Thomas Norman Dam.

During his studies, Thomas Norman Dam investigated models describing a physical system coupled to a field of bosons. This class of models is rather large and contains models for a two-level system (a qubit) interacting with light as well as models for a particle in a Bose-Einstein condensate. The results obtained by Thomas are precise mathematical answers to fundamental questions about these models. Among other things, the thesis contains rigorously proven results on existence and regularity of ground states, ultraviolet renormalization and the behaviour of certain models when the physical system is strongly coupled to the field.

The PhD degree was completed at the Department of Mathematics, Science and Technology, Aarhus University.
