Mutual information, islands in black holes and the Page curve
Ashis Saha, Sunandan Gangopadhyay, Jyoti Prasad Saha
The role played by the mutual information of subsystems on the Page curve is explored in this paper. With the total system consisting of the black hole and radiation, together with…
Generalized entanglement temperature and entanglement Smarr relation
Ashis Saha, Sunandan Gangopadhyay, Jyoti Prasad Saha
We observe that in presence of excitation, a thermodynamic Smarr like relation corresponding to a generalized entanglement temperature () can be holographically obtained for t…
Holographic entanglement entropy and generalized entanglement temperature
Ashis Saha, Sunandan Gangopadhyay, Jyoti Prasad Saha
In this work we study the flow of holographic entanglement entropy in dimensions in the gauge/gravity duality set up. We observe that a generalized entanglement temperat…
Self-adjoint extension for Maxwell-Chern-Simons model in long wavelength limit
Pinaki Patra, Jyoti Prasad Saha, Kalpana Biswas
In the long wavelength limit, Maxwell-Chern-Simmon model and the dynamics of a particle in a plane under an external magnetic field perpendicular to that plane are identical. The s…
Modified Hamiltonian formalism for Regge Teitelboim Cosmology
Pinaki Patra, Md. Raju, Gargi Manna +1
The Ostrogradski approach for the Hamiltonian formalism of higher derivative theory is not satisfactory because of the reason that the Lagrangian cannot be viewed as a function on…
Quantum Restoration of Broken Symmetry in one Dimensional Loop Space
Pinaki Patra, Tanmay Mandal, Jyoti Prasad Saha
For 1 Dimensional loop space, a nonlinear nonlocal transformation of fields is given to make the action of the self-interacting quantum field to the free one. A specific type of Cl…
