Krylov Complexity and Spectral Form Factor for Noisy Random Matrix Models
Arpan Bhattacharyya, S. Shajidul Haque, Ghadir Jafari +2
We study the spectral properties of two classes of random matrix models: non-Gaussian RMT with quartic and sextic potentials, and RMT with Gaussian noise. We compute and analyze th…
On Free Energy for Deformed JT Gravity
Mohsen Alishahiha, Amin Faraji Astaneh, Ghadir Jafari +2
In this paper, we study a particular deformation of the Jackiw-Teitelboim gravity recently considered by Maxfield, Turiaci and independently by Witten. We will compute the partitio…
Holographic complexity of Born-Infeld gravity
Hamid R. Bakhtiarizadeh, Ghadir Jafari
We investigate the duality conjecture "Complexity=Action" (CA) for Born-Infeld (BI) gravity model and derive the growth rate of its action within the Wheeler-DeWitt (WDW) patch, wh…
A geometric look at the objective gravitational wave function reduction
Faramarz Rahmani, Mehdi Golshani, Ghadir Jafari
In ref [1], a criterion has been derived for the objective wave function reduction through the Shrödinger-Newton equation. In this paper, we shall derive that criterion by using th…
Gravitational reduction of the wave function based on Bohmian quantum potential
Faramarz Rahmani, Mehdi Golshani, Ghadir Jafari
In objective gravitational reduction of the wave function of a quantum system, the classical limit of the system is obtained in terms of the objective properties of the system. On…
On the first law of holographic complexity
S. Sedigheh Hashemi, Ghadir Jafari, Ali Naseh
In this paper, we examine the proposed first law of holographic complexity through studying different perturbations around various spacetime backgrounds. We present a general expre…
Path Integral Optimization for Deformation
Ghadir Jafari, Ali Naseh, Hamed Zolfi
We use the path integral optimization approach of Caputa, kundu, Miyaji, Takayanagi and Watanabe to find the time slice of geometries dual to vacuum, primary and thermal states in…
More on Complexity in Finite Cut Off Geometry
S. Sedigheh Hashemi, Ghadir Jafari, Ali Naseh +1
It has been recently proposed that late time behavior of holographic complexity in a uncharged black brane solution of Einstein-Hilbert theory with boundary cut off is consistent w…
Instability of BTZ black holes in parity-even massive gravity
Ghadir Jafari, Hesam Soltanpanahi
We investigate the linearized equations of motion in three dimensional Born-Infeld gravity theory. Motivated by this model, we calculate the quasinormal modes of BTZ black hole sol…
Stress Tensor on Null Boundaries
Ghadir Jafari
Using the Brown-York prescription for the definition of quasilocal gravitational energy-momentum tensor on a boundary and also complete canonical structure on a null boundary which…
On variational principle and canonical structure of gravitational theory in double-foliation formalism
Sajad Aghapour, Ghadir Jafari, Mehdi Golshani
In this paper, we analyze the variation of the gravitational action on a bounded region of spacetime whose boundary contains segments with various characters, including null. We de…
Static spherically symmetric black holes in de Rham-Gabadadze-Tolley massive gravity in arbitrary dimensions
Ghadir Jafari, M. R. Setare, Hamid R. Bakhtiarizadeh
This article is devoted to static spherically symmetric black hole solutions of dRGT (de Rham-Gabadadze-Tolley) massive gravity in the presence of cosmological constant. The unitar…
Linearized Holographic Isotropization at Finite Coupling
Mahdi Atashi, Kazem Bitaghsir Fadafan, Ghadir Jafari
We study holographic isotropization of an anisotropic homogeneous non-Abelian strongly coupled plasma in the presence of Gauss-Bonnet corrections. It was verified before that one c…
Gravitational Couplings on D-brane Revisited
Ahmad Ghodsi, Ghadir Jafari
Gravitational couplings in bulk space-time include those terms which are fixed by scattering amplitude of strings and ambiguous terms that are coming from the field redefinitions.…
On T-duality of -corrections to DBI action at all orders of gauge field
Ahmad Ghodsi, Mohammad R. Garousi, Ghadir Jafari
Recently, it has been observed that in a T-duality invariant world-volume theory in flat spacetime, all orders of gauge field strength and all orders of the D-brane velocity appear…
T-duality of D-brane action at order in bosonic string theory
Mohammad R. Garousi, Ahmad Ghodsi, Tooraj Houri +1
In bosonic string theory, it is known that the Buscher rules for the T-duality transformations receive quantum corrections at order . In this paper, we use the consistency of t…
