Topological many-body scar states in dimensions 1, 2, and 3
Seulgi Ok, Kenny Choo, Christopher Mudry +3
We propose an exact construction for atypical excited states of a class of non-integrable quantum many-body Hamiltonians in one dimension (1D), two dimensions (2D), and three dimen…
Spin-directed network model for the surface states of weak three-dimensional topological insulators
Hideaki Obuse, Shinsei Ryu, Akira Furusaki +1
A two-dimensional spin-directed network model is constructed that describes the combined effects of dimerization and disorder for the surface states of a weak…
Topological Hubbard model and its high-temperature quantum Hall effect
Titus Neupert, Luiz Santos, Shinsei Ryu +2
The quintessential two-dimensional lattice model that describes the competition between the kinetic energy of electrons and their short-range repulsive interactions is the repulsiv…
Using random testing to manage a safe exit from the COVID-19 lockdown
Markus Müller, Peter M. Derlet, Christopher Mudry +1
We argue that frequent sampling of the fraction of infected people (either by random testing or by analysis of sewage water), is central to managing the COVID-19 pandemic because i…
Superconductivity on the surface of topological insulators and in two-dimensional noncentrosymmetric materials
Luiz Santos, Titus Neupert, Claudio Chamon +1
We study the superconducting instabilities of a single species of two-dimensional Rashba-Dirac fermions, as it pertains to the surface of a three-dimensional time-reversal symmetri…
Non-Abelian topological spin liquids from arrays of quantum wires or spin chains
Po-Hao Huang, Jyong-Hao Chen, Pedro R. S. Gomes +3
We construct two-dimensional non-Abelian topologically ordered states by strongly coupling arrays of one-dimensional quantum wires via interactions. In our scheme, all charge degre…
