First exact Geon found is a non-singular monopole, propagating as a primordial gravitational pp-wave
Nikolaos A. Batakis
Geons are particle-like electrovacua. The concept is well-defined, but it still lacks a proper first example. Emerging as such is a self-confined exact 2-parameter pp-wave non-Dira…
Geons found include non-susy CDM particle and non-singular "Kerr-Newman" models
Nikolaos A. Batakis
The antisoliton-soliton {\cal G}={\cal S_-}\!\vee{\cal S_+} neutral state is a proper geon in a family of stable squashed-S^3\times\IR pp-wave electrovacua along a primordial Q/r^2…
Toward a standard model 2, via Kaluza ansatz 2
Nikolaos A. Batakis
New results and perspectives precipitate from the (modified as) Kaluza ansatz 2 (KA2), whereby, instead of appending Planck-scale () compact SL dimensions to ordinar…
The 4-dimensional Taub string
Nikolaos A. Batakis
The prototype of a Taub string is formed by successive junctions of copies of Taub's space {\cal T}, joined at their null boundaries Σto create the axially-symmetric Bianchi-type-X…
Higgsless EW gauge-boson masses from K-K geometry with torsion
Nikolaos A. Batakis
In the classical Higgsless Kaluza-Klein gauge-theory vacuum, torsion-induced loss of the left-invariance generates a gauge-boson mass t…
General relativity reformed to a genuine Yang-Mills gauge theory for gravity
Nikolaos A. Batakis
The theory of general relativity is reformed to a genuine Yang-Mills gauge theory of the Poincaré group for gravity. Several pathologies of the conventional theory are thus removed…
The gravitational and electroweak interactions unified as a gauge theory of the De Sitter group
Nikolaos A Batakis
The complexified gauging of the de Sitter group gives a unified theory for the electroweak and gravitational interactions. The standard spectrum for the electroweak gauge bosons is…
On certain cosmological relics of the early string dynamics
Nikolaos A Batakis
The tracing of cosmological relics from the early string dynamics may enhance the theory and provide new perspectives on the major cosmological problems. This point is illustrated…
Bianchi-type string cosmology
N. A. Batakis
Bianchi-type string cosmology involves generalizations of the FRW backgrounds with three transitive spacelike Killing symmetries, but without any a priori assumption of isotropy in…
A new class of spatially homogeneous 4D string backgrounds
Nikolaos A. Batakis
A new class of spatially homogeneous 4D string backgrounds, the according to a recent classification, is presented and shown to contain only five generic types. I…
On the Classification of Spatially Homogeneous String Backgrounds
Nikolaos A. Batakis
A classification of all possible spatially homogeneous 4D string backgrounds (HSBs) has been obtained by appropriate ramification of the existing nine Bianchi types of homogeneous…
Anisotropic space-times in homogeneous string cosmology
N. A. Batakis, A. A. Kehagias
The dynamics of the early universe may have been profoundly influenced by spatial anisotropies. A search for such backgrounds in the context of string cosmology has uncovered the e…
