Effect of pitchfork bifurcations on the spectral statistics of Hamiltonian systems
Marta Gutiérrez, Matthias Brack, Klaus Richter +1
We present a quantitative semiclassical treatment of the effects of bifurcations on the spectral rigidity and the spectral form factor of a Hamiltonian quantum system defined by tw…

Loschmidt echo decay from local boundary perturbations
Arseni Goussev, Klaus Richter
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…
