A novel simulation procedure allows new insights on ectopic beats in the heart
Ramon y Cajal researcher in the Physics department Sergio Alonso publishes, in collaboration with Brazilian Universidade Federal de Juiz de Fora and the Deutsches Herzzentrum Berlin, a novel simulation method to understand how the hearts can beat anomalously with a signal originating from the same heart (ectopic beat) instead of our natural external pacemaker.

Adrià Casanovas Hoste defends his thesis on measures of effective neutron capture sections of importance for the study of stellar nucleosynthesis
Adrià Casanovas Hoste defended his thesis, co-directed by Franciscño Calviño (UPC) and César Domingo (IFIC, Valencia), on 27 October at the ETSEIB. Titled "Neutron capture cross section measurement of the heaviest s-process branching 204Tl and of 203Tl at CERN n_TOF", the thesis presents the first ever measurement of the effective neutron capture section of the radioactive isotope of such 204Tl, of special relevance to the slow process of stellar nucleosynthesis, and performed in the CERN n_TOF experiment

An international team of physicists carry out quantum simulation of the physical effects of disorder in topological insulators
A team of researchers from the University of Illinois at Urbana-Champaign, the United States, the Institute of Photonic Sciences (ICFO) and the UPC uses experiments with ultra-cold atoms, trapped and driven by lasers, to create a new topological insulator induced by the disorder.

Analysis of the last two centuries of rainfall records in Andalusia for the detection of possible changes caused by global warming
As a result of a collaboration with researchers from the University of Córdoba, M. Carmen Casas and Raúl Rodríguez have evaluated the quality of the rainfall data of Andalusia available since 1870, long before the first modern meteorological stations were put into operation, and have analyzed the different rainfall patterns in the region in pursuit of the detection of possible changes caused by global warming

Are dislocations in solid helium “supersolid”?
A team of researchers from the Universitat Politècnica de Catalunya (Spain), Universidade Estadual de Campinas (Brazil) and Stanford University (USA) performed advanced quantum atomistic simulations to assess the Bose-Einstein condensate fraction of solid helium at zero temperature containing dislocations, a defective system that previously had been proposed to be “supersolid”
