Hopf symmetry protected topological phases in the vicinity of spin orders
Grgur Palle
Hopf terms are topological theta terms that are associated with a host of interesting physics, including anyons, statistical transmutation, chiral edge states, and the spin quantum…

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…

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…
