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…

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…
