Two-particle irreducible effective action in Gauge theories
(Springer/Plenum Publishers, 2004-12)
The goal of this paper is to develop the formalism of the two-particle irreducible (2PI) (G. Baym (1962). Physical Review 127, 1391; H. D. Dahmen and G. Jona Lasino (1962). Nuovo Cimento A 52, 807; C. de Dominicis and P. ...
Vortices in fracton type gauge theories
(Elsevier Science, 2020-12)
We consider a vector gauge theory in 2+1 dimensions of the type recently proposed by Radzihovsky and Hermele [1] to describe fracton phases of matter. The theory has U(1)×U(1) vector gauge fields coupled to an additional ...
Deformed Weitzenböck Connections and Double Field Theory
(Wiley VCH Verlag, 2019-03)
We revisit the generalized connection of Double Field Theory. We implement a procedure that allow us to re-write the Double Field Theory equations of motion in terms of geometric quantities (like generalized torsion and ...
Gauge symmetry enhancing-breaking from a Double Field Theory perspective
(Springer, 2017-07)
Gauge symmetry enhancing, at specific points of the compactification space, is a distinguished feature of string theory. In this work we discuss the breaking of such symmetries with tools provided by Double Field Theory ...
L ∞ algebras and tensor hierarchies in Exceptional Field Theory and Gauged Supergravity
(Springer, 2019-01)
We show how the gauge and field structure of the tensor hierarchies in Double and E7(7) Exceptional Field Theory fits into L∞ algebras. Special attention is paid to redefinitions, the role of covariantly constrained fields ...
Helmholtz Theorems, Gauge Transformations, General Covariance and the Empirical Meaning of Gauge Conditions
(Scientific Research Publishing, 2016-05)
It is well known that the use of Helmholtz decomposition theorem for static vector fields C : R3 → R3 ,
when applied to the time dependent vector fields E : R4 → R3 , B : R4 → R3 which represent the
electromagnetic field, ...
Symmetry enhancement interpolation, non-commutativity and Double Field Theory
(Springer, 2019-03)
We present a moduli dependent target space effective field theory action for (truncated) heterotic string toroidal compactifications. When moving continuously along moduli space, the stringy gauge symmetry enhancement-breaking ...
Nonsupersymmetric gauge coupling unfication in [SU(6)]4× Z4 and proton stability
(Sociedad Mexicana de Física A.C.Grupo de Fenomenología de Interacciones FundamentalesCiudad de México, México, 2022)
Gauge invariant fluctuations of the metric during inflation from a new scalar-tensor Weyl-integrable gravity model
(American Physical Society, 2016-09)
We investigate gauge invariant scalar fluctuations of the metric during inflation in a nonperturbative formalism in the framework of a recently formulated scalar-tensor theory of gravity, in which the geometry of space-time ...
