Real-Time Perturbation Theory in de Sitter Space
Kevin Goldstein, David A. Lowe
We consider scalar field theory in de Sitter space with a general vacuum invariant under the continuously connected symmetries of the de Sitter group. We begin by reviewing approac…
Stretched horizons, quasiparticles and quasinormal modes
Norihiro Iizuka, Daniel Kabat, Gilad Lifschytz +1
We propose that stretched horizons can be described in terms of a gas of non-interacting quasiparticles. The quasiparticles are unstable, with a lifetime set by the imaginary part…
Massive IIA String Theory and Matrix Theory Compactification
David A. Lowe, Horatiu Nastase, Sanjaye Ramgoolam
We propose a Matrix Theory approach to Romans' massive Type IIA supergravity. It is obtained by applying the procedure of Matrix Theory compactifications to Hull's proposal of the…
A note on alpha-vacua and interacting field theory in de Sitter space
Kevin Goldstein, David A. Lowe
We set up a consistent renormalizable perturbation theory of a scalar field in a nontrivial alpha vacuum in de Sitter space. Although one representation of the effective action inv…
Quasiparticle picture of black holes and the entropy--area relation
Norihiro Iizuka, Daniel Kabat, Gilad Lifschytz +1
We propose an effective description of 0-brane black holes, in which the black hole is modeled as a gas of non-interacting quasi-particles in the dual quantum mechanics. This simpl…
