A. L. Lisok, A. Yu. Trifonov, A. V. Shapovalov

摘要:

基于Maslov复芽理论的思想,给出了一类具有二次位势的Hartree型方程在半经典集中函数类中Cauchy问题的精确解的一种求解方法.在半经典集中函数类中得到了非线性演化算子的显式表达式。Hartree型方程的对称算子的参数族已经被发现。借助于对称算子,构造了方程的精确解族。精确的表达式获得的准能量和它们各自的状态。Aharonov-Anandan几何相位被发现在明确的形式的准能态。

英文摘要:

Based on the ideology of the Maslov's complex germ theory, a method has been developed for finding an exact solution of the Cauchy problem for a Hartree-type equation with a quadratic potential in the class of semiclassically concentrated functions. The nonlinear evolution operator has been obtained in explicit form in the class of semiclassically concentrated functions. Parametric families of symmetry operators have been found for the Hartree-type equation. With the help of symmetry operators, families of exact solutions of the equation have been constructed. Exact expressions are obtained for the quasi-energies and their respective states. The Aharonov-Anandan geometric phases are found in explicit form for the quasi-energy states.
