Level Repulsion and Exceptional Points, of exceptional points the full matrix problem behaves locally like a two dimensional problem. The significance of the exceptional points for the non-linear system of differential equations which determine the energy levels and state vectors as functions of λ is discussed.

Dissipation and Noise in Quantum Mechanics,bath. The Markov property, however, can only be introduced by assumption. Here a specific soluble model is described, in which this assumption can be tested. It appears that the interaction must be weak, and that the temperature must be so high that the interaction is virtually classical.

Coherent and Incoherent Dynamics in a Periodically Driven Bistable System,rical analysis of time evolution and spectrum, based on the Floquet formalism. In the deep quantal regime, we find coherent modifications of tunneling, including its complete suppression. In the semiclassical regime of the conservative system, the dynamics is dominated by the competition of tunnelin

Stochastic Representation of Quantum Dynamics,mpts to make Feynman’s sum over paths mathematically rigorous. An approach suggested by Gelfand and Yaglom to use the propagation kernel in order to construct a complex measure appeared wrong . Another approach based on a Fourier transform suggested first by Ito and developed by Albeverio

Dissipation and Noise in Quantum Mechanics,on for the evolution of the density matrix. In order to obtain the specific form for a given system it is necessary to include the interaction with a bath. The Markov property, however, can only be introduced by assumption. Here a specific soluble model is described, in which this assumption can be
