摘要: The complete spectrum of the double spinon excitation in spin-Peierls system CuGe${\mathrm{O}}_{3}$ is mapped as a function temperature for first time. spin dynamics lower boundary and continuum evolve quite differently. Moreover, dimerization lattice produces sharp energy at edge Brillouin zone, well known spin-gap opening zone center.
