| 11:00 - 12:00 Computational Nano Science journal club Thermally driven domain-wall motion in Fe on W(110) School NANO SCIENCES Thermally driven domain-wall motion in Fe on W(110) It has recently been shown that domain walls (DWs) in ferromagnets can be moved in the presence of thermal gradients. In this work we study the motion of narrow domain walls in low-dimensional systems when subjected to thermal gradients. The system chosen is a monolayer of Fe on W(110) which is known to exhibit a large anisotropy while having a soft exchange, resulting in a very narrow domain wall. The study is performed by means of atomistic spin dynamics simulations coupled to first-principles calculations. By subjecting this system to thermal gradients we observe a tempe ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Disorder free many-body localization School PHYSICS Seminar Room (classroom A), Farmanieh Building, IPM ... 14:00 - 15:00 Weekly Seminar Disorder free many-body localization School NANO SCIENCES Disorder free many-body localization One of the central questions of quantum statistical physics is how isolated many-body systems reach thermal equilibrium. Two decades ago, the eigenstate thermalization hypothesis (ETH) was proposed as a mechanism accounting for the validity of the statistical mechanics in isolated quantum systems. In contrast, many-body localization (MBL) that arises from the competition between disorder and interactions, has opened the door to the investigation of breakdown of quantum ergodicity. This raises the appealing prospect of protecting quantum order as well as storing and manipulating coherent i ... 15:30 - 16:30 Weekly Seminar Determining Neutrino Oscillation Parameters in Presence of NSI School PARTICLES AND ACCELERATORS To measure the last unknown three neutrino oscillation parameter, several long-baseline neutrino experiments have been designed or proposed. Recently it has been shown that turning on neutral current Non-Standard Interactions (NSI) of neutrinos with matter can induce degeneracies that may even hinder the proposed state-of-the-art DUNE long baseline experiment from measuring the value. We study how the result of the proposed MOMENT experiment with a baseline of 150 km and 200 MeV |
