Enhanced asymptotic BMS3 algebra of the flat spacetime solutions of generalized minimal massive gravity

open access: yesNuclear Physics B, 2018
We apply the new fall of conditions presented in the paper [1] on asymptotically flat spacetime solutions of Chern–Simons-like theories of gravity. We show that the considered fall of conditions asymptotically solve equations of motion of generalized ...

On correlation functions in models related to the Temperley-Lieb algebra

open access: yesSciPost Physics
We deal with quantum spin chains whose Hamiltonian arises from a representation of the Temperley-Lieb algebra, and we consider the mean values of those local operators which are generated by the Temperley-Lieb algebra.

Three-dimensional dynamics of four-dimensional topological BF theory with boundary

open access: yesNew Journal of Physics, 2012
We consider the four-dimensional (4D) abelian topological BF theory with a planar boundary, following Symanzik's method. We find the most general boundary conditions compatible with the field equations broken by the boundary.

Quadrature Current Compensation in Non-Sinusoidal Circuits Using Geometric Algebra and Evolutionary Algorithms

open access: yesEnergies, 2019
Non-linear loads in circuits cause the appearance of harmonic disturbances both in voltage and current. In order to minimize the effects of these disturbances and, therefore, to control the flow of electricity between the source and the load, passive or ...

A supersymmetric extension of w 1+∞ algebra in the celestial holography

open access: yesJournal of High Energy Physics
We determine the N $$ \mathcal{N} $$ = 1 supersymmetric topological W ∞ algebra by using the λ deformed bosons (β, γ) and fermions (b, c) ghost system. By considering the real bosons and the real fermions at λ = 0 (or λ = 1 2 $$ \frac{1}{2} $$ ), the N $$

Brauer algebras of type B

open access: yes, 2011
For each n>0, we define an algebra having many properties that one might expect to hold for a Brauer algebra of type Bn. It is defined by means of a presentation by generators and relations. We show that this algebra is a subalgebra of the Brauer algebra
