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 [...]
Authors: Cabezas, Carlos; Chang, Ching-Hua; Guillemin, Jean-Claude; Endo, Yasuki Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/10/27 DOI: 10.1039/d2cp03578b Abstract: Fourier transform microwave spectra for two isomers of the chlorine substituted vinyl radical have been observed in the 4-52 GHz frequency region. The observed radicals ((2)A ') have been generated using electric discharges of diluted [...]
El Instituto de Física Fundamental celebra la Semana de la Ciencia 2022 con 9 charlas de divulgación científica y una actividad interactiva (Pub Quiz) dirigidas al público general y jóvenes estudiantes. Las charlas introducirán al público en el apasionante mundo de la física cuántica y sus aplicaciones a computación e información cuánticas, fotónica y simuladores. [...]
Authors: Garbe, Louis; Abah, Obinna; Felicetti, Simone; Puebla, Ricardo Journal: PHYSICAL REVIEW RESEARCH Publication date: 2022/10/26 DOI: 10.1103/PhysRevResearch.4.043061 Abstract: Quantum metrology refers to the use of quantum resources in parameter-estimation protocols, aiming at enhancing its precision. The quantum Fisher information is a key quantity in this context, setting the ultimate achievable precision with respect to [...]
El IFF-CSIC finaliza su ciclo de seminarios del año 2022 con esta charla de la Dra. Nadine Halberstadt (Laboratoire des collisions, Agrégats et Réactivité, CNRS/University of Toulouse 3, France) que se celebrará el miércoles 19 de octubre en la Sala de Conferencias de Serrano 121 a las 12.00 h sobre recientes estudios teóricos de colisiones de [...]
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 [...]
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 [...]
José Cernicharo, profesor de investigación en nuestro instituto, ha sido galardonado con el reconocimiento más importante de España en el ámbito de la investigación científica, el Premio Nacional de Investigación Blas Cabrera, en el área de Ciencias Físicas, de los Materiales y de la Tierra, concedido por el Ministerio de Ciencia e Innovación, dentro de [...]
Authors: Benedek, G.; Manson, J. R.; Miret-Artes, Salvador Journal: PHYSICAL CHEMISTRY CHEMICAL PHYSICS Publication date: 2022/10/05 DOI: 10.1039/d2cp03501d Abstract: In previous works it has been shown that the Debye-Waller (DW) exponent for Helium atom specular reflection from a conducting surface, when measured as a function of temperature in the linear high-temperature regime, allows for the [...]
