1. On the time dependence of holographic complexity in a dynamical Einstein-dilaton model / Mahapatra, Subhash ; Roy, Pratim
We study the holographic “complexity = action” (CA) and “complexity = volume” (CV) proposals in Einstein-dilaton gravity in all spacetime dimensions. [...]

2. Interplay between the holographic QCD phase diagram and entanglement entropy / Dudal, David ; Mahapatra, Subhash
In earlier work, we introduced a dynamical Einstein-Maxwell-dilaton model which mimics essential features of QCD (thermodynamics) below and above deconfinement. [...]

3. Logarithmic black hole entropy corrections and holographic Rényi entropy / Mahapatra, Subhash
The entanglement and Rényi entropies for spherical entangling surfaces in CFTs with gravity duals can be explicitly calculated by mapping these entropies first to the thermal entropy on hyperbolic space and then, using the AdS/CFT correspondence, to the Wald entropy of topological black holes. [...]

4. Confining gauge theories and holographic entanglement entropy with a magnetic field / Dudal, David ; Mahapatra, Subhash
We consider the soft wall model for a heuristic holographical modelling of a confining gauge theory and discuss how the introduction of a (constant) magnetic field influences the (de)confinement phase structure. [...]
