The crucial argument resides in their common aim of generalising homological mirror symmetry.https://jhap.du.ac.ir/article_2060_be301b3153dd56873509f89810e68a05.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786220260131Holography and the Swampland: Constraints on Quantum Gravity from Holographic Principles3555205510.22128/jhap.2025.3117.1152ENSudhaker UpadhyayDepartment of Physics, K.L.S.

In parallel, holography, and particularly the AdS/CFT correspondence, offers a non-perturbative definition of quantum gravity in asymptotically anti-de Sitter (AdS) spacetimes. In this paper, we explore the Swampland Conjectures through the lens of holography, focusing on how holographic consistency conditions, such as the convexity of the conformal field theory (CFT) spectrum, the averaged null energy condition (ANEC), and the modular bootstrap, map onto Swampland constraints in the bulk. We argue that the holographic principle provides a geometric realization of Swampland bounds, particularly on scalar field potentials and the absence of long-lived de Sitter vacua. Finally, we discuss how the emergent bulk locality in AdS/CFT provides evidence that the Swampland conjectures may themselves be manifestations of deeper holographic consistency conditions.https://jhap.du.ac.ir/article_2055_e2502cf0a129ce5ea600b0397cf0d313.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786220260101Magnetic AdS Black Holes: Topological Thermodynamics and Photon Sphere Analysis5669205310.22128/jhap.2025.3111.1149ENSaeed Noori GashtiDepartment of Physics, Faculty of Basic Sciences, University of Mazandaran P.

Alimjan Str. 14, Urgench 221100, UzbekistanJournal Article20251027We study the thermodynamic topology of magnetic AdS black holes, with a focus on topological charges and their configurations. Zero points in the system’s vector field correspond to topological charges, whose numbers change with key parameters. Across all free parameter ranges, the total topological charge consistently matches that of AdS Reissner-Nordström black holes. Also, we analyze photon spheres, revealing their role in black hole structures and resilience to parameter variations. Unstable photon spheres show distinctive signatures, showing black holes' spacetime geometry. This topological framework offers a systematic approach to understanding black hole stability, phase transitions, and potential astrophysical phenomena.https://jhap.du.ac.ir/article_2053_ec597bc7d53b8c00833d63ec3aa8a560.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786220260131Holographic Phase Transition of AdS Black Hole Solution Coupled with Nonlinear Electrodynamics7086205410.22128/jhap.2025.3146.1160ENTalvinder SinghDepartment of Physics, Institute of Applied Science and Humanities, GLA University, Mathura 281406, IndiaDharm Veer SinghDepartment of Physics, Institute of Applied Science and Humanities, GLA University, Mathura 281406, India0000-0002-8101-2745Journal Article20251116This study presents a novel $AdS$ black hole (BH) solution coupled with NLED and a cloud of string. Our solution interpolates to the $AdS$ Letailier BH in the absence of magnetic monopole charge ($q$) and deviation parameter ($k$), $AdS$ Hayward Letailier BH when in the absence of deviation parameter, $AdS$ regular Letailier BH in the absence of magnetic monopole charge, as well as Schwarzschild BH in the limit of $q = 0, k = 0, a = 0$. We have studied the horizon structure of the obtained solution; the BH has two horizons (event and Cauchy) in contrast with the Schwarzschild BH. The thermodynamic quantities associated with the BH are modified in the presence of magnetic monopole charge, cloud of string parameter, and a deviation parameter. The first law of BH thermodynamics is modified in the presence of magnetic monopole charge and deviation parameter. Additionally, we examine the thermodynamics of the $AdS$ Letailier regular BH solution, considering the cosmological constant ($\Lambda$) as thermodynamic pressure ($P$), and analyze the critical points and phase structure of the BH within an extended phase space. The plot of Gibbs free energy against temperature exhibits a swallow-tail behaviour, signifying a first-order phase transition that concludes at a second-order phase transition.https://jhap.du.ac.ir/article_2054_6b1af0a7f53a1f1a64c38e22ef6e7fff.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786220260131Thermodynamic Structure of Einstein-Gauss-Bonnet Regular Black Holes Coupled with Cloud of String87103205910.22128/jhap.2025.3148.1162ENVijay KumarMishraDepartment Physics, Institute of Applied Sciences and Humanities, GLA University, Mathura 281406 Uttar Pradesh, IndiaManish PandeyDepartment of Civil Engineering, Faculty of Engineering, Marwadi University, Rajkot, Gujarat 360003, IndiaJournal Article20251116We construct several black holes coupled with the nonlinear electrodynamics (NLED) known as a regular black hole, which becomes Maxwell's theory in the weak field limit. We present an exact regular black hole solution in the presence of a cloud of strings (CoS), and Einstein-Gauss-Bonnet (EGB) gravity. We study the global properties of the solutions and derive the corrected first law of thermodynamics, because the first law of thermodynamics is modified in the presence of NLED. In addition, we have studied the thermodynamics properties associated with the EGB regular black hole solution, the thermodynamic quantities (Mass, Temperature, Entropy, Heat Capacity and Free Energy) is change in the presence of NLED, CoS, and EGB parameter.https://jhap.du.ac.ir/article_2059_17c03becd0dab6b7e20132d7e9120dd6.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786220260131Gravitational Lensing by Kalb-Ramond Black Holes Coupled by Nonlinear Electrodynamics104118205810.22128/jhap.2025.3147.1161ENAadya SharmaDepartment of Physics, Institute of Applied Science and Humanities, GLA University, Mathura 281406, India0009-0006-5984-2108Bablu .Department of Physics, Institute of Applied Science and Humanities, GLA University, Mathura 281406, IndiaDharm Veer SinghDepartment of Physics, Institute of Applied Science and Humanities, GLA University, Mathura 281406, India0000-0002-8101-2745Journal Article20251116In this paper, we study the black hole solution coupled with the Kalb–Ramond (KR) field and nonlinear electrodynamics (NLED). The obtained black hole solutions interpolate between a Kalb-Ramond black hole in the absence of NLED and the Schwarzschild black hole in the limit of vanishing KR and NLED field. We study gravitational lensing by a black hole solution.

While computable structures such as solutions of the Einstein equations are realized independently of human description, we argue that G\"odelian non-algorithmic truths are likewise objectively actualized in physical reality. Although the Lucas-Penrose argument is superficially similar, it concerns the nature of human consciousness, whereas our claim is fundamentally different in scope. We apply this reasoning to the structure of reality itself, independent of human consciousness. Consequently, objections based on the possible inconsistency of human reasoning are not applicable here, since assuming nature itself to be inconsistent is not tenable, as it would collapse the distinction between true and false physical claims.https://jhap.du.ac.ir/article_2056_ac564b51d75f864fe41ef325a4f449e2.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786220260131Discussion on Consequences of Undecidability in Physics on the Theory of Everything125131205710.22128/jhap.2025.3127.1157ENWeicheng CuiZhejiang Engineering Research Center of Micro/Nano-Photonic/Electronic System Integration, Westlake University, Hangzhou, Zhejiang 310030, China;

(published in the Journal of Holographic Applied Physics, Volume 5, Issue 2, Pages 10–21). It fully endorses the core conclusions put forward in the original work: purely algorithmic frameworks (such as algorithmic quantum gravity, FQG) are inadequate for formulating a Theory of Everything (ToE), as supported by the theoretical foundations of Gödel, Tarski, and Chaitin; the "Meta-Theory of Everything" (MToE) provides an effective solution to address undecidable phenomena in physics; and the universe cannot be a product of simulation. However, this paper dissents from the original authors' pursuit of a "complete and consistent" effective theory. Given that completeness and consistency are sometimes mutually exclusive in nature, it advocates for a reframing of the MToE. The revised framework should prioritize logical consistency while explicitly abandoning the unattainable requirement of completeness.https://jhap.du.ac.ir/article_2057_05c12e4ed27610336e8f229dbeb46453.pdf
