Anisotropic constant-roll inflation for the Dirac-Born-Infeld model
Duy H. Nguyen, Tuyen M. Pham, Tuan Q. Do
In this paper, we study a non-canonical extension of a supergravity-motivated model acting as a vivid counterexample to the cosmic no-hair conjecture due to its unusual coupling be…
Anisotropic power-law inflation for a model of two scalar and two vector fields
Tuan Q. Do, W. F. Kao
Inspired by an interesting counterexample to the cosmic no-hair conjecture found in a supergravity-motivated model recently, we propose a multi-field extension, in which two scalar…
Stable small spatial hairs in a power-law k-inflation model
Tuan Q. Do
In this paper, we extend our investigation of the validity of the cosmic no-hair conjecture within non-canonical anisotropic inflation. As a result, we are able to figure out an ex…
No small hairs in anisotropic power-law Gauss-Bonnet inflation
Tuan Q. Do, Sonnet Hung Q. Nguyen
We will examine whether anisotropic hairs exist in a string-inspired scalar-Gauss-Bonnet gravity model with the absence of potential of scalar field during the inflationary phase.…
On the validity of cosmic no-hair conjecture in an anisotropic inflationary model
Tuan Q. Do
We will present main results of our recent investigations on the validity of cosmic no-hair conjecture proposed by Hawking and his colleagues long time ago in the framework of an a…
Anisotropic power-law inflation in a two-scalar-field model with a mixed kinetic term
Tuan Q. Do, Sonnet Hung Q. Nguyen
We examine whether an extended scenario of a two-scalar-field model, in which a mixed kinetic term of canonical and phantom scalar fields is involved, admits the Bianchi type I met…
