Authors: Arrayas, Manuel; Tiemblo, Alfredo; Trueba, Jose L. Journal: CHAOS SOLITONS & FRACTALS Publication date: 2023/01/01 DOI: 10.1016/j.chaos.2022.113002 Abstract: In this work we find new null electromagnetic fields that are exact solutions of Maxwell equations in vacuum and generalize the hopfion. The hopfion is an exact solution of Maxwell equations in vacuum in which all [...]
Authors: Cortes-Vega, J.; Barra, J. F.; Pereira, L.; Delgado, A. Journal: QUANTUM INFORMATION PROCESSING Publication date: 2023/05/09 DOI: 10.1007/s11128-023-03953-y Abstract: Entangled states play a fundamental role in quantum mechanics and are at the core of many contemporary applications, such as quantum communication and quantum computing. Therefore, determining whether a state is entangled or not is [...]
Authors: Robertson, Niall F.; Surace, Jacopo; Tagliacozzo, Luca Journal: PHYSICAL REVIEW B Publication date: 2022/05/04 DOI: 10.1103/PhysRevB.105.195103 Abstract: Conformal field theories (CFTs) have been used extensively to understand the physics of critical lattice models at equilibrium. However, the applicability of CFT calculations to the behavior of the lattice systems in the out-of-equilibrium setting is not [...]
Authors: Lozano, Ana I.; Kossoski, Fabris; Blanco, Francisco; Limao-Vieira, Paulo; Varella, Marcio T. do N.; Garcia, Gustavo Journal: JOURNAL OF PHYSICAL CHEMISTRY LETTERS Publication date: 2022/08/04 DOI: 10.1021/acs.jpclett.2c01704 Abstract: Low-energy electrons (LEEs) can very efficiently induce bond breaking via dissociative electron attachment (DEA). While DEA is ubiquitous, the importance of other reactions initiated by LEEs [...]
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 [...]
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 [...]

Journal: JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL Publication date: 2022/11/25 DOI: 10.1088/1751-8121/aca36e Abstract: Decoherence is a well established process for the emergence of classical mechanics in open quantum systems. However, it can have two different origins or mechanisms depending on the dynamics one is considering, speaking then about intrinsic [...]
Authors: Nation, Charlie; Porras, Diego Journal: JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL Publication date: 2022/11/25 DOI: 10.1088/1751-8121/aca3dc Abstract: In this work we study a scenario where unitary quantum dynamics in a many-body interacting system is restricted to a single excitation subspace. We ask how dynamics within to such a subspace may in general differ from [...]

Authors: Hernandez, Marta I.; Bartolomei, Massimiliano; Campos-Martinez, Jose Journal: NANOMATERIALS Publication date: 2021/01/01 DOI: 10.3390/nano11010073 Abstract: We report accurate quantum calculations of the sieving of Helium atoms by two-dimensional (2D) graphtriyne layers with a new interaction potential. Thermal rate constants and permeances in an ample temperature range are computed and compared for both Helium isotopes. [...]
