Closed timelike curves in modified theories of gravity
Agnik Sen Roy, Sashideep Gutti, Shailesh Kulkarni
We study closed timelike curves (CTCs) in three rotating spacetimes arising in modified gravity: the tidally charged braneworld black hole, the Kerr-Newman black hole in Rastall gr…
Extended Near Horizon Symmetries of Extremal BTZ Black Holes in 3D Massive Gravity
Debojyoti Ballav, Shailesh Kulkarni
We study the asymptotic symmetries of near-horizon extremal BTZ black holes in higher derivative theories of gravity, such as New Massive Gravity and Topological Massive Gravity. B…
Ecosystem for Closed Timelike Curves: An Energy Conditions Perspective
Sashideep Gutti, Shailesh Kulkarni, Vaishak Prasad +1
In this article, we explore the relationship between the existence of closed timelike curves and energy conditions that occur in the Kerr-Newman spacetime. To quantify the dependen…
"Striped" Rectangular Rigid Box with Hermitian and non-Hermitian Symmetric Potentials
Shailesh Kulkarni, Rajeev K. Pathak
Eigenspectra of a spinless quantum particle trapped inside a rigid, rectangular, two-dimensional (2D) box subject to diverse inner potential distributions are investigated under he…
Generalized ADT charges and asymptotic symmetry algebra
Shailesh Kulkarni
Using the expressions for generalized ADT current and potential in a self consistent manner, we derive the asymptotic symmetry algebra on AdS and the near horizon extremal BTZ…
Quasilocal Conserved Charges with a Gravitational Chern-Simons Term
Wontae Kim, Shailesh Kulkarni, Sang-Heon Yi
We extend our recent work on the quasilocal formulation of conserved charges to a theory of gravity containing a gravitational Chern-Simons term. As an application of our formulati…
