Helical Phase Inflation and Monodromy in Supergravity Theory
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We study helical phase inflation in supergravity theory in details. The inflation is driven by the phase component of a complex field along helical trajectory. The helicoid structu…
Helical Phase Inflation
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We show that the quadratic inflation can be realized by the phase of a complex field with helicoid potential. Remarkably, this helicoid potential can be simply realized in minimal…
Aligned Natural Inflation and Moduli Stabilization from Anomalous Gauge Symmetries
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
To obtain natural inflation with large tensor-to-scalar ratio in string framework, we need a special moduli stabilization mechanism which can separate the masses of real and imagin…
Natural Inflation with Natural Trans-Planckian Axion Decay Constant from Anomalous
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
We propose a natural inflation model driven by an imaginary or axionic component of a Kähler modulus in string-inspired supergravity. The shift symmetry of the axion is gauged unde…
Chaotic Inflation in No-Scale Supergravity with String Inspired Moduli Stabilization
Tianjun Li, Zhijin Li, Dimitri V. Nanopoulos
The simple chaotic inflation is highly consistent with the BICEP2 experiment, and no-scale supergravity can be realized naturally in various string compactifications. Thus, we cons…
