Entanglement entropy for non-zero genus topologies
S. Santhosh Kumar, Suman Ghosh, S. Shankaranarayanan
Over the last three decades entanglement entropy has been obtained for quantum fields propagating in genus zero topologies (Spheres). For scalar fields propagating in these topolog…

Entanglement signatures of phase transition in higher-derivative quantum field theories
Suman Ghosh, S. Shankaranarayanan
We show that the variation of the ground state entanglement in linear, higher spatial derivatives field theories at zero-temperature have signatures of phase transition. Around the…

Particle creation in the presence of a warped extra dimension
Suman Ghosh, Sayan Kar
Particle creation in spacetimes with a warped extra dimension is studied. In particular, we investigate the dynamics of a conformally coupled, massless scalar field in a five dimen…
