Transient ordering in the Gross-Pitaevskii lattice subject to an energy quench within the disordered phase
Andrei E. Tarkhov, A. V. Rozhkov, Boris V. Fine
We numerically investigate heating-and-cooling quenches taking place entirely in the non-ordered phase of the discrete Gross-Pitaevskii equation on a three-dimensional cubic lattic…

Extracting Lyapunov exponents from the echo dynamics of Bose-Einstein condensates on a lattice
Andrei E. Tarkhov, Sandro Wimberger, Boris V. Fine
We propose theoretically an experimentally realizable method to demonstrate the Lyapunov instability and to extract the value of the largest Lyapunov exponent for a chaotic many-pa…
