Semiclassical Propagation of Wavepackets with Complex Trajectories
We derive a semiclassical approximation for the time evolution of an originally gaussian wave packet in terms of complex trajectories. We also consider additional approximations replacing the complex trajectories by real ones. These yield three different semiclassical formulae involving different real trajectories. One of these formulae is Heller’s thawed gaussian approximation. The other appro...
متن کاملSemiclassical Propagation of Wavepackets with Complex and Real Trajectories
We consider a semiclassical approximation, first derived by Heller and coworkers, for the time evolution of an originally gaussian wave packet in terms of complex trajectories. We also derive additional approximations replacing the complex trajectories by real ones. These yield three different semiclassical formulae involving different real trajectories. One of these formulae is Heller’s thawed...
متن کاملUnstable semiclassical trajectories in tunneling.
Some tunneling phenomena are described, in the semiclassical approximation, by unstable complex trajectories. We develop a systematic procedure to stabilize the trajectories and to calculate the tunneling probability, including both the suppression exponent and prefactor. We find that the instability of tunneling solutions modifies the power-law dependence of the prefactor on Planck's variant a...
متن کاملRelaxational trajectories: global approximations
The paper intends to fill the gap of analytic approximate methods for non-linear spaceindependent dissipative systems equipped with the entropy functional. The key point of the analysis is an upper limiting state in the beginning of the relaxation. Extremal properties of this state are described and explicit estimations are derived. This limiting state is used to construct explicit approximatio...
متن کاملSemiclassical decay of excited string states on leading Regge trajectories.
We study the decay of hadrons based on a semiclassical string model. By including quark mass effects we find that the width to mass ratio Γ/m is an increasing function of m, which increases most rapidly for massive quarks. This is consistent with the available data. The decay probability of hadrons on the leading Regge trajectories is computed taking the effect of the string rotation into accou...
