Dynamical phase diagram of a quantum Ising chain with long-range interactions

Piccitto, Giulia (avtor), Žunkovič, Bojan (avtor), Silva, Alessandro (avtor)

We investigate the effect of short-range correlations on the dynamical phase diagram of quantum many-body systems with long-range interactions. Focusing on Ising spin chains with power-law decaying interactions and accounting for short-range correlations by a cluster mean field theory we show that short-range correlations are responsible for the emergence of a chaotic dynamical region. Analyzing the fine details of the phase diagram, we show that the resulting chaotic dynamics bears close analogies with that of a tossed coin.
