Asyzygies, modular forms, and the superstring measure II
Eric D'Hoker, D. H. Phong
Precise factorization constraints are formulated for the three-loop superstring chiral measure, in the separating degeneration limit. Several natural Ansätze in terms of polynomial…
Asyzygies, modular forms, and the superstring measure I
Eric D'Hoker, D. H. Phong
The goal of this paper and of a subsequent continuation is to find some viable ansatze for the three-loop superstring chiral measure. For this, two alternative formulas are derived…
Decoupling in an expanding universe: backreaction barely constrains short distance effects in the CMB
Brian R. Greene, Koenraad Schalm, Gary Shiu +1
We clarify the status of transplanckian effects on the cosmic microwave background (CMB) anisotropy. We do so using the boundary effective action formalism of hep-th/0401164 which…
De Sitter Holography with a Finite Number of States
Maulik K. Parikh, Erik P. Verlinde
We investigate the possibility that, in a combined theory of quantum mechanics and gravity, de Sitter space is described by finitely many states. The notion of observer complementa…
Oscillating bounce solutions and vacuum tunneling in de Sitter spacetime
James C. Hackworth, Erick J. Weinberg
We study a class of oscillating bounce solutions to the Euclidean field equations for gravity coupled to a scalar field theory with two, possibly degenerate, vacua. In these soluti…
String windings in the early universe
Richard Easther, Brian R. Greene, Mark G. Jackson +1
We study string dynamics in the early universe. Our motivation is the proposal of Brandenberger and Vafa, that string winding modes may play a key role in decompactifying three spa…
A Secret Tunnel Through The Horizon
Maulik K. Parikh
Hawking radiation is often intuitively visualized as particles that have tunneled across the horizon. Yet, at first sight, it is not apparent where the barrier is. Here I show that…
Collisions of Cosmic F- and D-strings
Mark G. Jackson, Nicholas T. Jones, Joseph Polchinski
Recent work suggests that fundamental and Dirichlet strings, and their (p,q) bound states, may be observed as cosmic strings. The evolution of cosmic string networks, and therefore…
On the Construction of Asymmetric Orbifold Models
Kenichiro Aoki, Eric D'Hoker, D. H. Phong
Various asymmetric orbifold models based on chiral shifts and chiral reflections are investigated. Special attention is devoted to the consistency of the models with two fundamenta…
De Sitter Space With Finitely Many States: A Toy Story
Maulik K. Parikh, Erik Verlinde
The finite entropy of de Sitter space suggests that in a theory of quantum gravity there are only finitely many states. It has been argued that in this case there is no action of t…
Tuning Locked Inflation: Supergravity versus Phenomenology
Richard Easther, Justin Khoury, Koenraad Schalm
We analyze the cosmological consequences of locked inflation, a model recently proposed by Dvali and Kachru that can produce significant amounts of inflation without requiring slow…
Energy Conservation and Hawking Radiation
Maulik K. Parikh
The conservation of energy implies that an isolated radiating black hole cannot have an emission spectrum that is precisely thermal. Moreover, the no-hair theorem is only approxima…
Decoupling in an expanding universe: boundary RG-flow affects initial conditions for inflation
Koenraad Schalm, Gary Shiu, Jan Pieter van der Schaar
We study decoupling in FRW spacetimes, emphasizing a Lagrangian description throughout. To account for the vacuum choice ambiguity in cosmological settings, we introduce an arbitra…
