Pairing from repulsive interactions in twisted WSe2 from functional renormalization
Hannes Braun, Dumitru Călugăru, Pietro M. Bonetti +9
Motivated by the observation of superconductivity in twisted bilayer WSe over an extended range of displacement fields, reaching from the correlated insulator down to zero fiel…
Relativistic Mott transitions and finite-temperature effects of quantum criticality in Dirac semimetals
Mireia Tolosa-Simeón, Laura Classen, Michael M. Scherer
Gross-Neveu-Yukawa-type models such as the chiral Ising, chiral XY, and chiral Heisenberg models, serve as effective descriptions of two-dimensional Dirac semi-metals undergoing qu…
Mean-field analysis of a Hubbard interaction on Bernal Bilayer Graphene
Robin Scholle, Laura Classen
We perform unrestricted Hartree-Fock calculations on the 2D Hubbard model on a honeycomb and bilayer honeycomb lattice at both zero and finite temperatures. Finite size real space…
Angle-Tuned Gross-Neveu Quantum Criticality in Twisted Bilayer Graphene: A Quantum Monte Carlo Study
Cheng Huang, Nikolaos Parthenios, Maksim Ulybyshev +4
The fascinating quantum many-body states in twisted bilayber graphene (TBG) at magic angle, due to the interplay of Coulomb interactions and the quantum metrics of flat bands, have…
Competing phases in kagome magnet FeGe from functional renormalization
Pietro M. Bonetti, Yi Jiang, Haoyu Hu +4
The discovery of a charge density wave in FeGe extends the discussion of the nature of charge order in kagome metals to a magnetic compound. Motivated by this observation, we combi…
Kohn-Luttinger-like mechanism for unconventional charge density waves
Hannes Braun, Michael M. Scherer, Laura Classen
Interaction-induced charge orders with electronic origin occur as states of spontaneously broken symmetry in several materials platforms. An electronic mechanism for charge order r…
