Title: Machine learning of equivariant functions inspired by atomistic modelling and three-dimensional image processing. Speaker: Bastiaan J. Braams, Centrum Wiskunde & Informatica (CWI), Amsterdam, The Netherlands. Abstract: Over the past several years big data methods, including but not limited to use of deep convolutional neural networks, have been very successful in computer science applications and […]

Title: Efficient tensor network representation for Gutzwiller projected states of paired fermions Abstract: Recent work by Y.H. Wu {\em et al}, proposed a numerical method, so called MPO-MPS method, by which several types of quantum many-body wave functions, in particular, the projected Fermi sea state, can be efficiently represented as a tensor network. In this paper, […]

Speaker: Danny Thonig (Örebro Universitet) Title: Ultrafast magnetism from ab-initio atomistic magnetisation dynamics Time: Fika 10:30-11:00 , Seminar 11:00-12:00, Place: Nordita South, room 112:028 . Abstract: Writing and retrieving information in a magnetic material at high speed and with lower energy consumption has become an intense research field in solid state physics, since there is […]

  Title: A hydrodynamical description for transport in the strange metal phase of cuprates  Speaker: Andrea Amoretti (Genova) The talk is on Monday 10 February 2020, 13:15, room 132:028 (Nordita East). Abstract: High temperature superconductors are strongly coupled systems which present a complicated phase diagram with many coexisting phases. This makes it difficult to understand […]

Title: Weyl semimetals in torsional spacetime Abstract: Weyl semimetals necessarily break the time-reversal or/and inversion symmetry. In the presence of spatially varying time-reversal or inversion symmetry breaking fields, we show that the Weyl fermions live in emergent torsional spacetime . This allows us to fabricate interface between type I and type II Weyl semimetals , which is […]
