Fermion Condensate Inflation, Dynamical Waterfall Mechanism and Primordial Black Holes
Stephon Alexander, Pisin Chen, Jinglong Liu +3
Fermion condensate inflation, where inflation emerges from four-fermion interactions induced by spacetime torsion, removes the need for additional scalar fields beyond the Standard…

Hybrid Inflation from Fermion Condensate
Stephon Alexander, Pisin Chen, Jinglong Liu +3
We investigate how inflation can emerge from four-fermion interactions generated by spacetime torsion, eliminating the need for additional scalar fields beyond the Standard Model.…

Birefringence in fermion-attenuated gravitational wave power spectrum
Jinglong Liu, Stephon Alexander, Antonino Marciano
Within the framework of Chern-Simons gravity, a theory that dynamically violates parity, we analyze the power spectrum of gravitational waves in light of the damping effect due to…
