Analog of Superradiance effect in BEC
We investigate the scattering of phase oscillation of Bose-Einstein Condensate by a ’draining of bathtub’ type fluid motion. We derive a relation between the reflection and transmission coefficients which exhibits existence of analog of ’Superradiance effect’ in BEC vortex with sink.

Submitted for the MAR05 Meeting of The American Physical Society Surface Waves at the Mott Insulator-Superfluid interface for confined BEC EROS MARIANI, ADY STERN, Department of Condensed Matter Physics, The Weizmann Institute of Science, 76100 Rehovot (Israel) — Bose Einstein Condensates in optical lattices under an external confinement are expected to form Superfluid and Mott-Insulating domai...
متن کاملBec and the New World of Coherent Matter Waves
After decades of effort to produce an atomic Bose condensate, this was finally achieved in June, 1995 in a laser-cooled magnetically trapped gas of Rb atoms by Eric Cornell and Carl Wieman at JILA (University of Colorado and N.I.S.T.). As of July, 1999 (4 years later), there are now over 20 experimental groups around the world who can routinely produce and study such atomic Bose condensates. In...
متن کاملHawking Effect in 2-D String Theory
We use the matrix model to study the final state resulting from a coherent high energy pulse in 2-d string theory at large string coupling. We show that the outgoing signal produced via reflection off the potential has a thermal spectrum, with the correct temperature and profile to be identified with Hawking radiation. We confirm its origin as geometrical radiation produced by the gravitational...
متن کاملThe Hawking effect for massive particles
This paper describes a particularly transparent derivation of the Hawking effect for massive particles in black holes. The calculations are performed with the help of Painlevé-Gullstrand’s coordinates which are associated with a radially free-falling observer that starts at rest from infinity. It is shown that if the energy per unit rest mass, e, is assumed to be related to the the Killing cons...
