自旋1/2铁磁模型的相互作用淬灭
Spin-1/2 heisenberg ferromagnetic model following an interaction quench
摘要
Abstract
Spin-1/2 Heisenberg ferromagnetic model is considered as the original object of discussion. The spin-spin correlation of the model after a suddenly switch-on interaction is analytically studied. By solving the Heisenberg equation, the analytical form of spin operator is obtained in the limit of low temperature. The spin propagator is discussed mainly. The differences of energy spectrums are found and discussed.关键词
