The one-loop effective potential of the SU(5) model is investigated both in high and low temperature approximation. We find the regions of values of coupling constants and temperatures where the SU(5), the SU(4)×U(1) and the SU(3)×SU(2)×U(1) symmetric stat ...
The effective potential of the scalar field in the SU(5) model has extrema with symmetry:SU(5), SU(4)×U(1), SU(3)×SU(2)×U(1), SU(3)×[U(1)]2, [SU(2)]2×[U(1)]2. In our recent paper it was shown that the SU(4)×U(1) phase as well as SU(3)×SU(2)×U(1) phase were ...
We give a self-contained discussion of recent progress in computing the non-perturbative effects of small non-holomorphic soft supersymmetry breaking, including a simple new derivation of these results based on an anomaly-free gauged U(1)(R) background. We ...
In a molecular semiconductor, a charged molecule experiences a lattice relaxation which reorganizes it into a cation or an anion-radical. This species is not, in general, a polaron. By using calculations of the geometry and the electronic structure both ab ...
The role of the confinement potential symmetry on the electronic and optical properties of quantum mires is systematically studied. In a wide class of quantum mires with mirror symmetry we evidence a new set of optical transitions resulting both from band ...
We study the consistency of orbifold field theories and clarify to what extent the condition of having an anomaly-free spectrum of zero modes is sufficient to guarantee it. Preservation of gauge invariance at the quantum level is possible, although at the ...
We consider strongly coupled supersymmetric gauge theories softly broken by the addition of gaugino masses m(lambda) and (non-holomorphic) scalar masses m(2), taken to be small relative to the dynamical scale Lambda. For theories with a weakly coupled dual ...
