Soliton dynamics in a potential

Research output: Contribution to journalArticlepeer-review


We study the semiclassical limit of subcritical focussing NLS with a potential, for initial data of the form s(cursive Greek chi-cursive Greek chi0/∈)ei v0-cursive Greek chi/∈, where s is the ground state of an associated unscaled problem. We show that in the semiclassical limit, the solution has roughly the form s(cursive Greek chi-cursive Greek chi∈(t)/∈)ei v∈(t)-cursive Greek chi/∈, and we show that the approximate center of mass cursive Greek chi(·) converges to a solution of the equation cursive Greek chi″ = -DV(cursive Greek chi), cursive Greek chi(0) = cursive Greek chi0, cursive Greek chi′(0) = v0 as ∈ → 0.
