Unconventional bond- and current-density waves on hexagonal lattices
Andras Szabo, Hannes Braun, Laura Classen
Charge-density wave (CDW) orders are conventionally described as modulations of on-site charge at an ordering wave vector with symmetry-related wave vectors typica…
Intervalley coherence and flavor polarization in three-valley moiré systems
Jeyong Park, Laura Classen, Mathias S. Scheurer
We investigate interaction-induced symmetry breaking in moiré superlattices created by twisting two identical materials where the electronic low-energy degrees of freedom reside in…
Strain-Tuned Incommensurate Kekulé Spiral Order in Twisted Bilayer Graphene: A Quantum Many-Body Study
Cheng Huang, Yves H. Kwan, Maksim Ulybyshev +3
The physics of twisted bilayer graphene away from the exactly solvable chiral limit and the quantum Monte Carlo sign-problem-free charge neutrality point is elusive due to the expo…
Quantum Geometric Origin of the Intrinsic Nonlinear Hall Effect
Yannis Ulrich, Johannes Mitscherling, Laura Classen +1
We decompose the intrinsic second-order nonlinear Hall effect (NLHE) of a generic multiband system into its quantum-geometric contributions within a fully quantum-mechanical, proje…
Van-Hove singularities and competing instabilities in an altermagnetic metal
Peng Rao, Johannes Knolle, Laura Classen
Van-Hove (VH) singularities in the single-particle band spectrum are important for interaction-driven quantum phases. Whereas VH points are usually spin-degenerate, in newly propos…
Spin and pair density waves in 2D altermagnetic metals
Nikolaos Parthenios, Pietro M. Bonetti, Rafael González-Hernández +3
Altermagnetism, a recently proposed and experimentally confirmed class of magnetic order, features collinear compensated magnetism with unconventional d-, g-, or i-wave spin order.…
