Abstract We study numerically the properties of entanglement two interacting, or noninteracting, particles evolving in a regime quantum chaos Chirikov standard map. Such pairs can be viewed as on Einstein–Podolsky–Rosen chaos. The analysis is done with such tools Loschmidt echo and Poincaré recurrences presence absorption. obtained results show unusual features entropy spectrum Schmidt decomposition their dependence interactions at different regimes.

Poincaré recurrences of DNA sequences.
We analyze the statistical properties of Poincaré recurrences of Homo sapiens, mammalian, and other DNA sequences taken from the Ensembl Genome data base with up to 15 billion base pairs. We show that the probability of Poincaré recurrences decays in an algebraic way with the Poincaré exponent β≈4 even if the oscillatory dependence is well pronounced. The correlations between recurrences decay ...
متن کاملDecoherence and Noise in Loschmidt Echo Experiments
We discuss some recent results concerning the decoherence in controlled quantum open systems within the mathematical setting corresponding to motion reversal experiments (the Loschmidt echo). We compare the case of randomly chosen sequence of unitary dynamical maps with the case of a constant dynamics corresponding to a classically chaotic evolution. The interplay between chaos and decoherence ...
متن کاملLoschmidt echo for a chaotic oscillator.
Chaotic dynamics of a nonlinear oscillator is considered in the semiclassical approximation. The Loschmidt echo as a measure of quantum stability to a time dependent variation is calculated. It is shown that an exponential decay of the Loschmidt echo is due to a Lyapunov exponent and it has a pure classical nature. The Lyapunov regime is observed for a time scale which is of the power law in se...
متن کاملLoschmidt-echo decay from local boundary perturbations.
We investigate the sensitivity of the time evolution of semiclassical wave packets in two-dimensional chaotic billiards with respect to local perturbations of their boundaries. For this purpose, we address, analytically and numerically, the time decay of the Loschmidt echo (LE). We find the LE to decay exponentially in time, with the rate equal to the classical escape rate from an open billiard...
متن کاملLoschmidt echo and the local density of states.
Loschmidt echo (LE) is a measure of reversibility and sensitivity to perturbations of quantum evolutions. For weak perturbations its decay rate is given by the width of the local density of states (LDOS). When the perturbation is strong enough, it has been shown in chaotic systems that its decay is dictated by the classical Lyapunov exponent. However, several recent studies have shown an unexpe...
