The spin-vector Langevin model

Our postdoctoral researcher Fernando J. Gómez-Ruiz together with a team of researchers from Donostia International Physics Center, Universidad de la Laguna, and the University of Luxembourg introduced the spin-vector Langevin model as an alternative benchmark for the performance of a quantum annealer.  State-of-the-art quantum annealers are an example of noisy intermediate-scale quantum devices in…

Phase Diagram of 1+1D Abelian-Higgs Model and Its Critical Point

Our Luca Tagliacozzo together with a team of researchers from Jagiellonian University of Cracow, and ICFO uncovers hidden gems lurking behind the Abelian-Higgs model in one spatial dimension and time.The Higgs mechanism, through which gauge bosons acquire a mass allows to understand how weak interactions can be short-ranged. This mechanism is absent in…
