No-slip Billiards with Particles of Variable Mass Distribution
J. Ahmed, C. Cox, B. Wang
Astute variations in the geometry of mathematical billiard tables have been and continue to be a source of understanding their wide range of dynamical behaviors, from regular to ch…
Black hole chemistry and holography in generalized quasi-topological gravity
Mozhgan Mir, Robie A. Hennigar, Jamil Ahmed +1
We investigate the thermodynamics of AdS black holes in Generalized Quasitopological Gravity with and without electric charge, concentrating on the version of the theory that is cu…
Greybody factor of scalar fields from black strings
Jamil Ahmed, K. Saifullah
The greybody factor of massless, uncharged scalar fields is studied in the background of cylindrically symmetric spacetimes, in the low-energy approximation. We discuss two cases.…
Quintessential Quartic Quasi-topological Quartet
Jamil Ahmed, Robie A. Hennigar, Robert B. Mann +1
We construct the quartic version of generalized quasi-topological gravity, which was recently constructed to cubic order in arXiv: 1703.01631. This class of theories includes Lovel…
Greybody factor of scalar field from Reissner-Nordstrom-de Sitter black hole
Jamil Ahmed, K. Saifullah
In this work we derive a general expression for the greybody factor of non-minimally coupled scalar fields in Reissner-Nordström-de Sitter spacetime in low frequency approximation.…
Hawking radiation of Dirac particles from black strings
Jamil Ahmed, K. Saifullah
Hawking radiation has been studied as a phenomenon of quantum tunneling in different black holes. In this paper we extend this semi-classical approach to cylindrically symmetric bl…
