Concentration of ergotropy in many-body systems
Karen V. Hovhannisyan, Rick P. A. Simon, Janet Anders
Ergotropy -- the maximal amount of unitarily extractable work -- measures the ``charge level'' of quantum batteries. We prove that in large many-body batteries ergotropy exhibits a…
Revising the quantum work fluctuation framework to encompass energy conservation
Giulia Rubino, Karen V. Hovhannisyan, Paul Skrzypczyk
Work is a process-based quantity, and its measurement typically requires interaction with a measuring device multiple times. While classical systems allow for non-invasive and accu…
Correlations enable lossless ergotropy transport
Rick P. A. Simon, Janet Anders, Karen V. Hovhannisyan
"A battery powers a device" can be read as "work stored in the battery is being transported to the device." In quantum batteries, the total amount of stored work can be measured by…
