Fractal behaviour in the O(3) model
Christou, Chris; Diakonos, Fotis K.; Panagopoulos, Haralambos G. (1995)We study domain formation in the two-dimensional O(3) model near criticality. The fractal dimension of these domains is determined with good statistical accuracy. © 1995.

Nonperturbative treatment of the N-body system with dynamical mesons
Alexandrou, Constantia; Diakonos, Fotis K. (1995)The variational approach, used by Feynman in the study of the polaron problem, is generalized to treat a system of N non-relativistic particles interacting with scalar and vector mesons. After integrating out the meson ...

Two-layer model for photomodulated thermoreflectance of semiconductor wafers
Christofides, Constantinos; Diakonos, Fotis K.; Seas, Antonios; Christou, Chris; Nestoros, Marios; Mandelis, Andreas (1996)A complete theoretical analysis of the laser photomodulated thermoreflectance signal from a two-layer semiconducting wafer is presented. It is shown that the electronic and thermal properties of a thin surface layer may ...
