Interacting Topological Quantum Chemistry in 2D: Many-body Real Space Invariants
Jonah Herzog-Arbeitman, B. Andrei Bernevig, Zhi-Da Song
The topological phases of non-interacting fermions have been classified by their symmetries, culminating in a modern electronic band theory where wavefunction topology can be obtai…
Spectroscopy of the frustrated quantum antiferromagnet CsCuCl
Adolfo O. Fumega, D. Wong, C. Schulz +2
We investigate the electronic structure of CsCuCl, a material discussed in the framework of a frustrated quantum antiferromagnet, by means of resonant inelastic x-ray scatt…
Dissipative Symmetry-Protected Topological Order
Luan M. Veríssimo, Marcelo L. Lyra, Roman Orus
In this work, we investigate the interplay between dissipation and symmetry-protected topological order. We considered the one-dimensional spin-1 Affleck-Kennedy-Lieb-Tasaki model…
Universal features of entanglement entropy in the honeycomb Hubbard model
Jonathan D'Emidio, Roman Orus, Nicolas Laflorencie +1
The entanglement entropy is a unique probe to reveal universal features of strongly interacting many-body systems. In two or more dimensions these features are subtle, and detectin…
Dramatic Plasmon Response to the Charge-Density-Wave Gap Development in
Zijian Lin, Cuixiang Wang, A. Balassis +8
1T-TiSe2 is one of the most studied charge density wave (CDW) systems, not only because of its peculiar properties related to the CDW transition, but also due to its status as a pr…
Phase diagram of twisted bilayer graphene at filling factor
Fang Xie, Jian Kang, B. Andrei Bernevig +2
We study the correlated insulating phases of twisted bilayer graphene (TBG) in the absence of lattice strain at integer filling . Using the self-consistent Hartree-Fock met…
