Derivation of the cubic non-linear Schrödinger equation from quantum dynamics of many-body systems

- L. Erdős, B. Schlein, H. Yau
- Mathematics, Physics
- 2 August 2005

We prove rigorously that the one-particle density matrix of three dimensional interacting Bose systems with a short-scale repulsive pair interaction converges to the solution of the cubic non-linear… Expand

Derivation of the Gross-Pitaevskii equation for the dynamics of Bose-Einstein condensate

Consider a system of N bosons in three dimensions interacting via a repulsive short range pair potential N 2 V (N(xi − xj)), where x = (x1, . . ., xN) denotes the positions of the particles. Let HN… Expand

Derivation of the Gross‐Pitaevskii hierarchy for the dynamics of Bose‐Einstein condensate

- Mathematics
- 2 October 2004

Consider a system of N bosons on the three‐dimensional unit torus interacting via a pair potential N2V(N(xi − xj)) where x = (x1, …, xN) denotes the positions of the particles. Suppose that the… Expand

The Chandrasekhar theory of stellar collapse as the limit of quantum mechanics

Starting with a “relativistic” Schrödinger Hamiltonian for neutral gravitating particles, we prove that as the particle numberN→∞ and the gravitation constantG→0 we obtain the well known… Expand

- L. Erdős, B. Schlein, H. Yau
- Mathematics
- 26 February 2008

Consider a system of $N$ bosons in three dimensions interacting via a repulsive short range pair potential $N^2V(N(x_i-x_j))$, where $\bx=(x_1, >..., x_N)$ denotes the positions of the particles. Let… Expand

Spectral statistics of Erdős–Rényi graphs I: Local semicircle law

- L'aszl'o ErdHos, A. Knowles, H. Yau, Jun Yin
- Mathematics
- 9 March 2011

We consider the ensemble of adjacency matrices of Erdős–Renyi random graphs, that is, graphs on N vertices where every edge is chosen independently and with probability p≡p(N). We rescale the matrix… Expand

The local semicircle law for a general class of random matrices

- L. Erdős, A. Knowles, H. Yau, Jun Yin
- Mathematics
- 1 December 2012

We consider a general class of $N\times N$ random matrices whose entries $h_{ij}$ are independent up to a symmetry constraint, but not necessarily identically distributed. Our main result is a local… Expand

Bulk universality for generalized Wigner matrices

Consider N × N Hermitian or symmetric random matrices H where the distribution of the (i, j) matrix element is given by a probability measure νij with a subexponential decay. Let $${\sigma_{ij}^2}$$… Expand

Derivation of the nonlinear Schr\"odinger equation from a many body Coulomb system

We consider the time evolution of N bosonic particles interacting via a mean field Coulomb potential. Suppose the initial state is a product wavefunction. We show that at any finite time the… Expand
