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…
Semi-classical wave packet dynamics in non-uniform electric fields
Matthew F. Lapa, Taylor L. Hughes
We study the semi-classical theory of wave packet dynamics in crystalline solids extended to include the effects of a non-uniform electric field. In particular, we derive a correct…
Revisiting (higher order and crystalline) topology in old models of lead telluride
Iñigo Robredo, Maia G. Vergniory, Barry Bradlyn
In this work, we revisit the model of PbTe presented in [E. Fradkin, E. Dagotto, and D. Boyanovsky, Phys. Rev. Lett. 57, 2967 (1986)]. We show that the low energy theory of this mo…
Quasinormal Modes and Hawking-Unruh effect in Quantum Hall Systems: Lessons from Black Hole Phenomena
Suraj S. Hegde, Varsha Subramanyan, Barry Bradlyn +1
In this work, we propose the quantum Hall system as a platform for exploring black hole phenomena. By exhibiting deep rooted commonalities between lowest Landau level and spacetime…
Quantum Critical Diffusion and Thermodynamics in Lifshitz Holography
Brandon W. Langley, Philip W. Phillips
We present the full charge and energy diffusion constants for the Einstein-Maxwell dilaton (EMD) action for Lifshitz spacetime characterized by a dynamical critical exponent . T…
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…
Chiral Topological Semimetal with Multifold Band Crossings and Long Fermi arcs
Niels B. M. Schröter, Ding Pei, Maia G. Vergniory +14
Topological semimetals in crystals with a chiral structure (which possess a handedness due to a lack of mirror and inversion symmetries) are expected to display numerous exotic phy…
A flexible high-performance simulator for verifying and benchmarking quantum circuits implemented on real hardware
Benjamin Villalonga, Sergio Boixo, Bron Nelson +4
Here we present qFlex, a flexible tensor network based quantum circuit simulator. qFlex can compute both exact amplitudes, essential for the verification of the quantum hardware, a…
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,…
Viscoelastic response of quantum Hall fluids in a tilted field
Bendeguz Offertaler, Barry Bradlyn
In this paper, we examine the viscoelastic properties of integer quantum Hall (IQH) states in a tilted magnetic field. In particular, we explore to what extent the tilted-field sys…
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…
Identifying materials with charge-spin physics using charge-spin susceptibility computed from first principles
J. N. B. Rodrigues, Lucas K. Wagner
The authors present a quantity termed charge-spin susceptibility, which measures the charge response to spin degrees of freedom in strongly correlated materials. This quantity is s…
Landau quantization of nearly degenerate bands, and full symmetry classification of avoided Landau-level crossings
Chong Wang, Wenhui Duan, Leonid Glazman +1
Semiclassical quantization rules compactly describe the energy dispersion of Landau levels, and are predictive of quantum oscillations in transport and thermodynamic quantities. Su…
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.…
Nernst Thermopower of Time-Reversal Breaking Type-II Weyl Semimetals
Robert C. McKay, Timothy M. McCormick, Nandini Trivedi
Weyl semimetals host linear energy dispersions around Weyl nodes, as well as monopoles of Berry curvature in momentum space around these points. These features give rise to unique…
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…
