Elastic Quantum Criticality in Nematics and Altermagnets via the Elasto-Caloric Effect
Charles R. W. Steward, Grgur Palle, Markus Garst +2
The coupling between electronic nematic degrees of freedom and acoustic phonons is known to significantly alter the universality class of a nematic quantum critical point (QCP). Wh…

Topological dipoles of quantum skyrmions
Sopheak Sorn, Jörg Schmalian, Markus Garst
Magnetic skyrmions are spatially localized whirls of spin moments in two dimension, featuring a nontrivial topological charge and a well-defined topological charge density. We demo…

Pairing at a single Van Hove point
Risto Ojajärvi, Andrey V. Chubukov, Yueh-Chen Lee +2
We show that an interacting electronic system with a single ordinary or extended Van Hove point, which crosses the Fermi energy, is unstable against triplet superconductivity. The…
