立方晶格的本征局域模及孤立子

THE INTRINSIC LOCALIZED MODE AND THE SOLITON OF CUBIC LATTICE

本文通过求解具有最邻近相互作用的一维立方晶格,发现了除声学模和光学模外,还存在本征局域模,并用相干态方法求出了立方晶格的孤立子解及能量等。

The one dimensional cubic lattice with nearest neighbor interactionis investigated. It is shown that such an intrinsic localized mode can appear at any lattice site except optic mode and acoustic mode. The soliton solution of the cubic lattice is obtained with coherent state method.
