Full Counting Statistics of Topological Defects After Crossing a Phase Transition
Fernando J. Gómez-Ruiz, Jack J. Mayo, Adolfo del Campo
We consider the number distribution of topological defects resulting from the finite-time crossing of a continuous phase transition and identify signatures of universality beyond t…
Shortcuts to Adiabaticity in Driven Open Quantum Systems: Balanced Gain and Loss and Non-Markovian Evolution
S. Alipour, A Chenu, A. T. Rezakhani +1
A universal scheme is introduced to speed up the dynamics of a driven open quantum system along a prescribed trajectory of interest. This framework generalizes counterdiabatic driv…
An Interaction-Driven Many-Particle Quantum Heat Engine: Universal Behavior
Yang-Yang Chen, Gentaro Watanabe, Yi-Cong Yu +2
A quantum heat engine (QHE) based on the interaction driving of a many-particle working medium is introduced. The cycle alternates isochoric heating and cooling strokes with both i…
Probing the Full Distribution of Many-Body Observables by Single-Qubit Interferometry
Zhenyu Xu, Adolfo del Campo
We present an experimental scheme to measure the full distribution of many-body observables in spin systems, both in and out of equilibrium, using an auxiliary qubit as a probe. We…
Extreme Decoherence and Quantum Chaos
Zhenyu Xu, Luis Pedro García-Pintos, Aurélia Chenu +1
We study the ultimate limits to the decoherence rate associated with dephasing processes. Fluctuating chaotic quantum systems are shown to exhibit extreme decoherence, with a rate…
Quantum Speed Limits under Continuous Quantum Measurements
Luis Pedro García-Pintos, Adolfo del Campo
The pace of evolution of physical systems is fundamentally constrained by quantum speed limits (QSL), which have found broad applications in quantum science and technology. We cons…
