Emergent from half-filled flat Chern bands

XY Song, H Goldman, L Fu - Physical Review B, 2023 - APS
Recently, two-dimensional Dirac materials patterned with a superlattice structure have
emerged as a rich platform for exploring correlated and topological quantum matter. In this …

Dirac composite fermions and emergent reflection symmetry about even-denominator filling fractions

H Goldman, E Fradkin - Physical Review B, 2018 - APS
Motivated by the appearance of a “reflection symmetry” in transport experiments and the
absence of statistical periodicity in relativistic quantum field theories, we propose a series of …

N Myerson-Jain, CM Jian, C Xu - arXiv preprint arXiv:2311.16250, 2023 - arxiv.org
Recent experimental observations of the fractional quantum anomalous Hall effect in
spin/valley polarized moir\'{e} systems call for a more expansive theoretical exploration of …

Interaction-induced metallicity in a two-dimensional disordered non-Fermi liquid

PA Nosov, IS Burmistrov, S Raghu - Physical Review Letters, 2020 - APS
The interplay of interactions and disorder in two-dimensional (2D) electron systems has
actively been studied for decades. The paradigmatic approach involves starting with a clean …

Loop models, modular invariance, and three-dimensional bosonization

H Goldman, E Fradkin - Physical Review B, 2018 - APS
We consider a family of quantum loop models in 2+ 1 spacetime dimensions with marginally
long-ranged and statistical interactions mediated by a U (1) gauge field, both purely in 2+ 1 …

Landau-Ginzburg theories of non-Abelian quantum Hall states from non-Abelian bosonization

H Goldman, R Sohal, E Fradkin - Physical Review B, 2019 - APS
It is an important open problem to understand the landscape of non-Abelian fractional
quantum Hall phases which can be obtained starting from physically motivated theories of …

[HTML][HTML] Random-mass disorder in the critical Gross-Neveu-Yukawa models

H Yerzhakov, J Maciejko - Nuclear Physics B, 2021 - Elsevier
An important yet largely unsolved problem in the statistical mechanics of disordered
quantum systems is to understand how quenched disorder affects quantum phase …

Strong-weak Chern-Simons-matter dualities from a lattice construction

JY Chen, M Zimet - Journal of High Energy Physics, 2018 - Springer
A bstract We provide a lattice demonstration of (2+ 1)-dimensional field theory dualities
relating free Dirac or Majorana fermions to strongly-interacting bosonic Chern-Simons …

Gauge field fluctuation corrected QED3 effective action by fermionic particle-vortex duality

WH Hsiao - Journal of High Energy Physics, 2024 - Springer
A bstract We present a non-perturbative framework for incorporating gauge field fluctuations
into effective actions of QED 3 in the infrared using fermionic particle-vortex duality. This …

Interplay of interactions and disorder at the superfluid-insulator transition: A dirty two-dimensional quantum critical point

H Goldman, A Thomson, L Nie, Z Bi - Physical Review B, 2020 - APS
We study the stability of the Wilson-Fisher fixed point of the quantum O (2 N) vector model to
quenched disorder in the large-N limit. While a random mass is strongly relevant at the …
