Quantum Corrections to Fidelity Decay in Chaotic Systems
Boris Gutkin, Daniel Waltner, Martha Gutierrez +2
By considering correlations between classical orbits we derive semiclassical expressions for the decay of the quantum fidelity amplitude for classically chaotic quantum systems, as…
Semiclassical Theory for Decay and Fragmentation Processes in Chaotic Quantum Systems
Martha Gutierrez, Daniel Waltner, Jack Kuipers +1
We consider quantum decay and photofragmentation processes in open chaotic systems in the semiclassical limit. We devise a semiclassical approach which allows us to consistently ca…
Semiclassical Mechanism for the Quantum Decay in Open Chaotic Systems
Daniel Waltner, Martha Gutierrez, Arseni Goussev +1
We address the decay in open chaotic quantum systems and calculate semiclassical corrections to the classical exponential decay. We confirm random matrix predictions and, going bey…
