Nonlinearity-Inhomogeneity Competition in Discrete-Time Quantum Walks
N. Amaral, A. R. C. Buarque, W. S. Dias
We investigate the interplay between nonlinearity and inhomogeneities in discrete-time quantum walks on one-dimensional lattices. Nonlinear effects are introduced through a Kerr-li…
Boomerang quantum walks
A. R. C. Buarque, W. S. Dias, Ernesto P. Raposo
In this study, we investigate the emergence of the quantum boomerang effect in discrete-time quantum walks (DTQWs) subjected to random phase disorder. Our analysis shows that this…
Managing rogue quantum amplitudes: a control perspective in quantum walks
A. R. C. Buarque, E. P. Raposo
We investigate the emergence of rogue quantum amplitudes in discrete-time quantum walks (DTQWs) influenced by phase disorder. Our study reveals the statistics of occupation probabi…
Discrete-time quantum walk dispersion control through long-range correlations
A. R. C. Buarque, F. S. Passos, W. S. Dias +1
We investigate the evolution dynamics of inhomogeneous discrete-time one-dimensional quantum walks displaying long-range correlations in both space and time. The associated quantum…
Nonlinear flip-flop quantum walks through potential barriers
F. S. Passos, A. R. C. Buarque
The dynamics of nonlinear flip-flop quantum walk with amplitude-dependent phase shifts with pertubing potential barrier is investigated. Through the adjustment between uniform loca…
Rogue waves in quantum lattices with correlated disorder
A. R. C. Buarque, W. S. Dias, G. M. A. Almeida +2
We investigate the outbreak of anomalous quantum wavefunction amplitudes in a one-dimensional tight-binding lattice featuring correlated diagonal disorder. Such rogue-wave-like beh…
