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…
Organizing Principles for Moiré Quantum Matter
Qiaoling Xu, Yifan Gao, Tao Zhang +16
Moiré flat bands in van der Waals bilayers are usually discussed through a small set of mechanisms associated with the and valleys of hexagonal crystals, and more recentl…
Cavity-enhanced superconducting response in an underdoped cuprate
Angela Montanaro, Vadim Plastovets, Nitesh Khatiwada +15
Superconductors carry electrical current without resistance when paired electrons condense into a coherent macroscopic quantum state. In underdoped cuprates, evidence suggests that…
Surface Functional Renormalization Group for Layered Quantum Materials
Lennart Klebl, Dante M. Kennes
We present an extension to the two-dimensional functional renormalization group to efficiently treat interactions on the surface or at interfaces of three-dimensional systems. As a…
Supercurrent Growth in Nonequilibrium Superconductors
Qinghong Yang, Yuqi Cao, Dante M. Kennes +1
In ultrafast experiments on superconductors, a pump laser pulse often heats up the electronic system and suppresses the density of superfluid electrons. Subsequently, the electrons…
Floquet Engineering Magnetism and Superconductivity in the Square-Lattice Hubbard Model
Jan-Niklas Herre, Takuya Okugawa, Ammon Fischer +2
We study the interplay of magnetic order and superconductivity in the square-lattice Hubbard model under periodic driving with circularly polarized light. Formulating diagrammatic…
