Article Citation - WoS: 1Citation - Scopus: 1AdS3 Black Holes with Primary Proca Hair from a Regularized Gauss-Bonnet Coupling(Amer Physical Soc, 2025) Alkac, Gokhan; Mesta, Murat; Unal, GonulWe construct a consistent three-dimensional Einstein-Gauss-Bonnet theory as a vector-tensor theory within the generalized Proca class by employing a regularization procedure based on the Weyl geometry, which was introduced recently by Charmousis, Fernandes, and Hassaine [Phys. Rev. D 111, 124008 (2025).]. We then obtain an asymptotically Anti-de Sitter (AdS3), static, and circularly symmetric black hole solution with primary Proca hair. Afterward, we investigate the effect of the scalar-tensor GaussBonnet coupling constructed previously by different regularization schemes. We further generalize these solutions by incorporating an electric charge. As special cases, we find a regular black hole solution in addition to charged and uncharged stealth Banados-Teitelboim-Zanelli black hole solutions.Article Citation - WoS: 1Citation - Scopus: 1Simulating Hawking Radiation in Quantum Many-Body Systems: Deviations From the Thermal Spectrum(Elsevier, 2025) Alkac, Gokhan; Ozgun, EgeWe investigate a recently proposed one-to-one correspondence between quantum field theories in twodimensional curved spacetime and quantum many-body systems, which enables the simulation of Hawking radiation in static background spacetimes. In particular, we demonstrate that deviations from the thermal spectrum, as predicted by the well-known tunneling method, can be observed in many-body simulations.
