Stochastic Baryogenesis
Yi-Peng Wu, Kalliopi Petraki
Using a multi-field stochastic approach, we investigate the vacuum expectation value (VEV) during inflation of a scalar field charged under a mildly broken global symmetry t…
Peak statistics for the primordial black hole abundance
Yi-Peng Wu
The primordial black hole (PBH) abundance evaluated by the conventional Press-Schechter (PS) probability distribution is shown to be equivalent to the high-peak limit of a special…
Leptogenesis from spontaneous symmetry breaking during inflation
Yi-Peng Wu, Louis Yang, Alexander Kusenko
Symmetry breaking in the Higgs field via a non-minimal coupling to gravity or higher-dimensional interactions with the inflaton can lead to condensation at a large vacuum expectati…
Higgs as heavy-lifted physics during inflation
Yi-Peng Wu
Signals of heavy particle production during inflation are encoded as non-analytic momentum scaling in primordial non-Gaussianity. These non-analytic signatures can be sourced by St…
Hybrid Quasi-Single Field Inflation
Yi Wang, Yi-Peng Wu, Jun'ichi Yokoyama +1
The decay of massive particles during inflation generates characteristic signals in the squeezed limit of the primordial bispectrum. These signals are in particular distinctive in…
Role of spacetime boundaries in Einstein's other gravity
Naritaka Oshita, Yi-Peng Wu
Einstein's vierbein formulation of general relativity based on the notion of distant parallelism (teleparallelism) naturally introduces a covariant surface term in addition to the…
