Projective Time, Cayley Transformations and the Schwarzian Geometry of the Free Particle--Oscillator Correspondence
Andrey Alcala, Mikhail S. Plyushchay
We investigate the relation between the one--dimensional free particle and the harmonic oscillator from a unified viewpoint based on projective geometry, Cayley transformations, an…
The soliton nature of the super-Klein tunneling effect
Francisco Correa, Luis Inzunza, Olaf Lechtenfeld
We establish a relationship between the Davey--Stewartson II (DS II) integrable system in dimensions and quasi-exactly solvable planar interacting Dirac Hamiltonians that…
Confining kinks. -regularized one-loop kink mass shifts in exotic field theories
Luis Inzunza, Juan Mateos Guilarte, Pablo Pais
By combining stability analysis of scalar field theories with the Darboux transformation technique, we create models featuring kink-like solutions whose quantum perturbations are a…
Coupling and particle number intertwiners in the Calogero model
Francisco Correa, Luis Inzunza, Olaf Lechtenfeld
It is long known that quantum Calogero models feature intertwining operators, which increase or decrease the coupling constant by an integer amount, for any fixed number of particl…
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…
A Casimir operator for a Calogero algebra
Francisco Correa, Gonzalo Leal, Olaf Lechtenfeld +1
We investigate the nonlinear algebra generated by the 9 functionally independent permutation-symmetric operators in the three-particle rational quantum Calogero model. Decoup…
Weak-strong duality of the non-commutative Landau problem induced by a two-vortex permutation, and conformal bridge transformation
Andrey Alcala, Mikhail S. Plyushchay
A correspondence is established between the dynamics of the two-vortex system and the non-commutative Landau problem (NCLP) in its sub- (non-chiral), super- (chiral) and critical p…
Gravity coupled to a scalar field from a Chern-Simons action: describing rotating hairy black holes and solitons with gauge fields
Marcela Cárdenas, Oscar Fuentealba, Cristián Martínez +1
Einstein gravity minimally coupled to a scalar field with a two-parameter Higgs-like self-interaction in three spacetime dimensions is recast in terms of a Chern-Simons form for th…
Thermal fluctuations of black holes with non-linear electrodynamics and charged Renyi entropy
Gabriel Arenas-Henriquez, Felipe Diaz, Yerko Novoa
We extend the charged Renyi entropy to a more general holographic scenario. Coupling an arbitrary non-linear electrodynamics Lagrangian density to AdS gravity, we analyse the therm…
Vortex solutions in the presence of Dark Portals
Paola Arias, Ariel Arza, Fidel A. Schaposnik +2
The existence of hidden sectors weakly coupled to the visible one has been extensively studied as a way to extend the Standard Model (SM) and to provide a good dark matter candidat…
Conformal bridge transformation, - and super- symmetry
Luis Inzunza, Mikhail S. Plyushchay
Supersymmetric extensions of the 1D and 2D Swanson models are investigated by applying the conformal bridge transformation (CBT) to the first order Berry-Keating Hamiltonian multip…
Phase transitions of black strings in dynamical Chern-Simons modified gravity
Cristóbal Corral, Cristián Erices, Daniel Flores-Alfonso +1
We study conserved charges and thermodynamics of analytic rotating anti-de Sitter black holes with extended horizon topology -- also known as black strings -- in dynamical Chern-Si…
The First Law for the Lorentzian Rotating Taub-NUT
Ernesto Frodden, Diego Hidalgo
We show that the first law for the rotating Taub-NUT is straightforwardly established with the surface charge method. The entropy is explicitly found as a charge, and its value is…
Dynamics, symmetries, anomaly and vortices in a rotating cosmic string background
Luis Inzunza, Mikhail S. Plyushchay
Non-relativistic conformally invariant systems in a rotating cosmic string (conical) spacetime are analyzed at the classical and quantum levels by means of the gravitoelectromagnet…
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…
Kinetic and Magnetic Mixing with Antisymmetric Gauge Fields
J. Gamboa, J. Lopez-Sarrion, F. Mendez
A general procedure to describe the coupling between antisymmetric gauge fields is proposed. For vector gauge theories the inclusion of magnetic mixing in…
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…
Conformal bridge transformation and PT symmetry
Luis Inzunza, Mikhail S. Plyushchay
The conformal bridge transformation (CBT) is reviewed in the light of the symmetry. Originally, the CBT was presented as a non-unitary transformation (a complex cano…
Conformal bridge in a cosmic string background
Luis Inzunza, Mikhail S. Plyushchay
Hidden symmetries of non-relativistic invariant systems in a cosmic string background are studied using the conformal bridg…
Solitons and instantons in vacuum stability: physical phenomena
J. A. Gonzalez, A Bellorin, L E Guerrero +3
In a previous paper [JCAP06, 033 (2018)] we have proved that it is possible to have a stable false vacuum in a potential that is unbounded from below. In this paper we discuss the…
Non-Perturbative Aspects of Spontaneous Symmetry Breaking
Jorge Gamboa, Justo Lopez-Sarrion
Spontaneous symmetry breaking is studied in the ultralocal limit of a scalar quantum field theory, that is when (or infrared limit). In this limit we show that a $ φ^4…
Deformed Quantum Mechanics and the Landau Problem
J. Gamboa, F. Méndez
A deformation of the Landau problem based on a modification of Fock algebra is considered. Systems with Hamiltonians f(H) where H is the Landau Hamiltonian in the lowest level are…
Deformed classical-quantum mechanics transition
Jose L. Cortes, J. Gamboa
An approach to study a generalization of the classical-quantum transition for general systems is proposed. In order to develop the idea, a deformation of the ladder operators algeb…
Hidden symmetry and (super)conformal mechanics in a monopole background
Luis Inzunza, Mikhail S. Plyushchay, Andreas Wipf
We study classical and quantum hidden symmetries of a particle with electric charge in the background of a Dirac monopole of magnetic charge subjected to an additional cent…
