Entangled spins and ghost-spins
Dileep P. Jatkar, K. Narayan
We study patterns of quantum entanglement in systems of spins and ghost-spins regarding them as simple quantum mechanical toy models for theories containing negative norm states. W…

Hyperscaling violation and the shear diffusion constant
Kedar S. Kolekar, Debangshu Mukherjee, K. Narayan
We consider holographic theories in bulk -dimensions with Lifshitz and hyperscaling violating exponents at finite temperature. By studying shear gravitational modes in…

On extremal surfaces and entanglement entropy in some ghost CFTs
K. Narayan
In arXiv:1501.03019 [hep-th], the areas of certain complex extremal surfaces in de Sitter space were found to have resemblance with entanglement entropy in appropriate dual Euclide…
