Calendar of Physics Talks Vienna
| Speaker: | Massimiliano Rinaldi (Université de Genève) |
| Abstract: | In 1981 a seminal paper by W. Unruh showed that it is possible to generate thermal emission in a superfluid, which has the same characteristics of the Hawking radiation emitted by astrophysical black holes. This analogy opened up the possibility to observe the Hawking radiation in a laboratory, in a variety of condensed matter systems. In recent years, this possibility has become a feasible reality, boosting the interest in the so-called analogue models of gravity. In this talk, I will first review the fundamentals of Hawking radiation in both astrophysical and condensed matter systems, focussing in particular on Bose-Einstein condensates. Then I will discuss some recent developments and future perspectives of this fascinating analogy. Schedule Overview |

| Membrane Paradigm in f(R) gravity |
| Speaker: | Sudipta Sarkar (IUCAA, Pune) |
| Abstract: | The membrane paradigm is the remarkable view that, to an external observer, a black hole appears to behave exactly like a dynamical fluid membrane, obeying pre-relativistic equations. We extend the existing membrane formalism for General relativity to black holes in any general f(R)-theory of gravity and derive the stress tensor and various transport coefficients of the membrane fluid.
The membrane turns out to behave like a non-Newtonian fluid except for the case of General Relativity. We also derive dynamical equations describing the fluid membrane. This result establishes the general analogy of the properties of black hole horizon with fluid mechanics beyond General Relativity to any general f(R) gravity theory.
