Standardized Cumulants of Flow Harmonic Fluctuations
Navid Abbasi, Davood Allahbakhshi, Ali Davody +1
The distribution of flow harmonics in heavy ion experiment can be characterized by standardized cumulants. We first model the ellipticity and power parameters of the elliptic-power…
Collective Excitations in Hot QCD Plasma
Navid Abbasi, Davood Allahbakhshi, Ali Davody +1
We study the long wavelength excitations in rotating QCD fluid in presence of an external magnetic field at finite vector and axial charge densities. We consider the fluctuations o…
From Schwinger Balls to Curved Space
Davood Allahbakhshi
It is shown that the Reissner-Nordstrom black hole is also a gravitational Schwinger ball. It is also shown that both massless and massive-particle gravitational Schwinger balls ar…
Black Holes Evaporate Non-Thermally
Davood Allahbakhshi
It is shown that the Hawking radiation and staying at the Schwarzschild state are not consistent for black holes as graviton balls. The only exception is the eternal black hole.
From Schwinger Balls to Black Holes
Davood Allahbakhshi
We have shown intriguing similarities between Schwinger balls and black holes. By considering black hole as a gravitational Schwinger ball, we have derived the Bekenstein-Hawking e…
Evaporation/Hadronization Correspondence
Davood Allahbakhshi
A holographic duality is proposed between black hole evaporation in the bulk and hadronization (confinement) in dual field theory. Information paradox is discussed in this duality.…
Do Horizons Exist?
Davood Allahbakhshi
Gravitational effective action is calculated to second order in transverse momentums for a planar asymptotically anti-de Sitter geometry by gauge fixing method. The first order bul…
Gravitational Effective Action: A New Method
Davood Allahbakhshi
A new method is introduced for doing calculations of quantum field theories in planar geometries which the metric depends on just one coordinate. In contrast to previous method, th…
Meson Life Time in the Anisotropic Quark-Gluon Plasma
Mohammad Ali-Akbari, Davood Allahbakhshi
In the hot (an)isotropic plasma the meson life time is defined as a time scale after which the meson dissociates. According to the gauge/gravity duality, this time can be ident…
Entanglement Thermodynamics
Mohsen Alishahiha, Davood Allahbakhshi, Ali Naseh
We study entanglement entropy for an excited state by making use of the proposed holographic description of the entanglement entropy. For a sufficiently small entangling region and…
Probing Fractionalized Charges
Mohsen Alishahiha, Davood Allahbakhshi
Inspired by holographic entanglement entropy, for geometries with non-zero abelian charges, we define a quantity which is sensitive to the background charges. One observes that the…
On Holography of Julia-Zee Dyon
Davood Allahbakhshi
The holographic dual of self gravitating Julia-Zee dyon is discussed. It is shown that the dual field theory is generally a field theory with a vortex condensate. The vacuum expect…
Holographic Phase Transition to Topological Dyons
Davood Allahbakhshi, Farhad Ardalan
The dynamical stability of a Julia-Zee solution in the AdS background in a four dimensional Einstein-Yang-Mills-Higgs theory is studied. We find that the model with a vanishing sca…
