Speaker: Markus Müller Affiliation: Paul Scherrer Institut (PSI) in Switzerland Title: Coherent oscillators, spectral hole-burning and emerging q-bits in rare earth magnets Abstract: Experiments in rare earth compounds, such as LiHoYF4 and GGG (Gd-Ga-garnet), have demonstrated very long lived, coherent quantum degrees of freedom with sharply defined excitation energies, many orders of magnitude below the […]
Speaker: Shota Kanasugi Affiliation: Kyoto University Title: Spin-orbit-coupled ferroelectric superconductivityand multiorbital effects in SrTiO3 Abstract: A lot of exotic superconducting statesemerge close to other ordered phases, such as anisotropic superconductivity in cuprates. Although previous studies have mainly focused on the superconductivityclose to magnetic instability, the ferroelectric (FE) counterpart is recently receiving increased attention since such […]
Speaker: Ipsita Mandal Affiliation: University of Stavanger, Title: Some aspects of correlated electrons, Time: Fika 10:30-11:00 , Seminar 11:00-12:00, Place: Nordita South, room 112:028 . Abstract: In this talk, I am going to present exciting results from two of my ongoing/recent projects. First part: Spin-orbit coupling (SOC) assisted (spin j = 1/2) Mott insulators […]
Speaker: Manuel Simonato Title: On the spectral properties of inhomogeneous Luttinger liquids Abstract: The physics of one-dimensional systems of interacting fermions strongly differs from the picture offeredby Fermi liquid theory. The low-energy properties of metallic, paramagnetic 1D Fermi systems arewell described by the Luttinger liquid (LL) theory. Among other properties, the homogeneous LL isknown to […]

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 […]
