Some Aspects of Symmetry Breaking in Unified Weak-Electromagnetic Gauge Theories
… on the role of the Higgs scalars in the spontaneous breakdown of the theory. In Chapter 3, we consider the following question: how can we break the gauge symmetry in such a way that all of the weak vector mesons acquire mass but the photon remains massless? In Chapter 4, in the context of …

Critical Properties of the Emergent Random Solid in Vulcanization/gelation Transition
… wave-length fluctuations associated with the spontaneous breakdown of a (global, continuous) translational symmetry at the transition. These fluctuations are identified with the shear deformations of the emergent random solid, whose shear modulus and elastic free energy are derived utilizing …

Field theoretical methods for strongly correlated electron systems
… which has a spin-gap generated by the spontaneous breakdown of time-reversalsymmetry. This state is known as the Chiral Spin State. We determine conditions for the restoration of time-reversal-symmetry in a bilayer antiferromagnet with an interlayer exchange interaction. We show the …

ΜΗΧΑΝΙΣΜΟΣ HIGGS ΓΙΑ ΑΒΕΛΙΑΝΕΣ ΘΕΩΡΙΕΣ ΒΑΘΜΙΔΑΣ ΣΕ ΧΩΡΟΧΡΟΝΙΚΟ ΠΛΕΓΜΑ
THE OBELIAN HIGGS MODEL IS STUDIED ON A SPACE-TIME LATTICE. THE MODEL EXHIBITS THREE PHASES, NAMELY COULOMB, HIGGS AND CONFINING PHASE. THE COLEMIN-WEINBERG MECHANISM IS SEEN TO OPERATE. THE EFFECTIVE POTENTIAL IS CALCULATED BY COUPLING THE SYSTEM TO EXTERNAL CURRENTS. IN THE HIGGS PHASE THERE …
