    • Magnetic engine for the single-particle Landau problem 
      Peña, Francisco J.; González, Alejandro; Núñez Vásquez, Álvaro; Orellana, Pedro A.; Rojas, René G.; Vargas, Patricio (MDPI, 2017)
      We study the effect of the degeneracy factor in the energy levels of the well-known Landau problem for a magnetic engine. The scheme of the cycle is composed of two adiabatic processes and two isomagnetic processes, driven ...
    • Magnetic Otto engine for an electron in a quantum dot: Classical and quantum approach 
      Peña, Francisco J.; Negrete, Oscar; Barrios, Gabriel Alvarado; Zambrano, David; González, Alejandro; Nunez, Alvaro S.; Orellana, Pedro A.; Vargas, Patricio (MDPI AG, 2019)
      We studied the performance of classical and quantum magnetic Otto cycle with a working substance composed of a single quantum dot using the Fock-Darwin model with the inclusion of the Zeeman interaction. Modulating an ...
    • 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, ...
