Sequestering effects on and of vacuum decay (2016)
Journal Article
Kaloper, N., Padilla, A., & Stefanyszyn, D. (2016). Sequestering effects on and of vacuum decay. Physical Review D, 94(2), Article 25022. https://doi.org/10.1103/PhysRevD.94.025022

We consider phase transitions and their contributions to vacuum energy in the manifestly local theory of vacuum energy sequestering. We demonstrate that the absence of instabilities imposes constraints on the couplings of gravitating and nongravitati... Read More about Sequestering effects on and of vacuum decay.

How to avoid a swift kick in the chameleons (2016)
Journal Article
Padilla, A., Platts, E., Stefanyszyn, D., Walters, A., Weltman, A., & Wilson, T. (2016). How to avoid a swift kick in the chameleons. Journal of Cosmology and Astroparticle Physics, 2016, Article 58. https://doi.org/10.1088/1475-7516/2016/03/058

Recently, it was argued that the conformal coupling of the chameleon to matter fields created an issue for early universe cosmology. As standard model degrees of freedom become non-relativistic in the early universe, the chameleon is attracted toward... Read More about How to avoid a swift kick in the chameleons.

Manifestly Local Theory of Vacuum Energy Sequestering (2016)
Journal Article
Kaloper, N., Padilla, A., Stefanyszyn, D., & Zahariade, G. (2016). Manifestly Local Theory of Vacuum Energy Sequestering. Physical Review Letters, 116(5), Article 051302. https://doi.org/10.1103/PhysRevLett.116.051302

© 2016 American Physical Society. We present a manifestly local, diffeomorphism invariant, and locally Poincaré invariant formulation of vacuum energy sequestering. In this theory, quantum vacuum energy generated by matter loops is canceled by auxili... Read More about Manifestly Local Theory of Vacuum Energy Sequestering.
