Bipartite entanglement of the primordial Majorana during inflation
Ai-chen Li, Han-Qing Shi, Keyun Wu
We use a primordial Majorana field as a fermionic probe of quantum correlations during inflation. Working in a torsion-free FLRW spacetime, we derive the two-component Majorana mod…
Torsion induced one-loop corrections to inflaton decay and the Stochastic gravitational waves
AlexKen Lee, Keyun Wu
We investigate one-loop corrections from torsion-induced four-fermion interactions to inflaton three-body decay and their impact on the associated stochastic gravitational-wave sig…
Enhanced Stochastic Gravitational Waves signals from Wess-Zumino chiral superfield
AlexKen Lee, Keyun Wu
In this work, we investigate the possibility that supersymmetric structures may leave observable imprints in the stochastic gravitational-wave (GW) background generated during the…
Dirac neutrino and dark matter in left-right symmetric models
Shohei Okawa, Yuji Omura, Keyun Wu
We study neutrino mass generation and dark matter in a left-right symmetric model. The model is based on an gauge theory wi…
