Critical Properties of the Abelian Higgs Model.: A Monte Carlo Study
(Dr. ingeniøravhandling, 0809-103X; 2002:27, Doctoral thesis, 2002)We have studied various aspects of the critical properties of the Abelian Higgs model. The initial motivation to study this model is its relation to superconductivity, but the results extend beyond the realms of ... -
Statistical Thermodynamics of Proteins
(Dr. ingeniøravhandling, 0809-103X; 2002:26, Doctoral thesis, 2002)The subject of this thesis is to formulate effective energy expressions (Hamiltonians) of proteins and protein related systems. By use of equilibrium statistical mechanics we calculate thermodynamical functions, whereupon ... -
