  • Maximum Entropy Conjecture for Black Hole Mergers

    Author(s): Monica Rincon-Ramirez, Nathan K. Johnson-McDaniel, Eugenio Bianchi, Ish Gupta, Vaishak Prasad, and B. S. Sathyaprakash The remnant properties of black hole mergers may be governed by a maximum entropy bound suggesting that once the black holes become sufficiently close together, the throat around both black holes resembles that of an individual Kerr black hole to a far-away observer, and thus the Kerr entropy computation becomes valid...

  • Evidence for Three Subpopulations of Merging Binary Black Holes at Different Primary Masses

    Author(s): Sharan Banagiri, Eric Thrane, and Paul D. Lasky Different analyses of gravitational-wave observations are converging on evidence for a distinct population of massive black hole binaries produced through repeated mergers. [Phys. Rev. Lett. 137, 021403] Published Mon Jul 06, 2026

  • Origin of Misleading Convergence in Self-Consistent Many-Electron Theories: Fundamental Aspects and Practical Implications

    Author(s): Herbert Eßl, Matthias Reitner, Evgeny Kozik, and Alessandro Toschi Formally disentangling the issue of misleading convergence observed in iterative many-body schemes from the branching of the Luttinger-Ward functional provides a rigorous, model-independent procedure converging to a physical solution.

  • Ab Initio Free-Energy Surfaces for Coupled Ion-Electron Transfer

    Author(s): Ethan Abraham, Martin Z. Bazant, and Troy Van Voorhis A physically consistent formalism provides a first-principles route to electrochemical current-overpotential relations by computing finite-temperature coupled ion-electron transfer free-energy surfaces from constrained ab initio trajectories.
