k-inflation: Non-separable case meets ACT measurements
Tahere Fallahi Serish, Seyed Ali Hosseini Mansoori, Fereshteh Felegary +2
We investigate a non-separable subset of -essence in which the kinetic and potential sectors interact through an coupling, implemented via a potential-dependent pref…

Neutrino spin oscillations in gravitational fields in noncommutative higher dimensions
S. A. Alavi, T. Fallahi Serish
Investigation of neutrino spin oscillation in the gravitational fields of black holes (BHs) is one of the interesting topics in neutrino physics. On the other hand, in recent years…

Tilt and Tensor-to-Scalar Ratio in Multi-Scalar Field Inflation: Non-Sum-Separable Case
Fereshteh Felegary, Seyed Ali Hosseini Mansoori, Tahere Fallahi Serish +1
The canonical multi-scalar field inflation where the kinetic and potential terms are sum-separable is ruled out by the current observations for the chaotic-type potential $V=\sum_{…
