Monte-Carlo studies of multi-component Ginzburg-Landau theories with competing interactions

Galteland, Peder Notto (Doctoral thesis at NTNU;2016:214, Doctoral thesis, 2016)

This thesis presents four research papers in the field of condensed-matter theory. Three of the papers make use of large-scale Monte-Carlo simulations to explore various aspects of Bose-Einstein condensates with multiple ...
Symmetry Breaking in ordinary and supersymmetric Models of Quantum Field Theory

Galteland, Peder Notto (Master thesis, 2012)

This thesis will consider two different theories, and apply variational techniquesto each, in order to investigate their true ground states and the possibility ofsymmetry breaking.A scalar field theory is modified by ...
Thermal remixing of phase-separated states in two-component bosonic condensates

Galteland, Peder Notto; Babaev, Egor; Sudbø, Asle (Journal article; Peer reviewed, 2015)

Weconsider a two-component interacting bosonic condensate with dominating intra-species repulsive density–density interactions.Westudy the phase diagram of the system at finite temperature with rotation, using large-scale ...
