On Butterfly effect in Higher Derivative Gravities
Mohsen Alishahiha, Ali Davody, Ali Naseh +1
We study butterfly effect in -dimensional gravitational theories containing terms quadratic in Ricci scalar and Ricci tensor. One observes that due to higher order derivatives i…
New Bi-Gravities
Amin Akhavan, Ali Naseh, Azadeh Nemati +1
We show that the problem of ghosts in critical gravity and its higher dimensional extensions can be resolved by giving dynamics to the symmetric rank two auxiliary field existing i…
Scale vs Conformal invariance from Entanglement Entropy
Ali Naseh
For a generic conformal field theory (CFT) in four dimensions, the scale anomaly dictates that the universal part of entanglement entropy across a sphere ($\mathcal{C}_{\text{univ}…
New Bi-Gravity from New Massive Garvity
Amin Akhavan, Mohsen Alishahiha, Ali Naseh +2
Using the action of three dimensional New Massive Gravity (NMG) we construct a new bi-gravity in three dimensions. This can be done by promoting the rank two auxiliary field appear…
Phase transitions in Bergshoeff-Hohm-Townsend Massive Gravity
Mahdis Ghodrati, Ali Naseh
We present the Hawking-Page phase diagrams in the Bergshoeff-Hohm-Townsend (BHT) massive gravity theory for different solutions, such as the phase transitions between vacuum $\text…
