Non-Fierz-Pauli bimetric theory from quadratic curvature gravity on Einstein manifolds

Yuki Niiyama, Yuya Nakamura, Ryosuke Zaimokuya +2

We show that, in four-dimensional spacetimes with an arbitrary Einstein metric, with and without a cosmological constant, perturbative dynamical degrees of freedom in generic quadr…

A quantisation procedure in the presence of an initial Kasner singularity: primordial gravitational waves from triaxially anisotropic pre-inflation

Yu Furuya, Yuki Niiyama, Yuuiti Sendouda

In this paper, we discuss quantisation of cosmological tensor perturbations in the Kasner-de Sitter space-time as a model of (pre-)inflation. Quantisation in such an anisotropic ba…
