Robust many-body quantum batteries
Finn Schmolke, Karen Hovhannisyan, Milton Aguilar
Realistic work extraction from many-body quantum batteries must be local. However, only a small fraction of energy eigenstates of a generic many-body system, called scars, can supp…
Ancilla mediated steady-state engineering in open quantum systems
Soham Pal, Karen Hovhannisyan, Omri Porat +3
Engineering the properties of a reservoir and its coupling to a quantum system is a powerful tool for simulating quantum thermodynamic processes and for generating otherwise inacce…
Minimally invasive measurement of work in coherent quantum systems
Cyril Elouard, Karen Hovhannisyan, Giulia Rubino
A central challenge in quantum thermodynamics is to access work fluctuations in coherent processes without distorting the energetics of the unmeasured evolution. In standard two-po…
Autonomous conversion of particle-exchange to quantum self-oscillations
Sofia Sevitz, Federico Cerisola, Karen V. Hovhannisyan +1
Particle-exchange machines utilize electronic transport to continuously transfer heat between fermionic reservoirs. Here, we couple a quantum mechanical resonator to a particle-exc…
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…
