Superconductivity in a Chern band: effect of time-reversal-symmetry breaking on superconductivity
Bernhard E. Lüscher, Mark H. Fischer
Time-reversal-symmetry breaking is generally understood to be detrimental for superconductivity. However, recent experiments found superconductivity emerging out of a normal state…

Unconventional gapping behavior in a kagome superconductor
Md Shafayat Hossain, Qi Zhang, Eun Sang Choi +19
Determining the types of superconducting order in quantum materials is a challenge, especially when multiple degrees of freedom, such as bands or orbitals, contribute to the fermio…

Critical properties of the quantum Ashkin-Teller chain with chiral perturbations
Bernhard Lüscher, Frédéric Mila, Natalia Chepiga
We investigate the nature of the phase transitions in the quantum Ashkin-Teller chain in the presence of chiral perturbations. We locate the Lifshitz line separating a region of di…
