Topological speckles
Yure M. I. A. Rodrigues, Matheus F. V. Oliveira, Andre M. C. Souza +3
The time evolution of a topological Su-Schrieffer-Heeger chain is analyzed through the statistics of speckle patterns. The emergence of topological edge states dramatically affects…
Non-Rayleigh signal of interacting quantum particles
M. F. V. Oliveira, F. A. B. F. de Moura, A. M. C. Souza +2
The dynamics of two interacting quantum particles on a weakly disordered chain is investigated. Spatial quantum interference between them is characterized through the statistics of…
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…
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…
Localization properties and high-fidelity state transfer in electronic hopping models with correlated disorder
Guilherme M. A. Almeida, Caio V. C. Mendes, Marcelo L. Lyra +1
We investigate a tight-binding electronic chain featuring diagonal and off-diagonal disorder, these being modelled through the long-range-correlated fractional Brownian motion. Par…
Entanglement generation between distant parties via disordered spin chains
Guilherme M. A. Almeida, Francisco A. B. F. de Moura, Marcelo L. Lyra
We study the emergence of bipartite entanglement between a pair of spins weakly connected to the ends of a linear disordered spin-1/2 channel. We analyze how their concurrence…
High-fidelity state transfer through long-range correlated disordered quantum channels
Guilherme M. A. Almeida, Francisco A. B. F. de Moura, Marcelo L. Lyra
We study quantum-state transfer in spin- chains where both communicating spins are weakly coupled to a channel featuring disordered on-site magnetic fields. Fluctuations…
Quantum entanglement and drifting generated by an AC field resonant with frequency-doubled Bloch oscillations of correlated particles
W. S. Dias, F. A. B. F. de Moura, M. L. Lyra
We show that initially localized and uncorrelated two-particles quantum wavepackets evolving in a one-dimensional discrete lattice become strongly entangled while drifting under th…
Wave packet dynamics in chains with delayed electronic nonlinear response
F. A. B. F. de Moura, Iram Gleria, I. F. dos Santos +1
We study the dynamics of one electron wave packet in a chain with a non-adiabatic electron-phonon interaction. The electron-phonon coupling is taken into account in the time-depend…
Bloch-like oscillations in a one-dimensional lattice with long-range correlated disorder
F. Domínguez-Adame, V. A. Malyshev, F. A. B. F. de Moura +1
We study the dynamics of an electron subjected to a uniform electric field within a tight-binding model with long-range-correlated diagonal disorder. The random distribution of sit…
Convergence to the critical attractor of dissipative maps: Log-periodic oscillations, fractality and nonextensivity
F. A. B. F. de Moura, U. Tirnakli, M. L. Lyra
For a family of logistic-like maps, we investigate the rate of convergence to the critical attractor when an ensemble of initial conditions is uniformly spread over the entire phas…
