Hidden antiferromagnetism, persistent valley fluctuations, and crossovers in triangular-lattice M-point moiré materials via determinantal quantum Monte Carlo
Konstantinos Vasiliou, Dumitru CÄlugÄru, Johannes S. Hofmann +1
A new moiré material platform was recently proposed based on twisting two-dimensional atomic monolayers whose low-energy states lie at the three M-points of the Brillouin Zone. Co…
Cooper Condensation and Pair Wave Functions in Strongly Correlated Electrons
Hannes Karlsson, Johannes S. Hofmann, Alexander Wietek
Identifying superconducting states of matter without prior assumptions is a central challenge in strongly correlated electron systems. We introduce a canonical framework for diagno…
Intertwined Orders, Quantum Criticality and Skyrmions in Tunable Topological Bands
Xuepeng Wang, Johannes S. Hofmann, Debanjan Chowdhury
Skyrmions are emergent many-body excitations that lie at the heart of both multi-component quantum Hall-like systems and deconfined quantum criticality. In a companion article (X.…
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…
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…
