Quantum geometry and impurity sensitivity of superconductors without time-reversal symmetry: application to rhombohedral graphene and altermagnets
Denis Sedov, Mathias S. Scheurer
Analyzing the consequences of the quantum geometry induced by the momentum dependence of Bloch states has emerged as a very rich and active field in condensed matter physics. For i…
Vestigial pairing from fluctuating magnetism and triplet superconductivity
Yanek Verghis, Denis Sedov, Jakob WeÃling +2
We study the finite-temperature vestigial superconducting phases of a two-dimensional system of fluctuating spin-triplet pairing and spin magnetism. Denoting the respective primary…
Probing superconductivity with tunneling spectroscopy in rhombohedral graphene
Denis Sedov, Mathias S. Scheurer
Motivated by experiments on rhombohedral tetralayer graphene showing signs of superconductivity emerging from a valley-polarized normal state, we here analyze theoretically how sca…
Probing the flat-band limit of the superconducting proximity effect in Twisted Bilayer Graphene Josephson junctions
A. Diez-Carlon, J. Diez-Merida, P. Rout +13
While extensively studied in normal metals, semimetals and semiconductors, the superconducting (SC) proximity effect remains elusive in the emerging field of flat-band systems. In…
