Special Issue Information

Dear Colleagues,

Black holes, as the most extreme and enigmatic objects in the universe, provide profound insights into the fundamental laws of physics. Their event horizons, singularities, and thermodynamic properties reveal surprising connections between gravity, quantum mechanics, and statistical mechanics. The holographic principle has improved our understanding of black holes, offering a dual perspective through lower-dimensional quantum field theories and uncovering the chaotic nature of black holes. Quantum chaos focuses on how dynamical systems exhibit extreme sensitivity to initial conditions within the framework of quantum theory. Many quantum systems, particularly those related to black holes, demonstrate chaotic behaviors marked by thermalization, entanglement dynamics, scrambling, and spectral statistics. Quantum chaos bridges the complex dynamics of strongly correlated systems with the semiclassical dynamics near black hole horizons and the contributions of wormhole geometries. Symmetry is crucial for understanding the structure and dynamics of chaotic quantum systems and black holes. For instance, discrete symmetries determine the universality classes of spectral statistics in chaotic systems, while continuous symmetries govern conserved quantities that constrain chaotic dynamics and serve as parameters for black hole solutions. This Special Issue aims to investigate the complex relationships between black holes, symmetry, and chaos, with a focus on recent breakthroughs and emerging directions in this interdisciplinary field.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We developed a self-consistent double-null description of an evaporating white-hole spacetime by embedding the outgoing Vaidya solution in a coordinate system that remains regular across the future horizon. Starting from the radiation-coordinate form, we specialize in retarded time so that a monotonically decreasing mass function M(u) encodes outgoing positive-energy flux. Expressing the metric in null coordinates (u,v), Einstein’s equations for a single-directional null-dust stress–energy tensor, Tuu=ρ(u), then reduce to one first-order PDE for the areal radius: ∂vr=B(u)1−2M(u)/r. Its integral, r+2M(u)ln|r−2M(u)|=v−C(u), defines an implicit foliation of outgoing null cones. The metric coefficient follows algebraically as f(u,v)=1−2M(u)/r. Residual gauge freedom in B(u) and C(u) is fixed so that u matches the Bondi retarded time at null infinity, while v remains analytic at the apparent horizon, generalizing the Kruskal prescription to dynamical mass loss. In the limit M(u)→M, the construction reduces to the familiar Eddington–Finkelstein and Kruskal forms. Our solution, therefore, provides a compact analytic framework for studying white-hole evaporation, Hawking-like energy fluxes, and back-reaction in spherically symmetric settings without encountering coordinate singularities.
