Screening of scalar fields in Dirac-Born-Infeld theory (2014)
Journal Article
Burrage, C., & Khoury, J. (2014). Screening of scalar fields in Dirac-Born-Infeld theory. Physical Review D, D90(2), Article 024001. https://doi.org/10.1103/PhysRevD.90.024001

We study a new screening mechanism which is present in Dirac-Born-Infeld (DBI)-like theories. A scalar field with a DBI-like Lagrangian is minimally coupled to matter. In the vicinity of sufficiently dense sources, nonlinearities in the scalar domina... Read More about Screening of scalar fields in Dirac-Born-Infeld theory.

Chameleons in the early universe: kicks, rebounds, and particle production (2014)
Journal Article
Erickcek, A. L., Barnaby, N., Burrage, C., & Huang, Z. (2014). Chameleons in the early universe: kicks, rebounds, and particle production. Physical Review D, D89(8), Article 084074. https://doi.org/10.1103/PhysRevD.89.084074

Chameleon gravity is a scalar-tensor theory that includes a nonminimal coupling between the scalar field and the matter fields and yet mimics general relativity in the Solar System. The scalar degree of freedom is hidden in high-density environments... Read More about Chameleons in the early universe: kicks, rebounds, and particle production.
