A binary black hole merger rate comparison within the same metallicity - star formation rate framework
Lumen Boco, Michele Bosi, Cecilia Sgalletta +2
Recent studies have suggested that binary population synthesis models, when coupled with observationally based, metallicity-dependent star formation rate density, overpredict the o…
Fermiology and spin polarization of topological surface states in PtBi
Anders Christian Mathisen, Xin Liang Tan, Stefanie Suzanne Brinkman +12
Layered PtBi is a candidate for topological superconductivity arising in Fermi-arc surface states. Using spin- and angle-resolved photoemission spectroscopy, we demonstrate tha…
Inherent Altermagnetism on regular hyperbolic lattices
Eric Petermann, Kristian Mæland, Haye Hinrichsen +1
Altermagnets are a novel class of magnetic systems characterized by their momentum-dependent spin splitting without net magnetization. In this work, we extend established Euclidean…
Topological Edge States Emerging from Twisted Moiré Bands
Yasser Saleem, PaweÅ Potasz, Anna DyrdaÅ +2
We study twisted bilayer WSe within a continuum moiré model and introduce a method for treating finite geometries directly in the continuum framework, overcoming limitations a…
Mechanism for Nodal Topological Superconductivity on PtBi Surface
Kristian Mæland, Giorgio Sangiovanni, Björn Trauzettel
Experiments show that the Weyl semimetal PtBi hosts unconventional superconductivity in its topological surface states. Hence, the material is a candidate for intrinsic topolog…
Diode effect in microwave irradiated Josephson junctions with Yu-Shiba-Rusinov states
Aritra Lahiri, Marcel Polák, Björn Trauzettel
We investigate the critical current in microwave-irradiated Josephson junctions hosting Yu-Shiba-Rusinov states due to magnetic impurities. Under two conditions, namely, (i) the br…
