Title: Machine Learning in Matter at Different Scales
Speaker: Adrien Bouhon from Nordita Title: Weyl nodes with non-Abelian charges Time: Tuesday 17th of September, Fika 10:30-11:00, Seminar 11:00-12:00, Place: Nordita South, room 112:028 . Abstract: Weyl points trapped within a C_2T-symmetric plane (C2 = 180 degrees rotation, and T = time reversal) possess non-Abelian topological charges on top of their […]
Talk by Johan Hellsvik. Title: Impressions from the NNSP-SwedNess Neutron School 2019, Tartu Abstract: The European Spallation Source (ESS) is under development and construction in Lund. The Swedish and international neutron community are running a number of activities and projects in connection to ESS. One such activity is the SwedNess graduate school in neutron scattering. […]
Sahar Pakdel, Aarhus University (Denmark) Title: Exploring 2D-materials in synergy with experimentalists!". Abstract: I will be talking about my experience studying some 2D systems with experimentalists. Specifically I will stress what I consider as the need for flexibility in the theory side while working on systems that are measured at the same time, in comparison […]
Speaker: Adrian Kantian and Gunnar Bollmark (Uppsala University) Title: 1-D electrons coupled to reservoirs: towards new systems of correlated quantum matter and novel devices. Time: Wednesday, 2nd of […]
Condensed Matter Seminar Series Speaker: Vladimir Pudalov, Lebedev Physical Institute Title:"Thermodynamics of the correlated 2D electron system: Entropy per electron and spin magnetization per electron" Abstract: In contrast to ubiquitous transport and optical measurements, interpretation of thermodynamic data is straightforward and is often model independent. However, due to the additive character of thermodynamic properties, their […]
Title: Spin wave dynamics in ultrathin yttriumiron garnet measured with x-ray microscopy Speaker: Joe Bailey, from the PSI (Switzerland) Time: 10:30-11am Fika / 11-12am Talk Abstract: Magnonics, the study and development of devices utilising collective spin excitations, is a rapidly growing field, covering both fundamental topics (antiferromagnetism, quasiparticle condensates) and technological applications (MRAM, spintronics). Yttrium […]

Abstract: Weyl points trapped within a C_2T-symmetric plane (C2 = 180 degrees rotation, and T = time reversal) possess non-Abelian topological charges on top of their chirality. E.g. three-level systems realize the quaternion group. This picture requires to go beyond the modeling of a band structure as a Grassmannian (where a single spectral gap is […]
