Is efficiency of classical simulations of quantum dynamics related to integrability?
Tomaz Prosen, Marko Znidaric
Efficiency of time-evolution of quantum observables, and thermal states of quenched hamiltonians, is studied using time-dependent density matrix renormalization group method in a f…
Dynamics of Loschmidt echoes and fidelity decay
Thomas Gorin, Tomaz Prosen, Thomas H. Seligman +1
Fidelity serves as a benchmark for the relieability in quantum information processes, and has recently atracted much interest as a measure of the susceptibility of dynamics to pert…
First verification of generic fidelity recovery in a dynamical system
Carlos Pineda, Rudi Schaefer, Tomaz Prosen +1
We study the time evolution of fidelity in a dynamical many body system, namely a kicked Ising model, modified to allow for a time reversal invariance breaking. We find good agreem…
High order non-unitary split-step decomposition of unitary operators
Tomaz Prosen, Iztok Pizorn
We propose a high order numerical decomposition of exponentials of hermitean operators in terms of a product of exponentials of simple terms, following an idea which has been pione…
Value statistics of chaotic Wigner function
Martin Horvat, Tomaz Prosen
We study Wigner function value statistics of classically chaotic quantum maps on compact 2D phase space. We show that the Wigner function statistics of a random state is a Gaussian…
Wigner function statistics in classically chaotic systems
Martin Horvat, Tomaz Prosen
We have studied statistical properties of the values of the Wigner function W(x) of 1D quantum maps on compact 2D phase space of finite area V. For this purpose we have defined a W…
