Power-law Bianchi type I inflation with multiple vector fields
Duy H. Nguyen, Tuan Q. Do
We investigate an inflationary anisotropic universe in a supergravity-motivated model with one scalar field non-minimally coupled to multiple vector fields. We restrict ourselves t…
Anisotropic power-law inflation for the Sáez-Ballester theory non-minimally coupled to a vector field
Tuan Q. Do, Phung V. Dong, Duy H. Nguyen +1
In this paper, we would like to examine whether the Sáez-Ballester theory admits stable and attractive Bianchi type I inflationary solutions in the presence of a non-minimal coupli…
Stability investigations of de Sitter inflationary solutions in power-law extensions of the Starobinsky model
Tuyen M. Pham, Duy H. Nguyen, Tuan Q. Do +1
In this paper, we would like to examine whether stable de Sitter inflationary solutions appear within power-law extensions of the Starobinsky model. In particular, we will address…
Anisotropic power-law inflation for models of non-canonical scalar fields non-minimally coupled to a two-form field
Tuyen M. Pham, Duy H. Nguyen, Tuan Q. Do +1
In this paper, we investigate the validity of the so-called cosmic no-hair conjecture in the framework of anisotropic inflation models of non-canonical scalar fields non-minimally…
Stability investigations of isotropic and anisotropic exponential inflation in the Starobinsky-Bel-Robinson gravity
Tuan Q. Do, Duy H. Nguyen, Tuyen M. Pham
In this paper, we would like to examine whether a novel Starobinsky-Bel-Robinson gravity model admits stable exponential inflationary solutions with or without spatial anisotropies…
Superconductivity in an extreme strange metal
D. H. Nguyen, A. Sidorenko, M. Taupin +4
Some of the highest-transition-temperature superconductors across various materials classes exhibit linear-in-temperature `strange metal' or `Planckian' electrical resistivities in…
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…
k-Gauss-Bonnet inflation
Tuyen M. Pham, Duy H. Nguyen, Tuan Q. Do
We propose a novel {\it k}-Gauss-Bonnet inflationary model, in which a kinetic term of scalar field is allowed to non-minimally couple to the Gauss-Bonnet topological invariant in…
