Harmonic branches of Einstein--Maxwell--scalar field gravity: exact solutions and regularity
Leonel Bixano, Tonatiuh Matos
We relate black-hole horizons and wormhole throats to the geometry of the harmonic branches of Einstein--Maxwell--dilaton gravity. In the unified Ernst framework, we first solve th…
Canonical Quantization and Constraint Algebra of Weyl-Invariant Gravity in a Conformal Gauge: Emergence of a Geometric Cosmological Term
Jorge Meza-Domínguez, Tonatiuh Matos
We present the canonical quantization of Weyl-invariant gravity in a specific conformal gauge. Fixing the scale factor as yields an effective geometric cosmologic…
Potential-space geometry and scalar rigidity of the Plebański-Demiański ansatz without a cosmological constant
Leonel Bixano, Tonatiuh Matos
We analyze stationary, axisymmetric Einstein-Maxwell-dilaton theory with zero cosmological constant in the conformal Carter class, employing a generalized Ernst approach on the spa…
Determination of the metric of a Schwarzschild black hole surrounded by a halo of dark matter
M. Castillo Alarcón, Leonel Bixano, I. A. Sarmiento-Alvarado +2
Following the landmark acquisition of the first image of a black hole, systems comprising a black hole enveloped by a dark matter halo have attracted considerable attention. This w…
A Covariant Chiral-Hydrodynamic Formulation of the Dirac Equation in Curved Spacetime
Jorge Meza-Domínguez, Tonatiuh Matos
The hydrodynamic formulation of the Dirac equation has historically been hindered by the inability to close the system of physical variables without resorting to infinite moment hi…
Potential Space Symmetries in Ernst-like Formulations of Einstein-Maxwell/ModMax-Scalar field Theories
Leonel Bixano, Tonatiuh Matos
We complete the visible, hidden, sectorial, and discrete symmetries of Ernst-like potential spaces in stationary, axisymmetric Einstein-Maxwell-Scalar Field (EMSF) and Einstein-Mod…
Exact rotating dilatonic branch in ModMax electrodynamics without Maxwell analogue
Leonel Bixano, Tonatiuh Matos
We present a novel class of rotating dilatonic solutions within the framework of Einstein-ModMax-type gravity. The configuration belongs to the nonlinear sector characterized by $\…
Canonical Uncertainty Relations for Madelung Variables in Curved Spacetime: Relating Dark Matter Cores and Unruh Radiation
Jorge Meza-Domínguez, Tonatiuh Matos
We establish fundamental uncertainty relations for the hydrodynamic variables arising from the Madelung representation of quantum fields in curved spacetime. Through canonical quan…
Generalized Einstein-ModMax-ScalarField theories and new exact solutions
Leonel Bixano, Tonatiuh Matos
We present a generalized Ernst-type framework for stationary, axisymmetric spacetimes in which a scalar field is coupled to the electrodynamic field, with a particular focus on the…
One-dimensional subspaces of the Chiral Equations
I. A. Sarmiento-Alvarado, Petra Wiederhold, Tonatiuh Matos
In this work we find solutions of the ()-dimensional Einstein Field Equations (EFE) with commuting Killing vectors in vacuum. In the presence of Killing vectors, the E…
Axially symmetric wormholes
I. A. Sarmiento-Alvarado, Leonel Bixano, Tonatiuh Matos
In this work, we derive an exact vacuum solution to the Einstein field equations that depends on three constant parameters: the throat radius , a parameter , which is close…
A Brief Review of Wormhole Cosmic Censorship
Leonel Bixano, I. A. Sarmiento-Alvarado, Tonatiuh Matos
Spacetime singularities, in the sense that curvature invariants are infinite at some point or region, are thought to be impossible to observe, and must be hidden within an event ho…
Wormholes exact solutions in high dimensions General Relativity
I. A. Sarmiento-Alvarado, Leonel Bixano, Tonatiuh Matos
In the present work, we develop and examine a series of exact solutions to Einstein's 5-dimensional field equations in the vacuum, which depend on two constant parameters, and…
Cosmic Acceleration from topological considerations III: Lie group
I. A. Sarmiento Alvarado, Maribel Hernández Márquez, Tonatiuh Matos
Recent observations on the large-scale structure of the universe indicate that the cosmological constant cannot be the definitive answer to the nature of dark energy. Therefore, it…
