Nonaxisymmetric (2+1) black holes with Dym boundary conditions
Miguel Pino, Francisco Reyes
We present the spectrum of stationary black hole solutions associated with the first nontrivial member of the Dym family of boundary conditions. The analysis combines the holonomy…
Integrable black hole dynamics in the asymptotic structure of AdS
Marcela Cárdenas, Francisco Correa, Miguel Pino
This work deepens the study of integrable asymptotic symmetries for AdS. They are given by an infinite set of integrable nonlinear equations known as the Ablowitz-Kaup-Newell…
1/c deformations of AdS boundary conditions and the Dym hierarchy
Kristiansen Lara, Miguel Pino, Francisco Reyes
This work introduces a novel family of boundary conditions for AdS General Relativity, constructed through a polynomial expansion in negative integer powers of the Brown-Hennea…
Teaching physics in real-life contexts: The Beirut explosion
Mauricio Echiburu, Carla Hernández, Miguel Pino
Teaching physics in real-life contexts continues to be a challenge for teachers at different educational levels. In this article, three Context-Rich Problems are proposed to be imp…
DC conductance and memory in 3D gravity
Márcela Cárdenas, Hernán A. González, Kristiansen Lara +1
Transport properties are investigated in the two-dimensional dual dynamics of AdS gravity. By providing boundary conditions that deform the ADM lapse and shift functions, we…
Integrable Systems and Spacetime Dynamics
Marcela Cárdenas, Francisco Correa, Kristiansen Lara +1
It is shown that the Ablowitz-Kaup-Newell-Segur (AKNS) integrable hierarchy can be obtained as the dynamical equations of three-dimensional General Relativity with a negative cosmo…
The anisotropic chiral boson
Oscar Fuentealba, Hernán A. González, Miguel Pino +1
We construct the theory of a chiral boson with anisotropic scaling, characterized by a dynamical exponent , whose action reduces to that of Floreanini and Jackiw in the isotropi…
Revisiting the asymptotic dynamics of General Relativity on AdS
Hernán A. González, Javier Matulich, Miguel Pino +1
The dual dynamics of Einstein gravity on AdS supplemented with boundary conditions of KdV-type is identified. It corresponds to a two-dimensional field theory at the boundary,…
Integrable systems with BMS Poisson structure and the dynamics of locally flat spacetimes
Oscar Fuentealba, Javier Matulich, Alfredo Pérez +4
We construct a hierarchy of integrable systems whose Poisson structure corresponds to the BMS algebra, and then discuss its description in terms of the Riemannian geometry of…
Extended Symmetries at the Black Hole Horizon
Laura Donnay, Gaston Giribet, Hernán A. González +1
We prove that non-extremal black holes in four-dimensional general relativity exhibit an infinite-dimensional symmetry in their near horizon region. By prescribing a physically sen…
Supertranslations and Superrotations at the Black Hole Horizon
Laura Donnay, Gaston Giribet, Hernan A. Gonzalez +1
We show that the asymptotic symmetries close to nonextremal black hole horizons are generated by an extension of supertranslations. This group is generated by a semidirect sum of V…
Dark energy and Equivalence Principle constraints from astrophysical tests of the stability of the fine-structure constant
C. J. A. P. Martins, A. M. M. Pinho, R. F. C. Alves +3
Astrophysical tests of the stability of fundamental couplings, such as the fine-structure constant , are becoming an increasingly powerful probe of new physics. Here we discuss…
Cosmological Kinetic Mixing
Ashok Das, Jorge Gamboa, Miguel Pino
In this paper we generalize the kinetic mixing idea to time reparametrization invariant theories, namely, relativistic point particles and cosmology in order to obtain new insights…
Higgs Model Coupled to Dark Photons
Dante Cárcamo, Jorge Gamboa, Miguel Pino
A dark sector containing a Higgs field and a dark photon coupled to visible photons via a small kinetic mixing is considered. The mass of the dark gauge boson becomes rescaled by t…
Boundary dynamics of asymptotically flat 3D gravity coupled to higher spin fields
Hernan A. Gonzalez, Miguel Pino
We construct a two-dimensional action principle invariant under a spin-three extension of BMS group. Such a theory is obtained through a reduction of Chern-Simons action with a…
The Boulware-Deser mode in Zwei-Dreibein gravity
Máximo Bañados, Cedric Deffayet, Miguel Pino
Massive gravity in three dimensions accepts several different formulations. Recently, the 3-dimensional bigravity dRGT model in first order form, Zwei-Dreibein gravity, was conside…
Asymptotically flat spacetimes in three-dimensional higher spin gravity
Hernan A. Gonzalez, Javier Matulich, Miguel Pino +1
A consistent set of asymptotic conditions for higher spin gravity in three dimensions is proposed in the case of vanishing cosmological constant. The asymptotic symmetries are foun…
Asymptotically flat spacetimes in 3D bigravity
Hernan A. Gonzalez, Miguel Pino
We report that a class of three-dimensional bimetric theories contain asymptotically flat solutions. These spacetimes can be cast in a set of asymptotic conditions at null infinity…
A note on the Cardy formula and black holes in 3d (massive) bigravity
Máximo Bañados, Miguel Pino
We report full agreement between the Bekenstein-Hawking semiclassical entropy and Cardy's formula for black holes in 3d (massive) bigravity. Since this theory does have local bulk…
The bigravity black hole and its thermodynamics
Máximo Bañados, Andrés Gomberoff, Miguel Pino
We argue that the Isham-Storey exact solution to bigravity does not describe black holes because the horizon is a singular surface. However, this is not a generic property of bigra…
