Abstract
n this work we consider the magnetic NLS equation (ℏ/i∇ - A (x))2 u+V (x)u -f (|u|2)u = o in ℝN where N ≥ 3, A: ℝN → ℝ is a magnetic potential, possibly unbounded, V:ℝN → ℝ is a multi-well electric potential, which can vanish somewhere, f is a subcritical nonlinear term. We prove the existence of a semiclassical multi-peak solution u:ℝN → C to (0.1), under conditions on the nonlinearity which are nearly optimal.File in questo prodotto:
