Abstract In these lectures, starting with a review of secondand coherent-state path-integral quantization, we will formulate a quantum field theory of bosonic matter and will study its thermodynamics and correlation functions. We will explore the transition to Bose-Einstein condensation (BEC) of noninteracting bosons. Including interactions, we will study the properties of a superfluid and a ph...

Head: Prof. Igor Muševič Our research program is focused on studying the structure and dynamics of disordered and partially ordered condensed matter at the atomic and molecular levels, with a special emphasis on phase transitions. The purpose of these investigations is to discover the basic laws of physics governing the behavior of these systems, which represent the link between perfectly order...

mass separation ISOL-principle ial. Then these isotopes can be either diffused or implanted into the material under study. The most versatile procedure is ion implantation: Depending on the implantation energy, the concentration of dopants, their lateral and their depth distribution can be controlled easily. Any unwanted co-doping by other elements is only determined by the purity of the ion be...

The comparaison between condensed matter studies using neutrons and photons is a well known subject which can be found in many text books. However the occurence of synchrotron source is strongly changing the situation. Some personal considerations about the possible future evolutions will be given.
