准精确可解量子晶格孤子

Quasi exactly solvable quantum lattice solitons

Y. Brihaye, N. Debergh, A. Nininahazwe

摘要:

本文利用一种新的相互作用推广了J.Dorignac等人最近研究的描述$f$量子振子的精确可解哈密顿量,并选择这种相互作用作为准精确可解的相互作用.研究了这种新的哈密顿量的谱的性质作为新的耦合常数的函数。这个哈密顿量和原来的哈密顿量也与适当的李结构有关。

英文摘要:

We extend the exactly solvable Hamiltonian describing $f$ quantum oscillators considered recently by J. Dorignac et al. by means of a new interaction which we choose as quasi exactly solvable. The properties of the spectrum of this new Hamiltonian are studied as function of the new coupling constant. This Hamiltonian as well as the original one are also related to adequate Lie structures.
