Understanding out-of-equilibrium quantum dynamics is a critical outstanding problem, with key questions regarding characterizing adiabaticity for applications in quantum technologies. We show how the metric-space approach to quantum mechanics naturally characterizes regimes of quantum dynamics and provides an appealingly visual tool for assessing their degree of adiabaticity. Further, the dynamic trajectories of quantum systems in metric space suggest a lack of ergodicity, thus providing a… Expand

Characterizing Adiabaticity in Quantum Many‐Body Systems at Finite Temperature
The quantum adiabatic theorem is fundamental to time dependent quantum systems, but being able to characterize quantitatively an adiabatic evolution in many-body systems can be a challenge. This workExpand
Quantum thermodynamic properties in many-body systems out-of-equilibrium
Relatively small many-body quantum systems are often used as hardware for quantum devices. Most of these devices will operate below the thermal limit where thermodynamics must be treated differentlyExpand
Metrics for Two Electron Random Potential Systems
Metrics have been used to investigate the relationship between wavefunction distances and density distances for families of specific systems. We extend this research to look at random potentials forExpand
Work-distribution quantumness and irreversibility when crossing a quantum phase transition in finite time
The thermodynamic behavior of out-of-equilibrium quantum systems in finite-time dynamics encompasses the description of energy fluctuations, which dictates a series of system's physical properties.Expand


Experimental study of the validity of quantitative conditions in the quantum adiabatic theorem.
The standard criterion for adiabatic evolution experimentally and theoretically is examined, and it is shown that the standard criterion is neither sufficient nor necessary. Expand

Quantum thermodynamics is an emerging research field aiming to extend standard thermodynamics and non-equilibrium statistical physics to ensembles of sizes well below the thermodynamic limit, inExpand
Time Scale for Adiabaticity Breakdown in Driven Many-Body Systems and Orthogonality Catastrophe.
This work shows how the adiabatic theorem can be bridged for a broad natural class of physical systems, namely, many-body systems where a small move in the parameter space induces an orthogonality catastrophe. Expand
Perspective on quantum thermodynamics
Classical thermodynamics is unrivalled in its range of applications and relevance to everyday life. It enables a description of complex systems,made up ofmicroscopic particles, in terms of a smallExpand
Quantum Thermodynamics: A Dynamical Viewpoint
The emergence of the 0-law, I- law, II-law and III-law of thermodynamics from quantum considerations is presented and it is claimed that inconsistency is the result of faulty analysis, pointing to flaws in approximations. Expand
General conditions for quantum adiabatic evolution
Adiabaticity occurs when, during its evolution, a physical system remains in the instantaneous eigenstate of the Hamiltonian. Unfortunately, existing results, such as the quantum adiabatic theoremExpand
Consistency of the Adiabatic Theorem
The quantum adiabatic approximation for closed systems, and its recently introduced generalization to open systems, are reviewed and a recent argument claiming that there is an inconsistency in the adiABatic theorem is critically examined. Expand
A Quantum Adiabatic Evolution Algorithm Applied to Random Instances of an NP-Complete Problem
For the small examples that the authors could simulate, the quantum adiabatic algorithm worked well, providing evidence that quantum computers (if large ones can be built) may be able to outperform ordinary computers on hard sets of instances of NP-complete problems. Expand
