The O(dd) story of massive supergravity
- N. Kaloper, R. Myers
- Physics
- 12 January 1999
The low energy effective action describing the standard Kaluza-Klein reduction of heterotic string theory on a d-torus possesses a manifest O(d,d+16) symmetry. We consider generalized Scherk-Schwarz… Expand
String Axiverse
- A. Arvanitaki, S. Dimopoulos, S. Dubovsky, N. Kaloper, J. March-Russell
- Physics
- 28 May 2009
String theory suggests the simultaneous presence of many ultralight axions, possibly populating each decade of mass down to the Hubble scale 10−33eV. Conversely the presence of such a plenitude of… Expand
A Small cosmological constant from a large extra dimension
- N. Arkani-Hamed, S. Dimopoulos, N. Kaloper, R. Sundrum
- Physics
- 31 January 2000
We propose a new approach to the Cosmological Constant Problem which makes essential use of an extra dimension. A model is presented in which the Standard Model vacuum energy “warps” the… Expand
Duality beyond the first loop
- N. Kaloper, K. Meissner
- Physics
- 25 May 1997
In this article we give a calculation of the two-loop {sigma}-model corrections to the T-duality map in string theory. We use the effective action approach, and analyze two-loop corrections in a… Expand
A natural framework for chaotic inflation.
- N. Kaloper, L. Sorbo
- Physics, Medicine
- Physical review letters
- 12 November 2008
We show that inflation with a quadratic potential occurs naturally in theories where an axionlike field mixes with a 4-form. Such an axion is massive, with the mass which arises from the mixing being… Expand
Signatures of short distance physics in the cosmic microwave background
- N. Kaloper, M. Kleban, A. Lawrence, S. Shenker
- Physics
- 21 January 2002
We systematically investigate the effect of short distance physics on the spectrum of temperature anistropies in the Cosmic Microwave Background produced during inflation. We present a general… Expand
Bent domain walls as brane worlds
- N. Kaloper
- Physics
- 27 May 1999
We consider domain walls embedded in curved backgrounds as an approximation for braneworld scenarios. We give a large class of new exact solutions, exhausting the possibilities for describing one and… Expand
An ignoble approach to large field inflation
- N. Kaloper, A. Lawrence, L. Sorbo
- Physics
- 30 December 2010
We study an inflationary model developed by Kaloper and Sorbo, in which the inflaton is an axion with a sub-Planckian decay constant, whose potential is generated by mixing with a topological 4-form… Expand
Quantum Black Holes as Holograms in AdS Braneworlds
- R. Emparan, A. Fabbri, N. Kaloper
- Physics
- 18 June 2002
We propose a new approach for using the AdS/CFT correspondence to study quantum black hole physics. The black holes on a brane in an AdSD+1 braneworld that solve the classical bulk equations are… Expand
String theory and quintessence
- S. Hellerman, N. Kaloper, L. Susskind
- Physics
- 23 April 2001
We discuss the obstacles for defining a set of observable quantities analogous to an S-matrix which are needed to formulate string theory in an accelerating universe. We show that the quintessence… Expand
