Large deviations in quantum dynamics and complexity
Xiangyu Cao, Jorge Kurchan
We study three definitions of large deviation in many-body quantum dynamics: (i) via the full distribution of an extensive observable, (ii) via the distribution of measurement outc…
Designs via Free Probability
Michele Fava, Jorge Kurchan, Silvia Pappalardi
Unitary Designs have become a vital tool for investigating pseudorandomness since they approximate the statistics of the uniform Haar ensemble. Despite their central role in quantu…
Out-of-time-order correlator in weakly perturbed integrable systems
Tomer Goldfriend, Jorge Kurchan
Classical quasi-integrable systems are known to have Lyapunov times much shorter than their ergodicity time, but the situation for their quantum counterparts is less well understoo…
Quasi-integrable systems are slow to thermalize but may be good scramblers
Tomer Goldfriend, Jorge Kurchan
Classical quasi-integrable systems are known to have Lyapunov times much shorter than their ergodicity time -- the most clear example being the Solar System -- but the situation fo…
Energy gaps in quantum first-order mean-field-like transitions: The problems that quantum annealing cannot solve
T. Jorg, F. Krzakala, J. Kurchan +2
We study first-order quantum phase transitions in models where the mean-field traitment is exact, and the exponentially fast closure of the energy gap with the system size at the t…
Quantum Annealing of Hard Problems
Thomas Jorg, Florent Krzakala, Jorge Kurchan +1
Quantum annealing is analogous to simulated annealing with a tunneling mechanism substituting for thermal activation. Its performance has been tested in numerical simulation with m…
