Magnetic Carrollian gravity from the Carroll algebra
Andrea Campoleoni, Marc Henneaux, Simon Pekar +2
We explicitly establish the equivalence between the magnetic Carrollian limit of Einstein gravity defined through the Hamiltonian formalism and the Carrollian theory of gravity def…
Asymptotic symmetries and soft charges of fractons
Alfredo Pérez, Stefan Prohazka
The asymptotic structure of gauge theories describing fracton interactions is analyzed. Two sets of asymptotic conditions are proposed. Both encompass all known solutions, lead to…
Asymptotic symmetries in Carrollian theories of gravity with a negative cosmological constant
Alfredo Pérez
Asymptotic symmetries of electric and magnetic Carrollian gravitational theories with a negative cosmological constant are analyzed in 3+1 space-time dimensions. In the magneti…
Efficient Asymmetric photothermal source: Designing a heating Janus-Nanojet
Javier González-Colsa, Alfredo Franco Pérez, Fernando Bresme +2
Janus particles have flourished as subject of intensive research due to their synergetic properties and their promising use in different fields, especially in biomedicine. The comb…
Asymptotic symmetries in Carrollian theories of gravity
Alfredo Pérez
Asymptotic symmetries in Carrollian gravitational theories in 3+1 space and time dimensions obtained from "magnetic" and "electric" ultrarelativistic contractions of General Relati…
Integrable systems and the boundary dynamics of (higher spin) gravity on AdS
Emilio Ojeda
This thesis extends a previously found relation between the integrable KdV hierarchy and the boundary dynamics of pure gravity on AdS described in the highest weight gauge, to…
Integrable systems and the boundary dynamics of higher spin gravity on AdS
Emilio Ojeda, Alfredo Pérez
We introduce a new set of boundary conditions for three-dimensional higher spin gravity with gauge group , where its dynamics at the bounda…
Gravitational dual of averaged free CFT's over the Narain lattice
Alfredo Pérez, Ricardo Troncoso
It has been recently argued that the averaging of free CFT's over the Narain lattice can be holographically described through a Chern-Simons theory for $U\left(1\right)^{D}\times U…
Spacetime structure near generic horizons and soft hair
Daniel Grumiller, Alfredo Pérez, M. M. Sheikh-Jabbari +2
We explore the spacetime structure near non-extremal horizons in any spacetime dimension greater than two and discover a wealth of novel results: 1. Different boundary conditions a…
Boundary conditions for General Relativity in three-dimensional spacetimes, integrable systems and the KdV/mKdV hierarchies
Emilio Ojeda, Alfredo Pérez
We present a new set of boundary conditions for General Relativity on AdS, where the dynamics of the boundary degrees of freedom are described by two independent left and right…
Bondi-Metzner-Sachs invariance and electric-magnetic duality
Claudio Bunster, Andrés Gomberoff, Alfredo Pérez
We exhibit a Hamiltonian formulation, both for electromagnetism and gravitation, in which it is not required that the Bondi "news" vanish, but only that the incoming news be equal…
Regge-Teitelboim analysis of the symmetries of electromagnetic and gravitational fields on asymptotically null spacelike surfaces
Claudio Bunster, Andrés Gomberoff, Alfredo Pérez
We present a new application of the Regge-Teitelboim method for treating symmetries which are defined asymptotically. It may be regarded as complementary to the one in their origin…
Extended anti-de Sitter Hypergravity in Dimensions and Hypersymmetry Bounds
Marc Henneaux, Alfredo Pérez, David Tempo +1
In a recent paper (JHEP {\bf 1508} (2015) 021), we have investigated hypersymmetry bounds in the context of simple anti-de Sitter hypergravity in dimensions. We showed that t…
Lie Group S-Expansions and Infinite-dimensional Lie algebras
Hernán Astudillo, Ricardo Caroca, Alfredo Pérez +1
The expansion method of Lie algebras by a semigroup or S-expansion is generalized to act directly on the group manifold, and not only at the level of its Lie algebra. The consisten…
Generating Higher-Order Lie Algebras by Expanding Maurer Cartan Forms
Ricardo Caroca, Nelson Merino, Alfredo Pérez +1
By means of a generalization of the Maurer-Cartan expansion method we construct a procedure to obtain expanded higher-order Lie algebras. The expanded higher order Maurer-Cartan eq…
Standard General Relativity from Chern-Simons Gravity
Fernando Izaurieta, Paul Minning, Alfredo Pérez +2
Chern-Simons models for gravity are interesting because they provide with a truly gauge-invariant action principle in the fiber-bundle sense. So far, their main drawback has largel…
Dual Formulation of the Lie Algebra S-expansion Procedure
Fernando Izaurieta, Alfredo Pérez, Eduardo Rodríguez +1
The expansion of a Lie algebra entails finding a new, bigger algebra G, through a series of well-defined steps, from an original Lie algebra g. One incarnation of the method, the s…
