    • Efficiency fluctuations in a quantum battery charged by a repeated interaction process 
      Barra de la Guarda, Felipe (MDPI, 2022)
      A repeated interaction process assisted by auxiliary thermal systems charges a quantum battery. The charging energy is supplied by switching on and off the interaction between the battery and the thermal systems. The charged ...
    • Quantum batteries at the verge of a phase transition 
      Barra de la Guarda, Felipe; Hovhannisyan, Karen V.; Imparato, Alberto (IOP, 2022)
      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 quantum device that is in thermal equilibrium, ...
