Open quantum rotors: Connecting correlations and physical currents

2023-01-27T15:32:16+01:00Tags: , |

Authors: Puebla, Ricardo; Imparato, Alberto; Belenchia, Alessio; Paternostro, Mauro Journal: PHYSICAL REVIEW RESEARCH Publication date: 2022/10/28 DOI: 10.1103/PhysRevResearch.4.043066 Abstract: We consider a finite one-dimensional chain of quantum rotors interacting with a set of thermal baths at different temperatures. When the interaction between the rotors is made chiral, such a system behaves as an autonomous thermal [...]

Locality of spontaneous symmetry breaking and universal spacing distribution of topological defects formed across a phase transition

2023-01-27T15:32:16+01:00Tags: , , , |

Authors: del Campo, Adolfo; Javier Gomez-Ruiz, Fernando; Zhang, Hai-Qing Journal: PHYSICAL REVIEW B Publication date: 2022/10/11 DOI: 10.1103/PhysRevB.106.L140101 Abstract: 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 spatial distribution of pointlike topological defects in the resulting nonequilibrium [...]

Role of boundary conditions in the full counting statistics of topological defects after crossing a continuous phase transition

2023-01-27T15:32:16+01:00Tags: , , , |

Authors: Gomez-Ruiz, Fernando J.; Subires, David; del Campo, Adolfo Journal: PHYSICAL REVIEW B Publication date: 2022/10/10 DOI: 10.1103/PhysRevB.106.134302 Abstract: In a scenario of spontaneous symmetry breaking in finite time, topological defects are generated at a density that scales with the driving time according to the Kibble-Zurek mechanism (KZM). Signatures of universality beyond the KZM have [...]
