Exploring Answers to Questions
Jonathan J. Heckman, Austin Joyce, Jeremy Sakstein +1
We explore potential uses of physics formulated in Kleinian (i.e., ) signature spacetimes as a tool for understanding properties of physics in Lorentzian (i.e., ) signatu…
Pixelated Dark Energy
Jonathan J. Heckman, Craig Lawrie, Ling Lin +2
We study the phenomenology of a recent string construction with a quantum mechanically stable dark energy. A mild supersymmetry protects the vacuum energy but also allows $O(10 - 1…
Oscillons in Higher-Derivative Effective Field Theories
Jeremy Sakstein, Mark Trodden
We investigate the existence and behavior of oscillons in theories in which higher derivative terms are present in the Lagrangian, such as galileons. Such theories have emerged in…
Superfluids and the Cosmological Constant Problem
Justin Khoury, Jeremy Sakstein, Adam R. Solomon
We introduce a novel method to circumvent Weinberg's no-go theorem for self-tuning the cosmological vacuum energy: a Lorentz-violating finite-temperature superfluid can counter the…
SUPER-Screening
Philippe Brax, Anne-Christine Davis, Jeremy Sakstein
We present a framework for embedding scalar-tensor models of screened modifed gravity such as chameleons, symmetrons and environmental dilatons into global supersymmetry. This achi…
