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 met…
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…
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…
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…
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…
