Anderson Localization: A Floquet operator Krylov space perspective
Hsiu-Chung Yeh, Aditi Mitra
The problem of Anderson localization, as well as the single particle localization-delocalizaton transition of the Aubry-André model, is studied employing operator Krylov space meth…
Floquet operator dynamics and orthogonal polynomials on the unit circle
Hsiu-Chung Yeh, Aditi Mitra
Operator spreading under stroboscopic time evolution due to a unitary is studied. An operator Krylov space is constructed and related to orthogonal polynomials on a unit circle (OP…
Gapless Floquet topology
Gabriel Cardoso, Hsiu-Chung Yeh, Leonid Korneev +2
Symmetry-protected topological (SPT) phases in insulators and superconductors are known for their robust edge modes, linked to bulk invariants through the bulk-boundary corresponde…
Moment method and continued fraction expansion in Floquet Operator Krylov Space
Hsiu-Chung Yeh, Aditi Mitra
Recursion methods such as Krylov techniques map complex dynamics to an effective non-interacting problem in one dimension. For example, the operator Krylov space for Floquet dynami…
Floquet Product Mode
Hsiu-Chung Yeh, Achim Rosch, Aditi Mitra
Results are presented for the dynamics of edge modes in interacting Floquet Ising chains. It is shown that in addition to the quasi-stable and edge modes, a third long live…
Strong zero modes in integrable quantum circuits
Eric Vernier, Hsiu-Chung Yeh, Lorenzo Piroli +1
It is a classic result that certain interacting integrable spin chains host robust edge modes known as strong zero modes (SZMs). In this work, we extend this result to the Floquet…
A Universal Model of Floquet Operator Krylov Space
Hsiu-Chung Yeh, Aditi Mitra
It is shown that the stroboscopic time-evolution under a Floquet unitary, in any spatial dimension, and of any Hermitian operator, can be mapped to an operator Krylov space which i…
Slowly decaying zero mode in a weakly non-integrable boundary impurity model
Hsiu-Chung Yeh, Gabriel Cardoso, Leonid Korneev +3
The transverse field Ising model (TFIM) on the half-infinite chain possesses an edge zero mode. This work considers an impurity model -- TFIM perturbed by a boundary integrability…
Decay rates of almost strong modes in Floquet spin chains beyond Fermi's Golden Rule
Hsiu-Chung Yeh, Achim Rosch, Aditi Mitra
The stability and dynamics of almost strong zero and modes in weakly non-integrable Floquet spin chains are investigated. Such modes can also be viewed as localized Majorana mo…
Non-integrable Floquet Ising model with duality twisted boundary conditions
Aditi Mitra, Hsiu-Chung Yeh, Fei Yan +1
Results are presented for a Floquet Ising chain with duality twisted boundary conditions, taking into account the role of weak integrability breaking in the form of four-fermion in…
Many-body localization enables iterative quantum optimization
Hanteng Wang, Hsiu-Chung Yeh, Alex Kamenev
We suggest an iterative quantum protocol, allowing to solve optimization problems with a glassy energy landscape. It is based on a periodic cycling around the tricritical point of…
Emptiness Formation in Polytropic Quantum Liquids
Hsiu-Chung Yeh, Dimitri M. Gangardt, Alex Kamenev
We study large deviations in interacting quantum liquids with the polytropic equation of state , where is density and is pressure. By solving hydrodynamic equ…
Emptiness Formation Probability in 1D Bose Liquids
Hsiu-Chung Yeh, Alex Kamenev
We study emptiness formation probability (EFP) in interacting 1D Bose liquids. That is the probability that a snapshot of its ground state reveals exactly zero number of particles…
