Extended s-wave superconductivity in M-point twisted bilayer SnSe2
Lennart Klebl, Ammon Fischer, Salahudin V. SmailagiÄ +6
The authors model twisted bilayer SnSe2 with an M‑point moiré pattern and use functional renormalization group calculations to show that doping drives a transition from antiferroma…
Exotic Electronic Order in a Parabolic Kagome Semimetal
C. Alexander Baum, Jonas Issing, Sarbajit Mazumdar +4
We study an interacting kagome-lattice realization of a quadratic band-touching semimetal at 2/3 filling with onsite and nearest-neighbor repulsive interactions. Combining function…
Electron-Phonon Functional Renormalization Group of Fermi Liquid Instabilities
C. Alexander Baum, Matteo Dürrnagel, Ronny Thomale +1
We formulate a functional renormalization group (FRG) ansatz for correlated electron models that incorporates electronic interactions as well as electron-phonon coupling (EPC) stem…
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…
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…
Large-flavor route to a stable U(1) Dirac spin liquid on the maple-leaf lattice
Yunchao Zhang, Andreas Feuerpfeil, Subir Sachdev +2
The Dirac spin liquid provides a useful organizing framework for frustrated magnets: it offers an algebraic parent state from which competing orders, confinement pa…
