چکیده

Non-standard overview on the possible formulation towards a unified model on the lattice is presented. It is based on the generalized gauge theory which is formulated by differential forms and thus expected to fit in a simplicial manifold. We first review suggestive known results towards this direction. As a small step of concrete realization of the program, we propose a lattice Chern-Simons gravity theory which leads to the Chern-Simons gravity in the continuum limit via Ponzano-Regge model. We then summarize the quantization procedure of the generalized gauge theory and apply the formulation to the generalized topological Yang-Mills action with instanton gauge fixing. We find N = 2 super Yang-Mills theory with Dirac-Kähler fermions which are generated from ghosts via twisting mechanism. The Weinberg-Salam model is formulated by the generalized Yang-Mills action which includes Connes’s non-commutative geometry formulation as a particular case. In the end a possible scenario to realize the program is proposed. The formulations given here are by far incomplete towards the final goal yet include hopeful evidences. This summary of the overview is the extended version of the talk given at Nishinomiya-Yukawa memorial symposium (Nishinomiya-city Japan, Nov. 1998). To be published in the Proceedings of 13th Nishinomiya-Yukawa Memorial Symposium, Nishinomiya city, Nov. 1998. [email protected]

External and Internal Incompressible Viscous Flows Computation using Taylor Series Expansion and Least Square based Lattice Boltzmann Method

The lattice Boltzmann method (LBM) has recently become an alternative and promising computational fluid dynamics approach for simulating complex fluid flows. Despite its enormous success in many practical applications, the standard LBM is restricted to the lattice uniformity in the physical space. This is the main drawback of the standard LBM for flow problems with complex geometry. Several app...

سیستمهای الکترونی همبسته قوی در شبکه‌های ناکام

 We give an overview of recent work on charge degrees of freedom of strongly correlated electrons on geometrically frustrated lattices. Special attention is paid to the checkerboard lattice, i.e., the two-dimensional version of a pyrochlore lattice and to the kagomé lattice. For the checkerboard lattice it is shown that at half filling when spin degrees of freedom are neglected and at quarter f...

Gauge Coupling Unification from Unified Theories in Higher Dimensions

A two-stage framework for unification is proposed involving grand unification, supersymmetry and extra dimensions, leading to a prediction for the strong gauge coupling, αKK s = 0.118±0.004±0.003, which is more successful and precise than that obtained from conventional supersymmetric grand unification, αSGUT s = 0.130 ± 0.004 ± ∆SGUT. Orbifold breaking of the unified gauge group leads to a non...
