El próximo jueves 2 de julio, el Dr. Felipe Barra, destacado investigador en Termodinámica Cuántica y profesor asociado de la Universidad de Chile, dictará el coloquio “Quantum Thermodynamics and Information: Maxwell’s Demon in a Quantum Thermoelectric Engine” a las 14:30 horas en la Sala 208 del Instituto de Física, Edificio de Ciencias, Campus Curauma, PUCV.
Compartimos el resumen de la presentación:
Can information drive a current against a bias? This talk introduces a quantum thermoelectric engine where part of the system acts as an autonomous Maxwell’s demon.
The laws of thermodynamics are deeply connected with notions of information. Quantum thermodynamics explores this connection in systems where coherence, entanglement, and measurement backaction can affect energy and particle transport. In this talk, I will introduce some central ideas of the field through a concrete example: a multipartite quantum system operating as a thermoelectric engine. The device can be interpreted as an autonomous Maxwell’s demon, where one part of the system monitors another and helps drive a particle current against a chemical-potential bias. I will discuss how quantum coherences and correlations appear in the steady state, and how coupling to a dephasing environment induces a transition toward a more classical transport regime.
Extendemos la invitación a la comunidad del Instituto de Física y público interesado a participar de este coloquio.
