Low-temperature scaling laws in unconventional flat-band superconductors
Maximilian Buthenhoff, Yusuke Nishida
In flat-band superconductors, the electron pairing is strongly enhanced so that the critical temperature scales linearly with the interaction strength. Identifying the governing pa…

Quantum-geometric thermal conductivity of superconductors
Maximilian Buthenhoff, Yusuke Nishida
By coupling Bardeen-Cooper-Schrieffer (BCS) theory with isolated bands to an external gravitomagnetic vector potential via a gravitomagnetic Peierls substitution, we identify a qua…

Kondo effect under arbitrary spin-momentum locking
Kinari Goto, Yusuke Nishida
The Kondo effect originates from the spin exchange scattering of itinerant electrons with a localized magnetic impurity. Here, we consider generalization of Weyl-type electrons wit…
