Extended Cuscuton as Dark Energy
Aya Iyonaga, Kazufumi Takahashi, Tsutomu Kobayashi
Late-time cosmology in the extended cuscuton theory is studied, in which gravity is modified while one still has no extra dynamical degrees of freedom other than two tensor modes.…
Dressed Power-law Inflation with Cuscuton
Asuka Ito, Aya Iyonaga, Suro Kim +1
We study dressed inflation with a cuscuton and find a novel exact power-law solution. It is well known that the conventional power-law inflation is inconsistent with the Planck dat…
Extended Cuscuton: Formulation
Aya Iyonaga, Kazufumi Takahashi, Tsutomu Kobayashi
Among single-field scalar-tensor theories, there is a special class called "cuscuton," which is represented as some limiting case of k-essence in general relativity. This theory ha…
