Corner Modes and Ground-State Degeneracy in Models with Gauge-Like Subsystem Symmetries
Julian May-Mann, Taylor L. Hughes
Subsystem symmetries are intermediate between global and gauge symmetries. One can treat these symmetries either like global symmetries that act on subregions of a system, or gauge…
Many-Body Electric Multipole Operators in Extended Systems
William A. Wheeler, Lucas K. Wagner, Taylor L. Hughes
The quantum mechanical position operators, and their products, are not well-defined in systems obeying periodic boundary conditions. Here we extend the work of Resta who developed…
Pair-Density-Wave Order and Paired Fractional Quantum Hall Fluids
Luiz H. Santos, Yuxuan Wang, Eduardo Fradkin
The properties of the isotropic incompressible fractional quantum Hall (FQH) state are described by a paired state of composite fermions in zero (effective) magnetic field,…
Families of Gapped Interfaces Between Fractional Quantum Hall States
Julian May-Mann, Taylor L. Hughes
Some interfaces between two different topologically ordered systems can be gapped. In earlier work it has been shown that such gapped interfaces can themselves be effective one dim…
Disorder induced power-law gaps in an insulator-metal Mott transition
Zhenyu Wang, Yoshinori Okada, Jared O'Neal +11
A correlated material in the vicinity of an insulator-metal transition (IMT) exhibits rich phenomenology and variety of interesting phases. A common avenue to induce IMTs in Mott i…
Pressure-Induced Metal-Insulator Transition in Twisted Bi-layer Graphene
Bikash Padhi, Philip Phillips
Recent experiments [arXiv: 1808.07865] on twisted bilayer graphene (TBLG) show that under hydrostatic pressure, an insulating state at quarter-filling of the moiré superlattice (i.…
Geometric quench in the fractional quantum Hall effect: exact solution in quantum Hall matrix models and comparison with bimetric theory
Matthew F. Lapa, Andrey Gromov, Taylor L. Hughes
We investigate the recently introduced geometric quench protocol for fractional quantum Hall (FQH) states within the framework of exactly solvable quantum Hall matrix models. In th…
Quantization of fractional corner charge in -symmetric higher-order topological crystalline insulators
Wladimir A. Benalcazar, Tianhe Li, Taylor L. Hughes
In the presence of crystalline symmetries, certain topological insulators present a filling anomaly: a mismatch between the number of electrons in an energy band and the number of…
Resonating quantum three-coloring wavefunctions for the kagome quantum antiferromagnet
Hitesh J. Changlani, Sumiran Pujari, Chia-Min Chung +1
Motivated by the recent discovery of a macroscopically degenerate exactly solvable point of the spin- model for on the kagome lattice [H. J. Changlani et al…
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…
Helical spin thermoelectrics controlled by a side-coupled magnetic quantum dot in the quantum spin Hall state
P. Roura-Bas, Liliana. Arrachea, Eduardo Fradkin
We study the thermoelectric response of a device containing a pair of helical edge states contacted at the same temperature and chemical potential and connected to an exter…
Generalized Wen-Zee Terms
Bo Han, Huajia Wang, Peng Ye
Motivated by symmetry-protected topological phases (SPTs) with both spatial symmetry (e.g., lattice rotation) and internal symmetry (e.g., spin rotation), we propose a class of exo…
Higher Order Bosonic Topological Phases in Spin Models
Oleg Dubinkin, Taylor L. Hughes
We discuss an extension of higher order topological phases to include bosonic systems. We present two spin models for a second-order topological phase protected by a global $\mathb…

Jyotisman Sahoo, Dmitrii Kochkov, Bryan K. Clark +1
We investigate the classical phase diagram of the stuffed honeycomb Heisenberg lattice, which consists of a honeycomb lattice with a superimposed triangular lattice formed by sites…
Bosonization of Fermi liquids in a weak magnetic field
Daniel G. Barci, Eduardo Fradkin, Leonardo Ribeiro
Novel controlled non-perturbative techniques are a must in the study of strongly correlated systems, especially near quantum criticality. One of these techniques, bosonization, has…
Hall Viscosity in the Non-Abelian Quantum Hall Matrix Model
Matthew F. Lapa, Carl Turner, Taylor L. Hughes +1
Quantum Hall matrix models are simple, solvable quantum mechanical systems which capture the physics of certain fractional quantum Hall states. Recently, it was shown that the Hall…
Scale-invariance as the cause of the superconducting dome in the cuprates
Zhidong Leong, Kridsanaphong Limtragool, Chandan Setty +1
Recent photoemission spectroscopy measurements (T. J. Reber et al., arXiv:1509.01611) of cuprate superconductors have inferred that the self-energy exhibits critical scaling over a…
Doped Twisted Bilayer Graphene near Magic Angles: Proximity to Wigner Crystallization not Mott Insulation
Bikash Padhi, Chandan Setty, Philip W. Phillips
We devise a model to explain why twisted bi-layer graphene (TBLG) exhibits insulating behavior when charges occupy a unit moiré cell, a feature attributed to Mottness, but…
Symmetry-Protected Topological Interfaces and Entanglement Sequences
Luiz H. Santos, Jennifer Cano, Michael Mulligan +1
Gapped interfaces (and boundaries) of two-dimensional (2D) Abelian topological phases are shown to support a remarkably rich sequence of 1D symmetry-protected topological (SPT) sta…
From gauge to higher gauge models of topological phases
Clement Delcamp, Apoorv Tiwari
We consider exactly solvable models in (3+1)d whose ground states are described by topological lattice gauge theories. Using simplicial arguments, we emphasize how the consistency…

Yago Ferreiros, Eduardo Fradkin
We study the dimensional boson-fermion duality in the presence of background curvature and electromagnetic fields. The main players are, on the one hand, a massive complex $|…
Computational inverse method for constructing spaces of quantum models from wave functions
Eli Chertkov, Bryan K. Clark
Traditional computational methods for studying quantum many-body systems are "forward methods," which take quantum models, i.e., Hamiltonians, as input and produce ground states as…
