Multi-partite analysis of average-subsystem entropies
Ana Alonso-Serrano, Matt Visser
So-called average subsystem entropies are defined by first taking partial traces over some pure state to define density matrices, then calculating the subsystem entropies, and fina…
Stable gravastars - an alternative to black holes?
Matt Visser, David L. Wiltshire
The "gravastar" picture developed by Mazur and Mottola is one of a very small number of serious challenges to our usual conception of a "black hole". In the gravastar picture there…
Analogue models for FRW cosmologies
Carlos Barcelo, Stefano Liberati, Matt Visser
It is by now well known that various condensed matter systems may be used to mimic many of the kinematic aspects of general relativity, and in particular of curved-spacetime quantu…
Analog gravity from field theory normal modes?
Carlos Barcelo, Stefano Liberati, Matt Visser
We demonstrate that the emergence of a curved spacetime ``effective Lorentzian geometry'' is a common and generic result of linearizing a field theory around some non-trivial backg…
Analog gravity from Bose-Einstein condensates
Carlos Barcelo, Stefano Liberati, Matt Visser
We analyze prospects for the use of Bose-Einstein condensates as condensed-matter systems suitable for generating a generic ``effective metric'', and for mimicking kinematic aspect…
