Relativistic analogue of the D'Alembert principle of virtual displacements and the effective actions for the spherically-symmetric charged dust shell in General Relativity
Relativistic analogue D'Alembert principle of virtual displacements effective actions spherically-symmetric charged dust shell General Relativity

A simple and direct derivation of the variational principle and effective actions for a spherical charged dust shell in general relativity is offered. This principle is based on the relativistic versi...
Relativistic Bose-Einstein Condensates: a New System for Analogue Models of Gravity
relativistic Bose–Einstein condensate analogue models of gravity
2010/3/17
In this paper we propose to apply the analogy between gravity and condensed matter physics to relativistic Bose-Einstein condensates, i.e. condensates composed by relativistic constituents. While such...
