuations in steady-state time-reversal energy conversion
devices. In the linear response regime, we prove that the relative fluctuations (precision) of …

It is investigated whether non-Markovianity, ie, the memory effects resulting from the
coupling of the system to its environment, can be beneficial for the performance of quantum …

We study fluctuations in many-body quantum heat engines operating in the presence of
collective system-bath interactions. We show that collective effects in open quantum systems …

Unlike classical systems, a measurement performed on a quantum system always alters its
state. In this work, the impacts of two diagnostic schemes to determine the performance of …

Fluctuations of thermodynamic quantities become non-negligible and play an important role
when the system size is small. We develop finite-time thermodynamics of fluctuations in …

For quantum Otto engine driven quasistatically, we provide exact full statistics of heat and
work for a class of working fluids that follow a scale-invariant energy eigenspectra under …

We use Floquet formalism to study fluctuations in periodically modulated continuous
quantum thermal machines. We present a generic theory for such machines, followed by …

We study universal aspects of fluctuations in an ensemble of noninteracting continuous
quantum thermal machines in the steady-state limit, beyond linear response. Considering an …

For a generic class of machines with broken time-reversal symmetry we show that in the
linear response regime the relative fluctuation of the sum of output currents for time-forward …

We study the ratio between the variances of work output and heat input, η (2), for a class of
four-stroke heat engines, which covers various typical cycles. Recent studies on the upper …
