We discuss how to create multipartite entanglement. By coupling a new particle with entangled particles via Heisenberg interaction between two particles, we can
The approximate generalized conditional symmetry (AGCS) approach we previously proposed [Chin. Phys. Lett. 23 (2006) 527] is applied to study the perturbed gene
For a nonholonomic mechanics system with the action of small disturbance, the Lie symmetrical perturbation and adiabatic invariants of generalized Hojman type a
A simple symmetry reduction procedure is repeatedly used to obtain infinitely many symmetries and then the exact solutions of the Burgers equation. Some sets of
The exact periodic homoclinic wave of (1+1) D long-short wave equation is obtained using an extended homoclinic test technique.This result shows complexity and
Applying the Fourier pseudospectral method to space derivatives and the symplectic Euler rule to time derivatives in the multisymplectic form of the Klein-Gordo
The surface in R3 associated with the Tzitzeica equation is considered. By curvature coordinate transformation and surface imbedding, the Gauss-Codazzi equation
Two (2+1)-dimensional (3D) lattice systems are proposed in view of the compatibility of 2D lattice systems in the same hierarchy. Furthermore, the Darboux trans
We consider three two-level atoms (A, B, and C) initially in the W entanglement state, then one of them, C, is injected into a high-Q cavity to make resonant in
