M-theory and Hypercharge
We discuss the possibility that the electro-weak and strong interactions arise as the low energy effective description of branes in M-theory. As a step towards constructing such a model we show how one can naturally obtain SU(N 1) × SU(N 2) × U(1) gauge theories from branes, including matter in the bi-fundamental representation of SU(N 1) × SU(N 2) which are fractionally charged under U(1).
متن کاملUnderstanding Hydrogen Adsorption in MIL-47-M (M = V and Fe) through Density Functional Theory
The present paper aims to investigate the role of open metal site metal-organic frameworks (MOFs) on hydrogen adsorptivity using periodic boundary condition (PBC) density functional theory (DFT). Hence, MIL-47-M (M = V and Fe) were selected and one hydrogen molecule adsorptivity was calculated in different orientations on them. Four different chemical sites were identified in every cluster sect...
متن کاملDual Electroweak, Hyper-strong and Hypercharge Models
This paper discusses some details of Vachaspati’s particle-monopole correspondence and their relation to a dual standard model. We show that contained within his correspondence are several sub-correspondences relating to electroweak, strong and hypercharge interactions. Associated with each of these we propose an analogous dual model; the use of these being to examine in isolation specific feat...
متن کاملSupergravity and M-Theory†
Supergravity provides the effective field theories for string compactifications. The deformation of the maximal supergravities by non-abelian gauge interactions is only possible for a restricted class of charges. Generically these ‘gaugings’ involve a hierarchy of p-form fields which belong to specific representations of the duality group. The group-theoretical structure of this p-form hierarch...
متن کاملTime and M-theory
We review our recent proposal for a background independent formulation of a holographic theory of quantum gravity. The present review incorporates the necessary background material on geometry of canonical quantum theory, holography and spacetime thermodynamics, Matrix theory, as well as our specific proposal for a dynamical theory of geometric quantum mechanics, as applied to Matrix theory. At...
