Inflation in string theory confronts data/Les modèles d'inflation en théorie des cordes face aux observations
Eva Silverstein
Following the 2015 Planck release, we briefly comment on the status and some ongoing opportunities in the interface between inflationary cosmology, string theory, and CMB data. The…
Tensor Networks from Kinematic Space
Bartlomiej Czech, Lampros Lamprou, Samuel McCandlish +1
We point out that the MERA network for the ground state of a 1+1-dimensional conformal field theory has the same structural features as kinematic space---the geometry of CFT interv…
Inflatino-less Cosmology
John Joseph M. Carrasco, Renata Kallosh, Andrei Linde
We construct inflationary models in the context of supergravity with orthogonal nilpotent superfields [1]. When local supersymmetry is gauge-fixed in the unitary gauge, these model…
The Two-Loop Symbol of all Multi-Regge Regions
Till Bargheer, Georgios Papathanasiou, Volker Schomerus
We study the symbol of the two-loop n-gluon MHV amplitude for all Mandelstam regions in multi-Regge kinematics in N=4 super Yang-Mills theory. While the number of distinct Mandelst…
Schwinger pair production at nonzero temperatures or in compact directions
Adam R. Brown
Electric fields may decay by quantum tunneling: as calculated by Schwinger, an electron-positron pair may be summoned from the vacuum. In this paper I calculate the pair-production…
Complexity, action, and black holes
Adam R. Brown, Daniel A. Roberts, Leonard Susskind +2
Our earlier paper "Complexity Equals Action" conjectured that the quantum computational complexity of a holographic state is given by the classical action of a region in the bulk (…
