Open-channel radiation zeros and nonlinear damping of a critical-bubble internal mode
Tomohiro Inagaki, Yuko Murakami
We study radiation and nonlinear damping of a spherically symmetric localized mode of an thermal critical bubble. The leading second-harmonic radiation amplitude is determin…

Localized scalar modes of critical bubbles: partial-wave continuum mergers and wave-function deformation
Tomohiro Inagaki, Yuko Murakami
At phase coexistence, a degenerate quartic scalar potential admits an exact planar kink whose normal fluctuation operator is the modified Pöschl--Teller operator, with translationa…
