Kinetic equation for Lifshitz scalar
Shinji Mukohyama, Yota Watanabe
Employing the method of Wigner functions on curved spaces, we study classical kinetic (Boltzmann-like) equations of distribution functions for a real scalar field with the Lifshitz…

Is the DBI scalar field as fragile as other -essence fields?
Shinji Mukohyama, Ryo Namba, Yota Watanabe
Caustic singularity formations in shift-symmetric -essence and Horndeski theories on a fixed Minkowski spacetime were recently argued. In dimensions, this singularity is the…

Hamiltonian analysis of nonprojectable Hořava-Lifshitz gravity with symmetry
Shinji Mukohyama, Ryo Namba, Rio Saitou +1
We study the nature of constraints and count the number of degrees of freedom in the nonprojectable version of the extension of Hořava-Lifshitz gravity, using the standard m…
