Anomalous Higgs oscillations mediated by Berry curvature and quantum metric
Kristian Hauser A. Villegas, Bo Yang
Higgs spectroscopy, the study of Higgs bosons of a superconductor, is an emerging field in studying superconductivity. Here we show that the Berry curvature and the quantum metric…

Bose-Einstein condensate-mediated superconductivity in graphene
M. Sun, A. V. Parafilo, K. H. A. Villegas +2
We propose a mechanism for robust BCS-like superconductivity in graphene placed in the vicinity of a Bose-Einstein condensate. Electrons in the graphene interact with the excitatio…
