Quantum Lunch

Work optimization from linear response theory

Thiago Acconcia
Universidade Estadual de Campinas (Unicamp)

LOCATION CHANGE: All real processes occur in finite-time and unavoidably dissipate energy. Thus, a ubiquitous goal in thermodynamics is to optimize finite-time processes by minimizing the dissipated or excess work. In this seminar, we will discuss the derivation and application of a degenerate family of optimal protocol that minimizes the production of excess work for both, classical and quantum systems. We will illustrate our findings analytically and numerically for the parametric harmonic oscillator and a spin-½ system. As a generalization of our findings we will then treat optimal heat engines within linear response theory. As a main result, we will propose a novel description of Microcanonical Szilard Engines.

Host: Sebastian Deffner
