VASP2KP: kp models and Lande g-factors from ab initio calculations
Sheng Zhang, Haohao Sheng, Zhi-Da Song +8
The method is significant in condensed matter physics for the compact and analytical Hamiltonian. In the presence of magnetic field, it is described by the effective Zee…
Spin Space Groups: Full Classification and Applications
Zhenyu Xiao, Jianzhou Zhao, Yanqi Li +2
In this work, we exhaust all the spin-space symmetries, which fully characterize collinear, non-collinear, commensurate, and incommensurate spiral magnetism, and investigate enrich…
Anderson Critical Metal Phase in Trivial States Protected by Average Magnetic Crystalline Symmetry
Fa-Jie Wang, Zhen-Yu Xiao, Raquel Queiroz +3
Transitions between distinct obstructed atomic insulators (OAIs) protected by crystalline symmetries, where electrons form molecular orbitals centering away from the atom positions…
TBG as Topological Heavy Fermion: II. Analytical approximations of the model parameters
Dumitru Călugăru, Maksim Borovkov, Liam L. H. Lau +3
The recently-introduced Topological Heavy Fermion (THF) model [Phys. Rev. Lett. 129, 047601] of twisted bilayer graphene (TBG) aims to reconcile the quantum-dot-like electronic str…
