https://jhap.du.ac.ir/article_338.html
The gauge/gravity duality, combined with information from lattice QCD, nuclear theory, and perturbative QCD, can be used to constrain the equation of state of hot and dense QCD. I discuss an approach based on the holographic V-QCD model. I start by reviewing the results from the construction of the V-QCD baryon as a soliton of the gauge fields in the model.Then I discuss implementing nuclear matter in the model by using a homogeneous approach. The model predicts a strongly first order phase transition from nuclear to quark matter with a critical endpoint. By using the model in state-of-the-art simulations of neutron star binaries with parameters consistent with GW170817, I study the formation of quark matter during the merger process.Implications of quantum corrections on the thermodynamics of charged AdS black hole
https://jhap.du.ac.ir/article_341.html
This paper investigates the quantum corrections to the thermodynamic properties of charged AdS black holes. The corrections that we examine arise because of quantum fluctuations in space-time geometry, which corresponds to thermal fluctuations in thermodynamics. First, we compute the leading order corrections to entropy, and later we plot the corrected entropy as a function of event horizon radius for various values of correction parameter alphato explore the effect of quantum corrections on the entropy of black holes analytically.On-shell Equation of the Lorentzian Classicalized Holographic Tensor Network
https://jhap.du.ac.ir/article_340.html
In the Lorentzian classicalized holographic tensor network (cHTN), we derive its relativistic on-shell equation from its Lorentzian action in the presence of a relativistic massive particle in the bulk spacetime: $-\sigma \hbar \theta=Mc^2$.Here, $\sigma$ is the von Neumann entropy of the cHTN per site in nats, $\theta$ is the real-proper-time expansion of the cHTN defined along the world line of the particle, and $M$ is the non-zero mass of the particle.We explain the physical properties, interpretation, and consequences of this equation.Specifically, from this equation we derive the properties of the on-shell proper acceleration of another massive particle in the bulk spacetime as those of the gravitational acceleration induced by the original massive particle.Hawking Radiation as tunnelling from dilatonic BTZ black hole
https://jhap.du.ac.ir/article_355.html
In this paper, we study the Hawking radiation for a dilatonic BTZ black hole solution and derive the transmission probability of tunnelling through the barrier of the event horizon. Furthermore, we discuss the black hole chemistry of the black hole solution under the effect of thermal fluctuation and find that the thermal fluctuation plays a significant role for the black hole with small horizon radius.Non-perturbative corrections of shear viscosity to entropy ratio
https://jhap.du.ac.ir/article_354.html
Shear viscosity to entropy ratio has a universal lower bound which may be violated under some effects. This paper would like to consider non-perturbative quantum corrections on the mentioned ratio in a STU black hole background. The STU model is a gravitational background that is the holographic dual of $N=4$ super Yang-Mills quark-gluon plasma with the chemical potential. Non-perturbative corrections to the black hole entropy emerge as an exponential term which may affect the shear viscosity to entropy ratio. All possibilities will study in this paper to extract the shear viscosity of a quark-gluon plasma. We find that the universal lower bound the shear viscosity to entropy ratio may be violated due to the non-perturbative corrections.Photonic and Plasmonic Encryption Based on Reflectionâ€“Transmission Reconfigurable Digital Coding Metasurface in Holographic images
https://jhap.du.ac.ir/article_353.html
Holography is a powerful technique that enables the manipulation of light waves and has been widely used in imaging, display technologies, and security. Recently, the field of plasmonics has emerged as a promising platform for creating holographic metasurfaces. Plasmonics holographic metasurfaces utilize plasmonic materials and engineered nanostructures to control and redirect light at the nanoscale. In this review, we provide a comprehensive overview of the recent developments in plasmonics holographic metasurfaces, including design principles, fabrication methods, and applications. We discuss different types of plasmonic materials and their properties for holographic metasurfaces, and explore the various approaches for engineering metasurfaces with desired functionalities. Furthermore, we summarize the state-of-the-art fabrication techniques, such as electron beam lithography and nanoimprint lithography, which are commonly employed for the fabrication of plasmonic holographic metasurfaces. Finally, we present the wide range of applications enabled by these metasurfaces, including beam shaping, holographic displays, optical encryption, and biosensing. This review aims to provide a comprehensive understanding of plasmonics holographic metasurfaces and their potential for future advancements in various disciplines.
