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…
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 have attracted considerable attention. 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…
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…
