Thermodynamic Discovery of Tetracriticality and Emergent Multicomponent Superconductivity in UTe
Sahas Kamat, Jared Dans, Shanta Saha +4
The candidate topological superconductor UTe exhibits a complex phase diagram with multiple superconducting states, yet the nature of their coexistence has remained a central m…
Obstructed Cooper pairs in flat band systems -- weakly-coherent superfluids and exact spin liquids
Tamaghna Hazra, Nishchhal Verma, Jörg Schmalian
Superconductivity in a partially filled flat band presents a vexing conceptual hurdle because the absence of a Fermi surface precludes a weak-coupling regime where one can extend i…
Anomalous Hall viscosity of altermagnets
Iksu Jang, Rui Aquino, Jörg Schmalian +1
We show that the phonon Hall viscosity at zero magnetic field is a natural probe of altermagnetism. First, we demonstrate that the finite elements of the Hall viscosity tensor unam…
Superconductivity in kagome metals due to soft loop-current fluctuations
Daniel J. Schultz, Grgur Palle, Asimpunya Mitra +3
We demonstrate that soft fluctuations of translation symmetry-breaking loop currents provide a mechanism for unconventional superconductivity in kagome metals that naturally addres…
Probing multipolar order in the candidate altermagnet MnF through the elastocaloric effect under strain
Rahel Ohlendorf, Luca Buiarelli, Hilary M. L. Noad +5
Altermagnets break a combination of time-reversal and rotational symmetries without generating a net magnetization. As such, the order parameter of -wave altermagnets has the sa…
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…
