Bounds on GUP parameters from GW150914 and GW190521
Ashmita Das, Saurya Das, Noor R. Mansour +1
We compute bounds on the GUP parameters for two versions of GUP using gravitational wave data from the events GW150914 and GW190521. The speed of the graviton and photon are calcul…
Discreteness of Space from GUP in Strong Gravitational Fields
Ashmita Das, Saurya Das, Elias C. Vagenas
A large class of quantum theories of gravity show that the Heisenberg's uncertainty principle is modified to the "Generalised Uncertainty Principle" (GUP) near the Planckian scale.…
Conformal Vacuum and Fluctuation-Dissipation in de-Sitter Universe and Black Hole Spacetimes
Ashmita Das, Surojit Dalui, Chandramouli Chowdhury +1
In the studies of quantum field theory in curved spacetime, the ambiguous concept of vacuum state and the particle content is a long-standing debatable aspect. So far it is well kn…
Noether and Abbott-Deser-Tekin conserved quantities in scalar-tensor theory of gravity both in Jordan and Einstein frames
Krishnakanta Bhattacharya, Ashmita Das, Bibhas Ranjan Majhi
We revisit the thermodynamic aspects of the scalar-tensor theory of gravity in the Jordan and in the Einstein frame. Examining the {\it missing links} of this theory carefully, we…
