Who Writes the Gravitational Second Law of Thermodynamics?
V. R. Shajiee, M. M. Sheikh-Jabbari, V. Taghiloo
We define gravitational entropy as the manifestly integrable surface charge associated with local transverse Lorentz boosts, entirely bypassing the conventional reliance on spaceti…
Dynamical Entropy Is a Noether Charge
V. R. Shajiee, M. M. Sheikh-Jabbari, V. Taghiloo
Black hole thermodynamics for generic dynamical, non-equilibrium regimes remains a fundamental challenge. We establish dynamical entropy as the Noether charge associated with a gen…
Gravitational Entropy And The Second Law of Thermodynamics for Causal Observers
V. R. Shajiee, M. M. Sheikh-Jabbari, V. Taghiloo
It is well established that black holes possess entropy and behave as thermodynamic systems. Associating entropy with gravitational fields has not remained limited to black holes,…
Counting Black Hole Microstates at Future Null Infinity
Vahid Reza Shajiee
We propose a black hole microstate counting method based on the canonical quantization of the asymptotic symmetries of a two-dimensional dilaton-gravity system at future null infin…
Dominant Spacetime in Three Dimensional de Sitter Gravity
Reza Fareghbal, Vahid Reza Shajiee
In three dimensions, Kerr-de Sitter spacetime as a solution of Einstein gravity with positive cosmological constant has a single cosmological horizon. The flat-space limit (zero co…
Electroweak Phase Transition, Gravitational Waves and Dark Matter in Two Scalar Singlet Extension of The Standard Model
Vahid Reza Shajiee, Ali Tofighi
In this paper, the electroweak phase transition, the gravitational waves and the dark matter issues are investigated in two scalar singlet extension of the standard model. The dete…
Mass of the Stabilized Radion in the Limit of Finite Quartic Coupling
Ali Tofighi, Vahid Reza Shajiee
We present an exact treatment of the modulus stabilization condition with the general boundary conditions of the bulk scalar field in the Randall-Sundrum model. We find analytical…
The Schwarzschild/CFT Correspondence: Weyl Rescaled Case
Jafar Sadeghi, Vahid Reza Shajiee
In this work, the CFT dual of the Schwarzschild black hole is investigated. A Weyl rescaling factor is presented, so that the Weyl rescaled Schwarzschild metric, after a coordinate…
