Minimal time for the bilinear control of Schrödinger equations
We consider a quantum particle in a potential V (x) (x ∈ R ) subject to a (spatially homogeneous) time-dependent electric field E(t), which plays the role of the control. Under generic assumptions on V , this system is approximately controllable on the L(R ,C)-sphere, in sufficiently large times T , as proved by Boscain, Caponigro, Chambrion and Sigalotti [7]. In the present article, we show th...
متن کاملglobal results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Some Local Wellposedness Results for Nonlinear Schrödinger Equations below L
In this paper we prove some local (in time) wellposedness results for non-linear Schrödinger equations ut − i∆u = N (u, u), u(0) = u0 with rough data, that is, the initial value u0 belongs to some Sobolev space of negative index. We obtain positive results for the following nonlinearities and data:
متن کاملA minimal energy tracking method for non-radially symmetric solutions of coupled nonlinear Schrödinger equations
We aim at developing methods to track minimal energy solutions of time-independent mcomponent coupled discrete nonlinear Schrödinger (DNLS) equations. We first propose a method to find energy minimizers of the 1-component DNLS equation and use it as the initial point of the m-component DNLS equations in a continuation scheme. We then show that the change of local optimality occurs only at the b...
متن کاملOf Nonlinear Schrödinger Equations
The authors suggest a new powerful tool for solving group classification problems, that is applied to obtaining the complete group classification in the class of nonlinear Schrödinger equations of the form iψt +∆ψ + F (ψ,ψ ∗) = 0.
