,The Role of?Initial Coherence in?the?Phase-Space Entropy Production Rate,cess. In this Chapter, we consider the standard scenario of open quantum systems, where a system irreversibly interacts with an external environment. We show that the standard approach, based on von Neumann entropy, can be replaced by a phase-space formulation of the problem. In particular, we focus

,How Small Can Maxwell’s Demon Be?,odes. Without specifying the actual implementation of external feedback loops, one can only partially quantify the additional contributions to entropy production. This is different in autonomously operating systems with internal feedback. Traditional (bipartite) autonomous systems can be divided int

,Many-Body Thermal States on?a?Quantum Computer: A Variational Approach,plexity of the Hilbert space they live in. Quantum computers may have the potential to effectively simulate quantum systems, provided that the many-body state under scrutiny can be faithfully prepared via an efficient algorithm. With this aim, we present a hybrid quantum–classical variational quantu

,Virtual Potential Created by a Feedback Loop: Taming the Feedback Demon to?Explore Stochastic Therms. In particular double-well potentials have applications in information processing, such as the demonstration of Landauer’s principle. In this chapter, we detail the implementation of a feedback loop for an underdamped system, in order to build a tunable virtual double-well potential. This feedback

Symmetry, Chirality and Unidirectional Motion,tum mechanical aspects, we discuss Hund’s paradox–namely why, although the complete Hamiltonian of a molecule is parity-invariant, broken symmetry enantiomeric states appear and can be frequently isolated as macroscopic samples. A first approach is based on the existence of a potential energy curve

Asymmetric Energy Barriers in Unidirectional Molecule-Rotors,molecule-rotors. For the rotation to be unidirectional, these barriers must be asymmetric. We study two systems. The first is an acetylene molecule which rotates on a basin formed by a Pd trimer on a chiral PdGa surface. The second are DMBI derivatives on the (111) surface of gold, which rotate afte
