Kibble-Zurek mechanism of Ising domains
Kai Du, Xiaochen Fang, Choongjae Won +5
The formation of topological defects after a symmetry-breaking phase transition is an overarching phenomenon that encodes rich information about the underlying dynamics. Kibble-Zur…
Locality of Spontaneous Symmetry Breaking and Universal Spacing Distribution of Topological Defects Formed Across a Phase Transition
Adolfo del Campo, Fernando Javier Gómez-Ruiz, Hai-Qing Zhang
The crossing of a continuous phase transition results in the formation of topological defects with a density predicted by the Kibble-Zurek mechanism (KZM). We characterize the spat…
Benchmarking quantum annealing dynamics: the spin-vector Langevin model
David Subires, Fernando J. Gómez-Ruiz, Antonia Ruiz-García +2
The classical spin-vector Monte Carlo (SVMC) model is a reference benchmark for the performance of a quantum annealer. Yet, as a Monte Carlo method, SVMC is unsuited for an accurat…
Enhancing violations of Leggett-Garg inequalities in nonequilibrium correlated many-body systems by interactions and decoherence
J. J. Mendoza-Arenas, F. J. Gómez-Ruiz, F. J. Rodríguez +1
We identify different schemes to enhance the violation of Leggett-Garg inequalities in open many-body systems. Considering a nonequilibrium archetypical setup of quantum transport,…
Chapter: Vulnerability of Quantum Information Systems to Collective Manipulation
Fernando J. Gómez-Ruiz, Ferney J. Rodríguez, Luis Quiroga +1
The highly specialist terms `quantum computing' and `quantum information', together with the broader term `quantum technologies', now appear regularly in the mainstream media. Whil…
Universal dynamics of inhomogeneous quantum phase transitions: suppressing defect formation
F. J. Gómez-Ruiz, A. del Campo
In the nonadiabatic dynamics across a quantum phase transition, the Kibble-Zurek mechanism predicts that the formation of topological defects is suppressed as a universal power law…
