Revisiting the static spherically symmetric solutions of gravity with a conformally coupled scalar field
Sourya Ray
We revisit the static spherically symmetric solutions of Einstein's General Relativity with a conformally coupled scalar field in arbitrary dimensions. Using a four rank tensor int…
Lie Symmetries of Non-Relativistic and Relativistic Motions
Carles Batlle, Joaquim Gomis, Sourya Ray +1
We study the Lie symmetries of non-relativistic and relativistic higher order constant motions, in spatial dimensions, like constant acceleration, constant rate-of-change -of-a…
Black Hole Enthalpy and Scalar Fields
David Kastor, Sourya Ray, Jennie Traschen
The mass of an AdS black hole represents its enthalpy, which in addition to internal energy, generally includes the energy required to assemble the system in its environment. In th…
Lovelock Branes
David Kastor, Sourya Ray, Jennie Traschen
We study the problem of finding brane-like solutions to Lovelock gravity, adopting a general approach to establish conditions that a lower dimensional base metric must satisfy in o…
Genuine Cosmic Hair
David Kastor, Sourya Ray, Jennie Traschen
We show that asymptotically future deSitter (AFdS) spacetimes carry 'genuine' cosmic hair; information that is analogous to the mass and angular momentum of asymptotically flat spa…
Extended First Law for Entanglement Entropy in Lovelock Gravity
David Kastor, Sourya Ray, Jennie Traschen
The first law for the holographic entanglement entropy of spheres in a boundary CFT with a bulk Lovelock dual is extended to include variations of the bulk Lovelock coupling consta…
