Corner Charge Fluctuation as an Observable for Quantum Geometry and Entanglement in Two-dimensional Insulators
Pok Man Tam, Jonah Herzog-Arbeitman, Jiabin Yu
Measuring bipartite fluctuations of a conserved charge, such as the particle number, is a powerful approach to understanding quantum systems. When the measured region has sharp cor…
Semi-Dirac Fermions in a Topological Metal
Yinming Shao, Seongphill Moon, A. N. Rudenko +14
Topological semimetals with massless Dirac and Weyl fermions represent the forefront of quantum materials research. In two dimensions (2D), a peculiar class of fermions that are ma…
Topological heavy fermions in magnetic field
Keshav Singh, Aaron Chew, Jonah Herzog-Arbeitman +2
The recently introduced topological heavy fermion model (THFM) provides a means for interpreting the low-energy electronic degrees of freedom of the magic angle twisted bilayer gra…
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…
