Coupled Ferroelectricity and Superconductivity in Bilayer -MoTe
Apoorv Jindal, Amartyajyoti Saha, Zizhong Li +8
Achieving electrostatic control of quantum phases is at the frontier of condensed matter research. Recent investigations have revealed superconductivity tunable by electrostatic do…
Superconductivity from Orbital-Selective Electron-Phonon Coupling in
Ethan T. Ritz, Henrik S. Røising, Morten H. Christensen +3
Recent experiments have shown that the phase diagrams of the kagome superconductors are strongly impacted by changes in the -axis lattice parameter.…
Cascade of vestigial orders in two-component superconductors: nematic, ferromagnetic, s-wave charge-4e, and d-wave charge-4e states
Matthias Hecker, Roland Willa, Jörg Schmalian +1
Electronically ordered states that break multiple symmetries can melt in multiple stages, similarly to liquid crystals. In the partially-melted phases, known as vestigial phases, a…
Weak-Coupling Theory of Pair Density-Wave Instabilities in Transition Metal Dichalcogenides
Daniel Shaffer, F. J. Burnell, Rafael M. Fernandes
The possibility of realizing pair density wave (PDW) phases, in which Cooper pairs have a finite momentum, presents an interesting challenge that has been studied in a wide variety…
Anomalous Shiba states in topological iron-based superconductors
Areg Ghazaryan, Ammar Kirmani, Rafael M. Fernandes +1
We demonstrate the formation of robust zero energy modes close to magnetic impurities in the iron-based superconductor FeSeTe. We find that the Zeeman field generated b…
The role of electromagnetic gauge-field fluctuations in the selection between chiral and nematic superconductivity
Virginia Gali, Rafael M. Fernandes
Motivated by the observation of nematic superconductivity in several systems, we revisit the problem of the leading pairing instability of two-component unconventional superconduct…
