Title: Discussions on New and Old Mechanisms of Leptogenesis

Abstract: In the first half of the talk, I will present preliminary
results which indicate the scale of thermal leptogenesis may be
several orders of magnitude lower than previously thought. In the
second half of this talk, I will present a mechanism of leptogenesis
which is based on the vacuum CP-violating phase transition. This
approach differs from classical thermal leptogenesis as a specific
seesaw model, and its UV completion, need not be specified. The lepton
asymmetry is generated via the dynamically realized coupling of the
Weinberg operator during the phase transition. This mechanism provides
strong connections with low-energy neutrino experiments.
