Quantum batteries at the verge of a phase transition
Felipe Barra, Karen V. Hovhannisyan, Alberto Imparato
Starting from the observation that the reduced state of a system strongly coupled to a bath is, in general, an athermal state, we introduce and study a cyclic battery-charger quant…
Thermometric machine for ultraprecise thermometry of low temperatures
Ivan Henao, Karen V. Hovhannisyan, Raam Uzdin
Thermal equilibrium states are exponentially hard to distinguish at very low temperatures, making equilibrium quantum thermometry in this regime a formidable task. We present a the…
Energy conservation and fluctuation theorem are incompatible for quantum work
Karen V. Hovhannisyan, Alberto Imparato
Characterizing fluctuations of work in coherent quantum systems is notoriously problematic. Here we reveal the ultimate source of the problem by proving that () energ…
