Reflection and time reversal symmetry enriched topological phases of matter: path integrals, non-orientable manifolds, and anomalies
Maissam Barkeshli, Parsa Bonderson, Chao-Ming Jian +2
We study symmetry-enriched topological (SET) phases in 2+1 space-time dimensions with spatial reflection and/or time-reversal symmetries. We provide a systematic construction of a…
Many-body localization in incommensurate models with a mobility edge
Dong-Ling Deng, Sriram Ganeshan, Xiaopeng Li +3
We review the physics of many-body localization in models with incommensurate potentials. In particular, we consider one-dimensional quasiperiodic models with single-particle mobil…
Light-induced fractional quantum Hall phases in graphene
Areg Ghazaryan, Tobias Graß, Michael J. Gullans +2
We show how to realize two-component fractional quantum Hall phases in monolayer graphene by optically driving the system. A laser is tuned into resonance between two Landau levels…
Dynamic zero modes of Dirac fermions and competing singlet phases of antiferromagnetic order
Pallab Goswami, Qimiao Si
In quantum spin systems, singlet phases often develop in the vicinity of an antiferromagnetic order. Typical settings for such problems arise when itinerant fermions are also prese…
Topological exciton Fermi surfaces in two-component fractional quantized Hall insulators
Maissam Barkeshli, Chetan Nayak, Zlatko Papić +2
A wide variety of two-dimensional electron systems (2DES) allow for independent control of the total and relative charge density of two-component fractional quantum Hall (FQH) stat…
Interacting Weyl fermions: Phases, phase transitions and global phase diagram
Bitan Roy, Pallab Goswami, Vladimir Juricic
We study the effects of short-range interactions on a generalized three-dimensional Weyl semimetal, where the band touching points act as the (anti)monopoles of Abelian Berry curva…
Filling-enforced Kondo semimetals in two-dimensional non-symmorphic crystals
J. H. Pixley, SungBin Lee, B. Brandom +1
We study the competition between Kondo screening and frustrated magnetism on the non-symmorphic Shastry-Sutherland Kondo lattice at a filling of two conduction electrons per unit c…
Topological spin liquids in the ruby lattice with anisotropic Kitaev interactions
Saeed S. Jahromi, Mehdi Kargarian, S. Farhad Masoudi +1
The ruby lattice is a four-valent lattice interpolating between honeycomb and triangular lattices. In this work we investigate the topological spin-liquid phases of a spin Hamilton…
Kondo insulator SmB6 under strain: surface dominated conduction near room temperature
A. Stern, M. Dzero, V. M. Galitski +2
SmB6 is a strongly correlated mixed-valence Kondo insulator with a newly discovered surface state, proposed to be of non-trivial topological origin. However, the surface state domi…
Topological spin ordering via Chern-Simons superconductivity
Tigran A. Sedrakyan, Victor M. Galitski, Alex Kamenev
We use the Chern-Simons (CS) fermion representation of s =1/2 spin operators to construct topological, long-range magnetically ordered states of interacting two-dimensional (2D) qu…
Exactly soluble model of boundary degeneracy
Sriram Ganeshan, Alexey V. Gorshkov, Victor Gurarie +1
We investigate the topological degeneracy that can be realized in Abelian fractional quantum spin Hall states with multiply connected gapped boundaries. Such a topological degenera…
Charge superconductivity and topological degeneracies without localized zero modes in bilayer fractional quantum Hall states
Maissam Barkeshli
It has been recently shown that non-Abelian defects with localized parafermion zero modes can arise in conventional Abelian fractional quantum Hall (FQH) states. Here we propose an…
Critical local moment fluctuations and enhanced pairing correlations in a cluster Anderson model
Ang Cai, J. H. Pixley, Kevin Ingersent +1
The appearance of unconventional superconductivity near heavy-fermion quantum critical points (QCPs) motivates investigation of pairing correlations close to a ``beyond Landau'' Ko…
The enigmatic 12/5 fractional quantum Hall effect
Kiryl Pakrouski, Matthias Troyer, Yang-Le Wu +2
We numerically study the fractional quantum Hall effect at filling factors and 13/5 (the particle-hole conjugate of 12/5) in high-quality two-dimensional GaAs heterostruct…
Amperean Pairing at the Surface of Topological Insulators
Mehdi Kargarian, Dmitry K. Efimkin, Victor Galitski
The surface of a 3D topological insulator is described by a helical electron state with the electron's spin and momentum locked together. We show that in the presence of ferromagne…
Competing orders and topology in the global phase diagram of pyrochlore iridates
Pallab Goswami, Bitan Roy, Sankar Das Sarma
Strong electronic interactions and spin orbit coupling can be conducive for realizing novel broken symmetry phases supporting quasiparticles with nontrivial band topology. 227 pyro…
Modular transformations through sequences of topological charge projections
Maissam Barkeshli, Michael Freedman
The ground state subspace of a topological phase of matter forms a representation of the mapping class group of the space on which the state is defined. We show that elements of th…
