Vlasov simulation of Langmuir wave packets
... A possible mechanism for the formation of small- amplitude Langmuir wave packets is the “kinetic localiza- tion” (Muschietti et al., 1995, 1996), in which Langmuir waves are modulated in space due to ...

Signatures of chaos and non-integrability in two-dimensional gravity with dynamical boundary
... Abstract. We propose a model of two-dimensional dilaton gravity with a boundary. In the bulk our model coincides with the classically integrable CGHS model; the dynamical boundary cuts off the CGHS strong-coupling region. ...
