X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…

Generalization of a localized-state formation mechanism in finite lattices with interaction nonlinearity
Huajie Song, Haitao Xu
We study how time-periodic, spatially localized states are born from the linear spectrum of a \emph{finite} lattice as the nonlinearity is switched on. In earlier work we treated t…
