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…
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…
A Lie-Jordan Geometric Formulation of Lindblad Dynamics
Leonel Bixano, Victor Alberto Cruz-Barriguete, Guillermo López-Alvarez +3
We develop a Lie-Jordan geometric formulation of finite-dimensional open quantum dynamics, building on the algebraic framework introduced in our previous work (arXiv:2606.26477). T…
Algebraic structures of the Lindblad equation
Leonel Bixano, Guillermo López-Alvarez, Victor Alberto Cruz-Barriguete +4
We investigate the algebraic structure underlying the Lindblad equation for finite-dimensional open quantum systems. By introducing a suitable operator representation of the Liouvi…
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…
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 $\…
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…
Generalized Ernst Potentials for arbitrary Dilatonic Theories
Leonel Bixano, Tonatiuh Matos
In this work, we generalize Ernst potentials to the Einstein-Maxwell-Dilaton case and explicitly write the corresponding potential space metric. Since this metric is five-dimension…
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…
The space-time structure of an untouchable naked singularity in superstrings theory
Leonel Bixano, Tonatiuh Matos
According to the Cosmic Censorship Conjecture, naked singularities are believed to be forbidden in nature and must remain hidden by an event horizon. In this work, we present the c…
On the Possibility of the Existence of Wormholes in Nature
Leonel Bixano, Tonatiuh Matos
To date, many exotic predictions of Einstein's equations have been corroborated, with one exception: wormholes (WHs). In this work, we analyse a new exact solution combination to t…
Einstein-Maxwell-Dilaton Wormholes that meet the Energy Conditions
Leonel Bixano, Tonatiuh Matos
One of the latest predictions of Einstein's theory is the existence of Wormholes (WH). In this work, we present exact solutions of the Einstein-Maxwell-Dilaton equations representi…
