Coloring in anyon superconductivity
Umang Mehta, Yuto Nakajima, Hart Goldman
The recently observed signatures of superconductivity proximate to a fractional quantum anomalous Hall (FQAH) state in a twisted MoTe bilayer has revitalized interest in quantu…
Extraordinary boundary correlations at deconfined quantum critical points
Hao-Ran Cui, Hart Goldman
Recent years have seen a growing appreciation for the effects of quantum critical fluctuations on gapless boundary degrees of freedom. Here we consider the boundary dynamics of the…
The Sound of Electrons Shattering: Current Noise Composition Laws for Electron Fractionalization
Adarsh S. Patri, Josephine J. Yu, Yi-Ming Wu +2
We develop a theory of the non-equilibrium current response for metallic systems near quantum critical points where electronic quasiparticles fractionalize, such as systems near co…
Thermodynamics of dilute anyon gases from fusion constraints
Yuto Nakajima, Umang Mehta, Hart Goldman
Recent measurements on 2d materials tuning between fractional quantum anomalous Hall phases and a plethora of correlated electronic states call for a detailed understanding of the…
Excitonic quantum criticality: from bilayer graphene to narrow Chern bands
Zhengyan Darius Shi, Hart Goldman, Zhihuan Dong +1
We study a family of excitonic quantum phase transitions describing the evolution of a bilayer metallic state to an inter-layer coherent state where excitons condense. We argue tha…
Emergent QED from half-filled flat Chern bands
Xue-Yang Song, Hart Goldman, Liang Fu
In recent years, two-dimensional Dirac materials patterned with a superlattice structure have emerged as a rich platform for exploring correlated and topological quantum matter. In…
Loop current fluctuations and quantum critical transport
Zhengyan Darius Shi, Dominic V. Else, Hart Goldman +1
We study electrical transport at quantum critical points (QCPs) associated with loop current ordering in a metal, focusing specifically on models of the "Hertz-Millis" type. At the…
Theory of oblique topological insulators
Benjamin Moy, Hart Goldman, Ramanjit Sohal +1
A long-standing problem in the study of topological phases of matter has been to understand the types of fractional topological insulator (FTI) phases possible in 3+1 dimensions. U…
Gifts from anomalies: Exact results for Landau phase transitions in metals
Zhengyan Darius Shi, Hart Goldman, Dominic V. Else +1
Non-Fermi liquid phenomena arise naturally near critical points of Landau ordering transitions in metallic systems, where strong fluctuations of a bosonic order parameter destroy c…
A composite particle construction of the Fibonacci fractional quantum Hall state
Hart Goldman, Ramanjit Sohal, Eduardo Fradkin
The Fibonacci topological order is the simplest platform for a universal topological quantum computer, consisting of a single type of non-Abelian anyon, , with fusion rule $τ\ti…
Non-Abelian Fermionization and the Landscape of Quantum Hall Phases
Hart Goldman, Ramanjit Sohal, Eduardo Fradkin
The recent proposal of non-Abelian boson-fermion dualities in 2+1 dimensions, which morally relate to Chern-Simons-matter theories, presents a new platform fo…
Collusion of Interactions and Disorder at the Superfluid-Insulator Transition: A Dirty 2d Quantum Critical Point
Hart Goldman, Alex Thomson, Laimei Nie +1
We study the stability of the Wilson-Fisher fixed point of the quantum vector model to quenched disorder in the large- limit. While a random mass is strongly re…
Landau-Ginzburg Theories of Non-Abelian Quantum Hall States from Non-Abelian Bosonization
Hart Goldman, Ramanjit Sohal, Eduardo Fradkin
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 Abeli…
Dirac Composite Fermions and Emergent Reflection Symmetry about Even Denominator Filling Fractions
Hart Goldman, Eduardo Fradkin
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 seri…
Loop Models, Modular Invariance, and Three Dimensional Bosonization
Hart Goldman, Eduardo Fradkin
We consider a family of quantum loop models in 2+1 spacetime dimensions with marginally long-ranged and statistical interactions mediated by a U gauge field, both purely in 2+…

We study Dirac fermions in two spatial dimensions (2D) coupled to strongly fluctuating U(1) gauge fields in the presence of quenched disorder. Such systems are dual to theories of…
