Universal scaling of finite-temperature quantum adiabaticity in driven many-body systems
Li-Ying Chou, Jyong-Hao Chen
Establishing quantitative adiabaticity criteria at finite temperature remains substantially less developed than in the pure-state setting, even though realistic quantum systems are…
Quantum adiabaticity in many-body systems and almost-orthogonality in complementary subspace
Jyong-Hao Chen, Vadim Cheianov
We investigate why, in quantum many-body systems, the adiabatic fidelity and the overlap between the initial state and instantaneous ground states often yield nearly identical valu…
Lower bounds for adiabatic quantum algorithms by quantum speed limits
Jyong-Hao Chen
We introduce a simple framework for estimating lower bounds on the runtime of a broad class of adiabatic quantum algorithms. The central formula consists of calculating the varianc…
Bounds on quantum adiabaticity in driven many-body systems from generalized orthogonality catastrophe and quantum speed limit
Jyong-Hao Chen, Vadim Cheianov
We provide two inequalities for estimating adiabatic fidelity in terms of two other more handily calculated quantities, i.e., generalized orthogonality catastrophe and quantum spee…
Stability against contact interactions of a topological superconductor in two-dimensional space protected by time-reversal and reflection symmetries
Ömer M. Aksoy, Jyong-Hao Chen, Shinsei Ryu +2
We study the stability of topological crystalline superconductors in the symmetry class DIIIR and in two-dimensional space when perturbed by quartic contact interactions. It is kno…
Model of spin liquids with and without time-reversal symmetry
Jyong-Hao Chen, Christopher Mudry, Claudio Chamon +1
We study a model in (2+1)-dimensional spacetime that is realized by an array of chains, each of which realizes relativistic Majorana fields in (1+1)-dimensional spacetime, coupled…
A model of chiral spin liquids with Abelian and non-Abelian topological phases
Jyong-Hao Chen, Christopher Mudry, Claudio Chamon +1
We present a two-dimensional lattice model for quantum spin-1/2 for which the low-energy limit is governed by four flavors of strongly interacting Majorana fermions. We study this…
Coupled spin-1/2 ladders as microscopic models for non-Abelian chiral spin liquids
Po-Hao Huang, Jyong-Hao Chen, Adrain E. Feiguin +2
We construct a two-dimensional (2D) lattice model that is argued to realize a gapped chiral spin liquid with (Ising) non-Abelian topological order. The building blocks are spin-1/2…
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…
Effect on Higgs Boson Decays from Large Light-Heavy Neutrino Mixing in Seesaw Models
Jyong-Hao Chen, Xiao-Gang He, Jusak Tandean +1
In seesaw models with more than one generation of light and heavy neutrinos, nu and N, respectively, it is possible to have sizable mixing between them for heavy-neutrino masses of…
