Spin-Polaron Mediated Superconductivity in Doped Chern Antiferromagnets
Xuepeng Wang, J. F. Mendez-Valderrama, Johannes S. Hofmann +1
The study of interacting topological bands with a tunable bandwidth offers a unique platform to study the interplay of intertwined orders and emergent non-electronic excitations. H…
Low-energy optical absorption in correlated insulators: Projected sum rules and the role of quantum geometry
Dan Mao, Juan Felipe Mendez-Valderrama, Debanjan Chowdhury
Inspired by the discovery of a variety of correlated insulators in the moiré universe, controlled by interactions projected to a set of isolated bands with a narrow bandwidth, we e…
Correlated Topological Mixed-Valence Insulators in Moiré Hetero-Bilayers
Juan Felipe Mendez-Valderrama, Sunghoon Kim, Debanjan Chowdhury
Moiré transition metal dichalcogenide (TMD) materials provide an ideal playground for studying the combined interplay of strong interactions and band-topology over a range of elect…
Theory of Correlated Insulators and Superconductor at in Twisted WSe
Sunghoon Kim, Juan Felipe Mendez-Valderrama, Xuepeng Wang +1
The observation of a superconducting phase, an intertwined insulating phase, and a continuous transition between the two at a commensurate filling of in bilayers of twisted W…
Intertwined Magnetism and Superconductivity in Isolated Correlated Flat Bands
Xuepeng Wang, J. F. Mendez-Valderrama, Johannes S. Hofmann +1
Multi-orbital electronic models hosting a non-trivial band-topology in the regime of strong electronic interactions are an ideal playground for exploring a host of complex phenomen…
The Oxygen Reduction Pathway for Spinel Metal Oxides in Alkaline Media: An Experimentally Supported Ab Initio Study
Colin R. Bundschu, Mahdi Ahmadi, Juan F. Méndez-Valderrama +3
Precious-metal-free spinel oxide electrocatalysts are promising candidates for catalyzing the oxygen reduction reaction (ORR) in alkaline fuel cells. In this theory-driven study, w…
Investigation of Planckian behavior in a high-conductivity oxide: PdCrO
Elina Zhakina, Ramzy Daou, Antoine Maignan +12
The layered delafossite metal PdCrO is a natural heterostructure of highly conductive Pd layers Kondo coupled to localized spins in the adjacent Mott insulating CrO layers.…
linear resistivity from magneto-elastic scattering: application to PdCrO
J. F. Mendez-Valderrama, Evyatar Tulipman, Elina Zhakina +3
An electronic solid with itinerant carriers and localized magnetic moments represents a paradigmatic strongly correlated system. The electrical transport properties associated with…
Intermediate-scale theory for electrons coupled to frustrated local-moments
Adam J. McRoberts, J. F. Mendez-Valderrama, Roderich Moessner +1
A classic route for destroying long-lived electronic quasiparticles in a weakly interacting Fermi liquid is to couple them to other low-energy degrees of freedom that effectively a…
Bad metallic transport in geometrically frustrated models
J. F. Mendez-Valderrama, Debanjan Chowdhury
We study the transport properties for a family of geometrically frustrated models on the triangular lattice with an interaction scale far exceeding the single-particle bandwidth. S…
