Regularising the JNW and JMN naked singularities
Kunal Pal, Kuntal Pal, Pratim Roy +1
We extend the method of Simpson and Visser (SV) of regularising a black hole spacetime, to cases where the initial metric represents a globally naked singularity. We choose two par…
Aspects of entanglement in non-local field theories with fractional Laplacian
Pratim Roy
In recent years, various aspects of theoretical models with long range interactions have attracted attention, ranging from out-of-time-ordered correlators to entanglement. In the p…
On subregion action complexity in AdS and in the BTZ black hole
Roberto Auzzi, Stefano Baiguera, Andrea Legramandi +3
We analytically compute subsystem action complexity for a segment in the BTZ black hole background up to the finite term, and we find that it is equal to the sum of a linearly dive…
On the time dependence of holographic complexity in a dynamical Einstein-dilaton model
Subhash Mahapatra, Pratim Roy
We study the holographic "complexity=action'" (CA) and "complexity=volume" (CV) proposals in Einstein-dilaton gravity in all spacetime dimensions. We analytically construct an infi…
On subregion holographic complexity and renormalization group flows
Pratim Roy, Tapobrata Sarkar
We investigate subregion holographic complexity in the context of renormalization group flow geometries. We use both the Poincaŕe slicing and the Janus ansatz as holographic duals…
A Note on Subregion Holographic Complexity
Pratim Roy, Tapobrata Sarkar
The volume inside a Ryu-Takayanagi surface has been conjectured to be related to the complexity of subregions of the boundary field theory. Here, we study the behaviour of this vol…
