u-Deformed WZW Model and Its Gauging [PDF]

, 2006
We review the description of a particular deformation of the WZW model. The resulting theory exhibits a Poisson-Lie symmetry with a non-Abelian cosymmetry group and can be vectorially gauged.Comment: This is a contribution to the Proc.

The Co-Points of Rays are Cut Points of Upper Level Sets for Busemann Functions [PDF]

, 2016
. We show that the co-rays to a ray in a complete non-compact Finsler manifold contain geodesic segments to upper level sets of Busemann functions. Moreover, we characterise the co-point set to a ray as the cut locus of such level sets.

Casimir repulsion between metallic objects in vacuum

, 2010
We give an example of a geometry in which two metallic objects in vacuum experience a repulsive Casimir force. The geometry consists of an elongated metal particle centered above a metal plate with a hole.

Electroweak Interaction Model with an Undegenerate Double Symmetry [PDF]

, 2005
The initial $P$-invariance of the electroweak interaction Lagrangian together with the low-energy results of the Weinberg-Salam model is provided by a local secondary symmetry.

Quantum gravity from Weyl conformal geometry

European Physical Journal C: Particles and Fields
We review recent developments in physical implications of Weyl conformal geometry. The associated Weyl quadratic gravity action is a gauge theory of the Weyl group of dilatations and Poincaré symmetry.

On the coupling of Galilean-invariant field theories to curved spacetime

SciPost Physics, 2018
We consider the problem of coupling Galilean-invariant quantum field theories to a fixed spacetime. We propose that to do so, one couples to Newton-Cartan geometry and in addition imposes a one-form shift symmetry.

Pseudo-Riemannian structures in Pati-Salam models

Journal of High Energy Physics, 2020
We discuss the role of the pseudo-Riemannian structure of the finite spectral triple for the family of Pati-Salam models. We argue that its existence is a very restrictive condition that separates leptons from quarks, and restricts the whole family of ...

Generalized teleparallel de Sitter geometries

European Physical Journal C: Particles and Fields, 2023
Theories of gravity based on teleparallel geometries are characterized by the torsion, which is a function of the coframe, derivatives of the coframe, and a zero curvature and metric compatible spin-connection.

Zamolodchikov Tetrahedral Equation and Higher Hamiltonians of 2d Quantum Integrable Systems [PDF]

, 2017
. The main aim of this work is to develop a method of constructing higher Hamiltonians of quantum integrable systems associated with the solution of the Zamolodchikov tetrahedral equation. As opposed to the result of V.V. Bazhanov and S.M.
