Clausius Inequality for Finite Baths Reveals Universal Efficiency Improvements
Philipp Strasberg, María García Díaz, Andreu Riera-Campeny
We study entropy production in nanoscale devices, which are coupled to finite heat baths. This situation is of growing experimental relevance, but most theoretical approaches rely…
How long does it take to implement a projective measurement?
Philipp Strasberg, Kavan Modi, Michalis Skotiniotis
According to the Schrödinger equation, a closed quantum system evolves continuously in time. If it is subject to a measurement however, its state changes randomly and discontinuous…
Quantum systems correlated with a finite bath: nonequilibrium dynamics and thermodynamics
Andreu Riera-Campeny, Anna Sanpera, Philipp Strasberg
Describing open quantum systems far from equilibrium is challenging, in particular when the environment is mesoscopic, when it develops nonequilibrium features during the evolution…
First and Second Law of Quantum Thermodynamics: A Consistent Derivation Based on a Microscopic Definition of Entropy
Philipp Strasberg, Andreas Winter
Deriving the laws of thermodynamics from a microscopic picture is a central quest of statistical mechanics. This tutorial focuses on the derivation of the first and second law for…
