The Gross-pitaevskii Hierarchy on General Rectangular Tori
نویسنده
چکیده
In this work, we study the Gross-Pitaevskii hierarchy on general –rational and irrational– rectangular tori of dimension two and three. This is a system of infinitely many linear partial differential equations which arises in the rigorous derivation of the nonlinear Schrödinger equation. We prove a conditional uniqueness result for the hierarchy. In two dimensions, this result allows us to obtain a rigorous derivation of the defocusing cubic nonlinear Schrödinger equation from the dynamics of many-body quantum systems. On irrational tori, this question was posed as an open problem in previous work of Kirkpatrick, Schlein, and Staffilani.

A Short Proof of Local Well-posedness for Focusing and Defocusing Gross-pitaevskii Hierarchies
We consider the cubic and quintic Gross-Pitaevskii (GP) hierarchy in d dimensions, for focusing and defocusing interactions. We give a new proof of local well-posedness which avoids any high order Duhamel expansions, in contrast to previous proofs. Instead, we establish a new Strichartz estimate on the free evolution for GP hierarchies, and develop a T −T ∗ type argument, which, in turn, makes ...
متن کاملDerivation of the Gross-Pitaevskii Hierarchy for the Dynamics of Bose-Einstein Condensate
Consider a system of N bosons on the three dimensional unit torus interacting via a pair potentialNV (N(xi−xj)), where x = (x1, . . . , xN ) denotes the positions of the particles. Suppose that the initial data ψN,0 satisfies the condition 〈ψN,0, H NψN,0〉 ≤ CN where HN is the Hamiltonian of the Bose system. This condition is satisfied if ψN,0 = WNφN,0 where WN is an approximate ground state to ...
متن کاملOn the Cauchy Problem for Focusing and Defocusing Gross-pitaevskii Hierarchies
We consider the dynamical Gross-Pitaevskii (GP) hierarchy on Rd, d ≥ 1, for cubic, quintic, focusing and defocusing interactions. For both the focusing and defocusing case, and any d ≥ 1, we prove local wellposedness of the Cauchy problem in weighted Sobolev spacesHα ξ of sequences of marginal density matrices, for α ><>: > 1 2 if d = 1 > d 2 − 1 2(p−1) if d ≥ 2 and (d, p) 6= (3, 2) ≥ 1 if (d, ...
متن کاملMultilinear Morawetz Identities for the Gross-pitaevskii Hierarchy
This article consists of two parts. In the first part, we review the most recent proofs establishing quadratic Morawetz inequalities for the nonlinear Schrödinger equation (NLS). We also describe the applications of these estimates to the problem of quantum scattering. In the second part, we generalize some of the methods developed for the NLS by many authors to the case of Gross-Pitaevskii (GP...
متن کاملGross-Pitaevskii Equation as the Mean Field Limit of Weakly Coupled Bosons
We consider the dynamics of N boson systems interacting through a pair potential N−1Va(xi− xj) where Va(x) = a V (x/a). We denote the solution to the N -particle Schrödinger equation by ψN,t. Recall that the Gross-Pitaevskii (GP) equation is a nonlinear Schrödinger equation and the GP hierarchy is an infinite BBGKY hierarchy of equations so that if ut solves the GP equation, then the family of ...
