Constrained energy minimization and orbital stability for the NLS equation on a star graph
R. Adami, C. Cacciapuoti, D. Finco +1
We consider a nonlinear Schrödinger equation with focusing nonlinearity of power type on a star graph , written as , wh…
Variational properties and orbital stability of standing waves for NLS equation on a star graph
R. Adami, C. Cacciapuoti, D. Finco +1
We study standing waves for a nonlinear Schrödinger equation on a star graph {} i.e. half-lines joined at a vertex. At the vertex an interaction occurs described b…
On the structure of critical energy levels for the cubic focusing NLS on star graphs
Riccardo Adami, Claudio Cacciapuoti, Domenico Finco +1
We provide information on a non trivial structure of phase space of the cubic NLS on a three-edge star graph. We prove that, contrarily to the case of the standard NLS on the line,…
Stability for a System of N Fermions Plus a Different Particle with Zero-Range Interactions
M. Correggi, G. Dell'Antonio, D. Finco +2
We study the stability problem for a non-relativistic quantum system in dimension three composed by identical fermions, with unit mass, interacting with a different pa…
