By imposing structural and labeling constraints on the graph, it becomes possible to define the <em>n</em>-th position uniquely under neutrosophic fuzzy conditions. The variety of vertex labels and edge labels may coincide for more than one vertex, and a complete proof of existence is provided for the neutrosophic fuzzy labeling of the graphs discussed in this research. Using the neutrosophic fuzzy framework, all three forms of uncertainty in the labeling process are effectively represented. In this work, neutrosophic fuzzy graceful labeling is further connected to applications involving UV rays generated from a point source and holography. The uncertainty-handling capability of neutrosophic fuzzy labeling allows it to model imprecise intensity variations of UV radiation and the wave-interference patterns fundamental to holographic reconstruction. Thus, we develop a systematic method for applying the neutrosophic fuzzy framework to network design, routing, and optimization problems, as well as to holographic encoding where labeling consistency and uncertainty coexist. In addition to providing representations of the proposed neutrosophic fuzzy labeling framework for selected graph families, the paper demonstrates that labeling constraints can yield consistent graph while managing uncertainty associated with complex physical inputs such as UV propagation and holographic wave patterns. Compared to classical graceful labeling, neutrosophic fuzzy labeling offers enhanced capability to incorporate and handle imprecise, fluctuating, and partially known data. This study lays the foundation for future theoretical refinement and future algorithm development for neutrosophic fuzzy graph labeling with respect to the graceful constraints relating to optical modeling, UV radiation analysis, and holographic systems. https://jhap.du.ac.ir/article_2075_2e2c315b92a551730ef77f860e098025.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786320260319Imprints of Quantum Gravity on the Cooper-Frye Freeze-Out2030207410.22128/jhap.2026.3183.1173ENSameer Ahmad MirCanadian Quantum Research Center, 460 Doyle Ave 106, Kelowna, BC V1Y 0C2, Canada;

Using the linear Ali Das Vagenas GUP, which alters both the phase-space measure and the single-particle dispersion relation, the corresponding deformed particle current is constructed and its flux across a freeze-out hypersurface is evaluated. The resulting invariant spectrum acquires a momentum-dependent correction governed by a single dimensionless function that enhances high-momentum modes. For a static, homogeneous hypersurface the full expression can be written in closed analytic form, and the structure of the correction allows straightforward implementation in blast-wave-type models. The result is also directly relevant to holography-informed heavy-ion modeling, where gauge/gravity duality constrains the strongly coupled plasma dynamics but the conversion to hadron spectra is still performed through a Cooper-Frye freeze-out map. Our findings demonstrate that Planck-scale deformations of quantum mechanics can leave characteristic imprints on freeze-out observables, opening a novel avenue for constraining GUP scenarios with heavy-ion data.https://jhap.du.ac.ir/article_2074_9c60f4357530cc8907b90779f2a16a42.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786320260319Holographic Generation of Bessel–Gaussian Vortex Beams Using a Ring-Apertured Fork Grating and Topological Charge Measurement via an Astigmatic Grating3151207710.22128/jhap.2026.3169.1170ENSomaye FathollazadeDepartment of Physics, Institute for Advanced Studies in Basic Sciences (IASBS), Zanjan 45137-66731, Iran0009-0009-0899-9369Saifollah RasouliDepartment of Physics, Institute for Advanced Studies in Basic Sciences (IASBS), Zanjan 45137-66731, Iran;

The approach embeds a helical phase into a diffraction grating and then applies a ring-shaped transmission function. Embedding the helical phase converts the structure into a fork grating, while multiplication by the ring aperture ensures that the vortex beam produced in the first diffraction order evolves into a BGVB in the far field. The proposed holographic element was fabricated on a glass substrate using lithography, and illumination with a Gaussian beam of suitable waist generated a clear BGVB in the first diffraction order. The measured intensity profile shows excellent agreement with theoretical predictions. To determine the topological charge (TC), we employed an astigmatic grating with locally parallel grooves exhibiting second-order curvature. Introducing astigmatic aberration at an appropriate propagation distance produces elongated intensity fringes, and counting these fringes allows accurate determination of the TC. Numerical simulations and experimental measurements exhibit strong consistency, confirming the effectiveness of the proposed method.https://jhap.du.ac.ir/article_2077_5e96f5374fced097a233c35e30fc2ee8.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786320260301Casimir Energy Traversable Wormholes in Symmetric Teleparallel Gravity5271208010.22128/jhap.2025.3149.1163ENSadhana .Department of Mathematics, Institute of Applied Sciences and Humanities, GLA University, Mathura-281 406, Uttar Pradesh, IndiaShweta .Department of Mathematics, Institute of Applied Sciences and Humanities, GLA University, Mathura-281 406, Uttar Pradesh, IndiaAmbuj KumarMishraDepartment of Mathematics, Institute of Applied Sciences and Humanities, GLA University, Mathura-281 406, Uttar Pradesh, India0000-0001-9059-6108Journal Article20251116In recent years, research has concentrated on finding techniques to create traversable wormholes that circumvent the exotic matter problem or violate the null energy condition (NEC). Scientists are investigating alternate gravity theories and specific frameworks of ordinary matter that might potentially stabilize a wormhole throat, eliminating the necessity for negative energy density. Casimir energy, a quantum field theory phenomenon, provides a plausible option for producing traversable wormholes. Because Casimir energy can naturally produce specific regions of negative energy density, researchers are exploring how this artificial negative energy may function as the exotic matter needed to stabilize a wormhole's throat, potentially avoiding the need for theorized exotic matter. This research studies traversable wormhole geometries using Casimir energy as the source of the requisite exotic matter, looking at solutions within the framework of three different functional forms of $f(Q)$ gravity. The three functional forms taken are the power-law form, the inverse power-law form, and the logarithmic form for investigation. In all three cases, energy conditions are discussed. The anisotropy parameter and EoS parameter are analyzed to find a plausible solution for a traversable wormhole space-time.https://jhap.du.ac.ir/article_2080_bbd2070600cf0fb883b37354a88b0eeb.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786320260319Unified Entropic Dynamics Framework for Classical, and Quantum Wave Equations7296207910.22128/jhap.2025.3163.1167ENShahid NawazShaker High School, 445 Watervliet Shaker Rd, Latham, NY 12110, United States of AmericaMuhammad SaleemDepartment of Physics, Bellarmine University, 2001 Newburg Road, Louisville, KY 40205, United States of America0000-0002-6263-9059Muhammad ShahbazAnwarDepartment of Engineering \& Construction, School of Architecture, Computing \& Engineering, University of East London, London E16 2RD, United Kingdom;

Box 127788, United Arab Emirates0000-0003-2336-2859Journal Article20251125Entropic Dynamics (ED) provides a statistical–inferential foundation for physical laws, deriving motion and field equations from principles of entropy maximization rather than quantization postulates. The ED reconstructs quantum mechanics by treating the evolution of probability distributions on configuration space as driven by information constraints, yielding the Schrödinger equation as a non-dissipative diffusion process. Building on this foundation, the present work extends the ED framework into a Unified Entropic Dynamics (UED) formulation that encompasses classical, quantum, relativistic, thermodynamic, and gravitational phenomena within a single information-geometric principle. By maximizing entropy subject to constraints on diffusion, drift, and gauge covariance over a manifold endowed with a supermetric $H_{ab}$, we derive a universal field equation that merges the Fokker–Planck and Hamilton–Jacobi structures into one covariant form. When specialized to different dynamical variables, this equation reproduces the harmonic oscillator, Schrödinger, Maxwell, Klein–Gordon, and gravitational wave equations, thereby revealing a deep equivalence between probabilistic inference and dynamical law. The UED framework demonstrates that spacetime geometry, quantum coherence, and thermodynamic diffusion emerge as complementary expressions of the same entropic process—establishing a unified inferential foundation for both microscopic and macroscopic physics. In this formulation, energy, probability, and entropy are intertwined aspects of information geometry, providing a consistent inferential foundation for understanding classical, quantum, and gravitational dynamics as complementary expressions of a single entropic law.https://jhap.du.ac.ir/article_2079_b058e8fa4cf91588df69171079ff6e98.pdfDamghan University PressJournal of Holography Applications in Physics2783-47786320260319Particle Physics: A Crash Course for Mathematicians97136207810.22128/jhap.2025.3101.1146ENVeronica PasquarellaShanghai Institute for Mathematics and Interdisciplinary Sciences (SIMIS), Shanghai, 200433, China;
