Creating anomalous Floquet Chern insulators with magnetic quantum walks

M Sajid, JK Asbóth, D Meschede, RF Werner, A Alberti - Physical Review B, 2019‏ - APS
We propose a realistic scheme to construct anomalous Floquet Chern topological insulators
using spin-1 2 particles carrying out a discrete-time quantum walk in a two-dimensional …

Quantum walks and discrete gauge theories

P Arnault, F Debbasch - Physical Review A, 2016‏ - APS
A particular example is produced to prove that quantum walks can be used to simulate full-
fledged discrete gauge theories. A family of two-dimensional walks is introduced and its …

Quantum walks in external gauge fields

C Cedzich, T Geib, AH Werner… - Journal of Mathematical …, 2019‏ - pubs.aip.org
Describing a particle in an external electromagnetic field is a basic task of quantum
mechanics. The standard scheme for this is known as “minimal coupling” and consists of …

Robustness of topologically protected edge states in quantum walk experiments with neutral atoms

T Groh, S Brakhane, W Alt, D Meschede, JK Asbóth… - Physical Review A, 2016‏ - APS
Discrete-time quantum walks allow Floquet topological insulator materials to be explored
using controllable systems such as ultracold atoms in optical lattices. By numerical …

Electromagnetic lattice gauge invariance in two-dimensional discrete-time quantum walks

I Márquez-Martín, P Arnault, G Di Molfetta, A Pérez - Physical Review A, 2018‏ - APS
Gauge invariance is one of the more important concepts in physics. We discuss this concept
in connection with the unitary evolution of discrete-time quantum walks in one and two …

Discrete-time quantum walk with phase disorder: localization and entanglement entropy

M Zeng, EH Yong - Scientific reports, 2017‏ - nature.com
Quantum Walk (QW) has very different transport properties to its classical counterpart due to
interference effects. Here we study the discrete-time quantum walk (DTQW) with on-site …

Quantum walks with sequential aperiodic jumps

MA Pires, SMD Queirós - Physical Review E, 2020‏ - APS
We analyze a set of discrete-time quantum walks for which the displacements on a chain
follow binary aperiodic jumps according to three paradigmatic sequences: Fibonacci, Thue …

Generalized quantum-classical correspondence for random walks on graphs

M Frigerio, C Benedetti, S Olivares, MGA Paris - Physical Review A, 2021‏ - APS
We introduce a minimal set of physically motivated postulates that the Hamiltonian H of a
continuous-time quantum walk should satisfy in order to properly represent the quantum …

Quantum walks in weak electric fields and Bloch oscillations

P Arnault, B Pepper, A Pérez - Physical Review A, 2020‏ - APS
Bloch oscillations appear when an electric field is superimposed on a quantum particle that
evolves on a lattice with a tight-binding Hamiltonian (TBH), ie, evolves via what we call an …
