Pseudo Point Nodal Superconducting Gap in Spin-Triplet UTe
S. Hosoi, K. Imamura, M. M. Bordelon +7
The unconventional superconductor UTe represents a rare example of spin-triplet pairing with potentially topologically protected quantum states. However, conflicting reports on…
Finite-momentum superconductivity from chiral bands in twisted MoTe

We develop a field theory formulation for the interaction of an ensemble of two-level tunneling systems (TLS) with the electronic states of a superconductor. Predictions for the im…
Intrinsic superconducting diode effect and nonreciprocal superconductivity in rhombohedral graphene multilayers
Yinqi Chen, Mathias S. Scheurer, Constantin Schrade
Recent experiments have revealed that superconductivity in rhombohedral tetralayer graphene can emerge from a valley-polarized and, hence, chiral normal state. The interplay of pai…

Superconducting spintronics explores the interplay between superconductivity and magnetism, sparking significant interest in nonunitary superconductors as a platform for novel magn…
A-B transition in superfluid He and cosmological phase transitions
Mark Hindmarsh, J. A. Sauls, Kuang Zhang +10
First order phase transitions in the very early universe are a prediction of many extensions of the Standard Model of particle physics and could provide the departure from equilibr…
Tuning the Josephson diode response with an ac current
Rubén Seoane Souto, Martin Leijnse, Constantin Schrade +3
Josephson diodes are superconducting elements that show an asymmetry in the critical current depending on the direction of the current. Here, we theoretically explore how an altern…
