Abstract (German)

In this PhD thesis we have been concerned with dissipative and decoherence processes which take place specifically for quantum systems in a dissipative bistable potential. This potential describes a Hamiltonian system whose spectrum is composed by a ladder of levels, grouped as doublets under the potential barrier and being almost equally spaced above it. The system interacts with a thermal ...

Dieses Potential beschreibt ein Hamiltonsystem dessen Spectrum aus gleichförmig verteilten Niveaus besteht, welche unterhalb der Potentialbarriere als Doubletts vorkommen. Das System wechselwirkt mit einer thermischen ...
