Gravitational wave echoes from black holes in massive gravity
Ruifeng Dong, Dejan Stojkovic
Gravitational waves are rapidly becoming a very reliable tool for testing alternative theories of gravity. In particular, features in the gravitational wave emission during black h…
Quasi-normal modes of black holes in scalar-tensor theories with non-minimal derivative couplings
Ruifeng Dong, Jeremy Sakstein, Dejan Stojkovic
We study the quasi-normal modes of asymptotically anti-de Sitter black holes in a class of shift-symmetric Horndeski theories where a gravitational scalar is derivatively coupled t…
Gravity can significantly modify classical and quantum Poincare recurrence theorems
Ruifeng Dong, Dejan Stojkovic
Poincare recurrence theorem states that any finite system will come arbitrary close to its initial state after some very long but finite time. At the statistical level, this by its…
Gravitational wave production by Hawking radiation from rotating primordial black holes
Ruifeng Dong, William H. Kinney, Dejan Stojkovic
In this paper we analyze in detail a rarely discussed question of gravity wave production from evaporating primordial black holes. These black holes emit gravitons which are, at cl…
Greybody factors for a black hole in massive gravity
Ruifeng Dong, Dejan Stojkovic
An exact solution was recently found in the massive gravity theory having the form of Schwarzschild-dS black holes with some additional background fields. Hawking radiation will oc…
Symmetron Inflation
Ruifeng Dong, William H. Kinney, Dejan Stojkovic
We define a new inflationary scenario in which inflation starts naturally after the Big Bang when the energy density drops below some critical value. As a model, we use recently pr…
