On the Metastability of the Mean-Field Interchange Model for Local Dimension
Sergio Escobar, Lin Lin, Michael Ragone +1
Many quantum systems are believed to thermalize slowly at low temperatures due to the existence of metastable phases. However, there are cases where further cooling can restore pol…
Relaxation effects on Hartree-Fock ground states in twisted bilayer graphene at even integer fillings
Tianyu Kong, Alexander B. Watson, Lin Lin +2
A standard approach for studying magic angle twisted bilayer graphene (MATBG)'s correlated electronic phase diagram is to project the Coulomb interaction down to effective models o…
Exactly flat bands beyond the chiral limit in Bistritzer--MacDonald Hamiltonians
Zhen Huang, Kevin D. Stubbs
The chiral limit of the Bistritzer--MacDonald model for twisted bilayer graphene has exactly flat bands at magic angles. We show that exact flatness can persist beyond the chiral l…
Hartree--Fock coercivity for twisted bilayer graphene
Kevin D. Stubbs, Maciej Zworski
We study the minimisers of the Hartree--Fock functional for flat bands in the chiral model of twisted bilayer graphene introduced by Tarnopolsky, Kruchkov, and Vishwanath. Our mode…
Spectral Gap of the Davies Generator for the Mean-Field Heisenberg Model
Joao Basso, Thiago Bergamaschi, Lin Lin +2
The mean-field Heisenberg ferromagnet is a quantum spin model on the complete graph with isotropic spin-1/2 interactions. This non-commuting Hamiltonian is permutation and $\mathsf…
Ab initio quantum embedding description of magic angle twisted bilayer graphene at even-integer fillings
Raehyun Kim, Woochang Kim, Kevin D. Stubbs +2
Magic angle twisted bilayer graphene (MATBG) hosts narrow moiré bands with meV-scale energy splittings, making its correlated phases sensitive to both material parameters and model…
