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…
Nonlinear three-state quantum walks
P. R. N. Falcão, J. P. Mendonça, A. R. C. Buarque +3
The dynamics of a three-state quantum walk with amplitude-dependent phase shifts is investigated. We consider two representative inputs whose linear evolution is known to display e…
Noise correlations behind superdiffusive quantum walks
Graça R. M. de Almeida, N. Amaral, A. R. C. Buarque +1
We study how discrete-time quantum walks behave under short-range correlated noise. By considering noise as a source of inhomogeneity of quantum gates, we introduce a primitive rel…
Rogue waves in discrete-time quantum walks
A. R. C. Buarque, W. S. Dias, F. A. B. F. de Moura +2
Rogue waves are rapid and unpredictable events of exceptional amplitude reported in various fields, such as oceanography and optics, with much of the interest being targeted toward…
