The distinctive electronic properties of quasicrystals stem from their long-range structural
order, with invariance under rotations and under discrete scale change, but without …

In this work we build a gauge model based on the SU (3) c⊗ SU (3) L⊗ U (1) N symmetry
with heavy neutrinos and show that we can have two weakly interacting cold dark matter …

A detailed and general study of the fermionic structure of the 331 models with β arbitrary is
carried out based on the criterion of cancellation of anomalies. We consider models with an …

We study the minimal set of Higgs scalars, for models based on the local gauge group SU
(3) c⊗ SU (3) L⊗ U (1) X, which do not contain particles with exotic electric charges. We …

A complete study of the Higgs sector of the SU (3) c⊗ SU (3) L⊗ U (1) X model is carried out,
obtaining all possible cases of vacuum expectation values that permit the spontaneous …

In the context of the 331 models, we consider constraints on the extra neutral boson Z′
predicted by the model, where three different quark family assignments are identified. Using …

We propose and analyze a nanoengineered vortex array in a thin-film type-II superconductor
as a magnetic lattice for ultracold atoms. This proposal addresses several of the key …

Six different models, straightforward extensions of the standard model to of SU (3) c⊗ SU (3)
L⊗ U (1) X, which do not contain particles with exotic electric charges are presented. Two of …

A bstract Models based on the extended SU (3) C× SU (3) L× U (1) X (331) gauge group
usually follow a common pattern: two families of left-handed quarks are placed in anti-triplet …

A bstract We propose an extension of the 3-3-1 model with an additional symmetry
group\({Z} _2\times {Z} _4\times\mathrm {U}{(1)} _ {L_g}\) and an extended scalar sector. To …
