modular inflation
Si-Yi Jiang, Wenbin Zhao, Gui-Jun Ding
We investigate inflation models governed by the Siegel modular group . The group extends the framework from one modulus to t…
Modular invariant inflation and reheating
Gui-Jun Ding, Si-Yi Jiang, Yong Xu +1
We use modular symmetry as an organizing principle that attempts to simultaneously address the lepton flavor puzzle, inflation, and post-inflationary reheating. We demonstrate this…
Modular Invariant Slow Roll Inflation
Gui-Jun Ding, Si-Yi Jiang, Wenbin Zhao
We propose new classes of inflation models based on the modular symmetry, where the modulus field serves as the inflaton. We establish a connection between modular inflation an…
Pati-Salam models with modular symmetry
Gui-Jun Ding, Si-Yi Jiang, Stephen F. King +2
The flavor structure of quarks and leptons and quark-lepton unification are studied in the framework of Pati-Salam models with modular symmetry. The three generations of the…
