Three-Dimensional Real Space Invariants, Obstructed Atomic Insulators and A New Principle for Active Catalytic Sites
Yuanfeng Xu, Luis Elcoro, Guowei Li +7
Topologically trivial insulators come in two kinds: atomic, where the Wannier charge centers (WCCs) are localized on the atoms, and obstructed atomic, where the WCCs are located aw…
Higher-Order Topological Superconductivity in Twisted Bilayer Graphene
Aaron Chew, Yijie Wang, B. Andrei Bernevig +1
We show that introducing spin-singlet or spin-triplet superconductivity into twisted bilayer graphene induces higher-order topological superconductivity. -protected corner…
Filling-Enforced Obstructed Atomic Insulators
Yuanfeng Xu, Luis Elcoro, Zhi-Da Song +6
Topological band theory has achieved great success in the high-throughput search for topological band structures both in paramagnetic and magnetic crystal materials. However, a sig…
Efficient Method for Prediction of Meta-stable/Ground Multipolar Ordered States and its Application in Monolayer -\ce{RuX3} (X=Cl,I)
Wen-Xuan Qiu, Jin-Yu Zou, Ai-Yun Luo +5
Exotic high-rank multipolar order parameters have been found to be unexpectedly active in more and more correlated materials in recent years. Such multipoles are usually dubbed as…
TSTG I: Single-Particle and Many-Body Hamiltonians and Hidden Non-local Symmetries of Trilayer Moiré Systems with and without Displacement Field
Dumitru Călugăru, Fang Xie, Zhi-Da Song +3
We derive the Hamiltonian for trilayer moiré systems with the Coulomb interaction projected onto the bands near the charge neutrality point. Motivated by the latest experimental re…
Fragile topology in line-graph lattices with two, three, or four gapped flat bands
Christie S. Chiu, Da-Shuai Ma, Zhi-Da Song +2
The geometric properties of a lattice can have profound consequences on its band spectrum. For example, symmetry constraints and geometric frustration can give rise to topologicial…
