Strain-Tuned Incommensurate Kekulé Spiral Order in Twisted Bilayer Graphene: a Quantum Many-Body Study
Cheng Huang, Yves H. Kwan, Maksim Ulybyshev +3
The understanding of quantum many-body states in twisted bilayer graphene at the magic angle has been greatly improved both in experiment and in theory. However, away from the exac…
T-linear specific heat in pressurized and magnetized Shastry-Sutherland Mott insulator SrCu2(BO3)2
Jing Guo, Pengyu Wang, Cheng Huang +13
The pressurized Shastry-Sutherland Mott insulator SrCu2(BO3)2 has been found to host a plaquette-singlet phase and an antiferromagnetic phase that break different symmetries sponta…
Phase transitions and remnants of fractionalization at finite temperature in the triangular lattice quantum loop model
Xiaoxue Ran, Sylvain Capponi, Junchen Rong +2
The quantum loop and dimer models are archetypal correlated systems with local constraints. With natural foundations in statistical mechanics, they are of direct relevance to vario…
Symmetrizing the Constraints -- Density Matrix Renormalization Group for Constrained Lattice Models
Ting-Tung Wang, Xiaoxue Ran, Zi Yang Meng
We develop a density matrix renormalization group (DMRG) algorithm for constrained quantum lattice models that successfully {\it{implements the local constraints as symmetries in t…
