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…

A black hole solution in conformal supergravity

Pedro D. Alvarez, Cristóbal Corral, Jorge Zanelli

We present a three-parameter family of analytic black-hole solutions in the bosonic sector of a four-dimensional supersymmetric model with matter fields in the adjoint representati…

Embedding of the Georgi-Glashow $S U (5)$ model in the superconformal algebra

Pedro D. Alvarez, Rafael A. Chavez, Jorge Zanelli

We present a scheme to construct grand unified models based on the superconformal algebra and the inclusion of matter fields in the adjoint representation of supersymmetry. As an i…

Pseudoclassical system with gauge and time-reparametrization invariance

Mauricio Valenzuela

We present a pseudoclassical mechanics model which exhibits gauge symmetry and time-reparametrization invariance. As such, first- and second-class constraints restrict the phase sp…

QED Fermions in a noisy magnetic field background

Jorge David Castaño-Yepes, Marcelo Loewe, Enrique Muñoz +2

We consider the effects of a noisy magnetic field background over the fermion propagator in QED, as an approximation to the spatial inhomogeneities that would naturally arise in ce…

Electric/Magnetic Newton-Hooke and Carroll Jackiw-Teitelboim Gravity

Luis Avilés, Joaquim Gomis, Diego Hidalgo +1

We construct the electric and magnetic Newton-Hooke and Carroll Jackiw-Teitelboim gravity theories using the isomorphism of Newton-Hooke $_{\pm}$ and (A-)dS Carroll algebras in $(1+1)…

MOA-2020-BLG-208Lb: Cool Sub-Saturn Planet Within Predicted Desert

Greg Olmschenk, David P. Bennett, Ian A. Bond +74

We analyze the MOA-2020-BLG-208 gravitational microlensing event and present the discovery and characterization of a new planet, MOA-2020-BLG-208Lb, with an estimated sub-Saturn ma…

Nonlinear automorphism of the conformal algebra in 2D and continuous $T T ˉ$ deformations

David Tempo, Ricardo Troncoso

The conformal algebra in 2D (Diff( $S^{1}$ ) $\oplus$ Diff( $S^{1}$ )) is shown to be preserved under a nonlinear map that mixes both chiral (holomorphic) generators $T$ and $T ˉ$ . I…

The Casimir effect in chiral media using path integral techniques

Fabrizio Canfora, David Dudal, Thomas Oosthuyse +2

We employ path integral methods to calculate the Casimir energy and force densities in a chiral extension of QED. Manifestly gauge invariant perfect electromagnetic boundary condit…

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…

On the robustness of solitons crystals in the Skyrme model

Gonzalo Barriga, Fabrizio Canfora, Marcela Lagos +2

In this work we analize how the inclusion of extra mesonic degrees of freedom affect the finite density solitons crystals of the Skyrme model. In particular, the first analytic exa…

A search for transit timing variations in the HATS-18 planetary system

John Southworth, A. J. Barker, T. C. Hinse +23

HATS-18b is a transiting planet with a large mass and a short orbital period, and is one of the best candidates for the detection of orbital decay induced by tidal effects. We pres…

On the spin content of the classical massless Rarita--Schwinger system

Mauricio Valenzuela, Jorge Zanelli

We analyze the Rarita--Schwinger (RS) massless theory in the Lagrangian and Hamiltonian approaches. At the Lagrangian level, the standard gamma-trace gauge fixing constraint leaves…

Physical properties of near-Earth asteroid (2102) Tantalus from multi-wavelength observations

Agata Rożek, Stephen C. Lowry, Benjamin Rozitis +20

Between 2010 and 2017 we have collected new optical and radar observations of the potentially hazardous asteroid (2102)~Tantalus from the ESO NTT and Danish telescopes at the La Si…

Analytic meronic black holes, gravitating solitons and higher spins in the Einstein $S U (N)$ -Yang-Mills theory

Fabrizio Canfora, Andrés Gomberoff, Marcela Lagos +1

We construct meronic black holes and solitons in the Einstein $S U (N)$ -Yang-Mills theory in $D = 4$ and $D = 5$ dimensions. These analytical solutions are found by combining the general…
