Description:
Author(s): Tianjun Li, Zhijin Li, and 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 supergravity. The global U(1) symmetry of the Kähler potential introduces a flat direction and evades the η problem auto...
