Two interacting charged particles in an Aharonov-Bohm ring: Bound state transitions, symmetry breaking, persistent currents, and Berry's phase
Moulopoulos, Konstantinos; Constantinou, Martha G. (2004)By using a Green's function procedure we determine exactly the energy spectrum and the associated eigen-states of a system of two oppositely charged particles interacting through a contact potential and moving in a ...

Two-loop additive mass renormalization with clover fermions and Symanzik improved gluons
Skouroupathis, A.; Constantinou, Martha G.; Panagopoulos, Haralambos G. (2008)We calculate the critical value of the hopping parameter, κc, in lattice QCD, up to two loops in perturbation theory. We employ the Sheikholeslami-Wohlert (clover) improved action for fermions and the Symanzik improved ...
