Mode-selective phonon effects on magnetism and superconductivity in trilayer nickelates
C. Alexander Baum, Jun Zhan, Congcong Le +2
The discovery of high- superconductivity in multilayer nickelates has stimulated intense interest, yet the microscopic origins of their correlated states remain debated. Recen…
Pair density wave order from non-symmorphic momentum symmetry
Matteo Dürrnagel, C. Alexander Baum, Michael Klett +2
We develop a class of microscopic lattice models in which pair density wave order emerges in the asymptotically exact weak coupling limit. The underlying mechanism is due to non-sy…
Extended s-wave superconductivity in M-point twisted bilayer SnSe2
Lennart Klebl, Ammon Fischer, Salahudin V. Smailagić +6
We investigate the emergence of electronic order and unconventional superconductivity in M-valley moiré materials. Starting from a first-principles Wannier model of AB-stacked twis…
Slave-boson Formalism for Superconducting Pairing at Strong Coupling
Sarbajit Mazumdar, Jonas Issing, Jannis Seufert +4
We study the emergence of superconductivity in the one-band Hubbard model using the spin-rotation-invariant Kotliar-Ruckenstein slave-boson (SB) approach. Motivated by its intrinsi…
Phase-sensitive evidence for pair density waves in a kagome superconductor
Xiao-Yu Yan, Guowei Liu, Hanbin Deng +22
Pair density wave (PDW) exhibits periodic amplitude and sign modulations of the superconducting order parameter. Such a pairing state has long been proposed to be highly sensitive…
Distinct Uniaxial Stress and Pressure Fingerprint of Superconductivity in the 3D Kagome Lattice Compound CeRu2
O. Gerguri, D. Das, V. Sazgari +16
The exploration of tunable superconductivity in strongly correlated electron systems is a central pursuit in condensed matter physics, with implications for both fundamental unders…
