Geometry and non-adiabatic response in quantum and classical systems

M Kolodrubetz, D Sels, P Mehta, A Polkovnikov - Physics Reports, 2017 - Elsevier
In these lecture notes, partly based on a course taught at the Karpacz Winter School in
March 2014, we explore the close connections between non-adiabatic response of a system …

Energy dynamics, heat production and heat–work conversion with qubits: toward the development of quantum machines

L Arrachea - Reports on Progress in Physics, 2023 - iopscience.iop.org

mechanisms for energy conversion in qubit systems with special focus on realizations in …

Second Chern number of a quantum-simulated non-Abelian Yang monopole

S Sugawa, F Salces-Carcoba, AR Perry, Y Yue… - Science, 2018 - science.org
Topological order is often quantified in terms of Chern numbers, each of which classifies a
topological singularity. Here, inspired by concepts from high-energy physics, we use …

Observation of topological transitions in interacting quantum circuits

P Roushan, C Neill, Y Chen, M Kolodrubetz… - Nature, 2014 - nature.com
Topology, with its abstract mathematical constructs, often manifests itself in physics and has
a pivotal role in our understanding of natural phenomena. Notably, the discovery of …

Geometry and response of Lindbladians

VV Albert, B Bradlyn, M Fraas, L Jiang - Physical Review X, 2016 - APS
Markovian reservoir engineering, in which time evolution of a quantum system is governed
