Linearized warp drive and the energy conditions
Francisco S. N. Lobo, Matt Visser
''Warp drive'' spacetimes are useful as ''gedanken-experiments'' and as a theoretician's probe of the foundations of general relativity. Applying linearized gravity to the weak-fie…
Effective refractive index tensor for weak field gravity
Petarpa Boonserm, Celine Cattoen, Tristan Faber +2
Gravitational lensing in a weak but otherwise arbitrary gravitational field can be described in terms of a 3 x 3 tensor, the "effective refractive index". If the sources generating…
Massive phonon modes from a BEC-based analog model
Matt Visser, Silke Weinfurtner
Two-component BECs subject to laser-induced coupling exhibit a complicated spectrum of excitations, which can be viewed as two interacting phonon modes. We study the conditions req…
Universality of the subsolar mass distribution from critical gravitational collapse
Matt Visser, Nicolas Yunes
Self-similarity induced by critical gravitational collapse is used as a paradigm to probe the mass distribution of subsolar objects. At large mass (solar mass and above) there is w…
Nonlinear realizations of Lorentz symmetry
Matt Visser
This paper withdrawn -- it has been revised and merged with gr-qc/0205067 (Conservation laws in "Doubly Special Relativities"; Simon Judes and Matt Visser)
On the space-time curvature experienced by quasiparticle excitations in the Painleve-Gullstrand effective geometry
Uwe R. Fischer, Matt Visser
We consider quasiparticle propagation in constant-speed-of-sound (iso-tachic) and almost incompressible (iso-pycnal) hydrodynamic flows, using the technical machinery of general re…
