Symmetric Mode Ansatz: Theory of Magnon Collective Modes in Chern Insulators
Miguel Gonçalves, Jonah Herzog-Arbeitman, Juan Felipe Mendez-Valderrama +3
Moiré materials host integer and fractional Chern insulators (FCIs) where time-reversal is broken spontaneously by flat band ferromagnetism. In twisted MoTe2, unlike in quantum Hal…
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…
Revisiting flat band superconductivity: dependence on minimal quantum metric and band touchings
Kukka-Emilia Huhtinen, Jonah Herzog-Arbeitman, Aaron Chew +2
A critical result in superconductivity is that flat bands, though dispersionless, can still host nonzero superfluid weight due to quantum geometry. We show that the derivation of t…
Reentrant Correlated Insulators in Twisted Bilayer Graphene at 25T ( Flux)
Jonah Herzog-Arbeitman, Aaron Chew, Dmitri K. Efetov +1
Twisted bilayer graphene (TBG) is remarkable for its topological flat bands, which drive strongly-interacting physics at integer fillings, and its simple theoretical description fa…
Absence of superdiffusion in certain random spin models
Pieter W. Claeys, Austen Lamacraft, Jonah Herzog-Arbeitman
The dynamics of spin at finite temperature in the spin-1/2 Heisenberg chain was found to be superdiffusive in numerous recent numerical and experimental studies. Theoretical approa…
Superfluid weight bounds from symmetry and quantum geometry in flat bands
Jonah Herzog-Arbeitman, Valerio Peri, Frank Schindler +2
Flat-band superconductivity has theoretically demonstrated the importance of band topology to correlated phases. In two dimensions, the superfluid weight, which determines the crit…
