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…
Topological Floquet Green's function zeros
Elio J. König, Aditi Mitra
Motivated by recent advances in digital quantum emulation using noisy intermediate-scale quantum (NISQ) devices and an increased interest in topological Green's function zeros in c…
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…
Almost Strong Zero Modes at Finite Temperature
Niklas Tausendpfund, Aditi Mitra, Matteo Rizzi
Interacting fermionic chains exhibit extended regions of topological degeneracy of their ground states as a result of the presence of Majorana or parafermionic zero modes localized…
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…
Duality defect in a deformed transverse-field Ising model
Fei Yan, Robert Konik, Aditi Mitra
Physical quantities with long lifetimes have both theoretical significance in the study of quantum many-body systems and practical implications for quantum technologies. In this ma…
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…
Disorder induced topological phase transition in a driven Majorana chain
Henry Ling, Philip Richard, Saeed Rahmanian Koshkaki +4
We study a periodically driven one dimensional Kitaev model in the presence of disorder. In the clean limit our model exhibits four topological phases corresponding to the existenc…
