Non-analyticity of holographic Rényi entropy in Lovelock gravity
V. Giangreco M. Puletti, R. Pourhasan
We compute holographic Rényi entropies for spherical entangling surfaces on the boundary while considering third order Lovelock gravity with negative cosmological constant in the b…
Monopole correlation functions and holographic phases of matter in 2+1 dimensions
T. Alho, V. Giangreco M. Puletti, R. Pourhasan +1
The strong coupling dynamics of a 2+1 dimensional U(1) gauge theory coupled to charged matter is holographically modeled via a top-down construction with intersecting D3- and D5-br…
Spacetime Entanglement with f(R) Gravity
Razieh Pourhasan
We study the entanglement entropy of a general region in a theory of induced gravity using holographic calculations. In particular we use holographic entanglement entropy prescript…
Geometric RG Flow
Steven Jackson, Razieh Pourhasan, Herman Verlinde
We define geometric RG flow equations that specify the scale dependence of the renormalized effective action Gamma[g] and the geometric entanglement entropy S[x] of a QFT, consider…
Out of the White Hole: A Holographic Origin for the Big Bang
Razieh Pourhasan, Niayesh Afshordi, Robert B. Mann
While most of the singularities of General Relativity are expected to be safely hidden behind event horizons by the cosmic censorship conjecture, we happen to live in the causal fu…
On Spacetime Entanglement
Robert C. Myers, Razieh Pourhasan, Michael Smolkin
We examine the idea that in quantum gravity, the entanglement entropy of a general region should be finite and the leading contribution is given by the Bekenstein-Hawking area law.…
Entropy balance in holographic superconductors
Sean A. Hartnoll, Razieh Pourhasan
In systems undergoing second order phase transitions, the temperature integral of the specific heat over temperature from zero to the critical temperature is the same in both the n…
Gauss-Bonnet Black Holes and Heavy Fermion Metals
R. B. Mann, R. Pourhasan
We consider charged black holes in Einstein-Gauss-Bonnet Gravity with Lifshitz boundary conditions. We find that this class of models can reproduce the anomalous specific heat of c…
