Spinon excitation spectra of the - chain from analytical calculations in the dimer basis and exact diagonalization
Arthur Lavarélo, Guillaume Roux
The excitation spectrum of the frustrated spin- Heisenberg chain is reexamined using variational and exact diagonalization calculations. We show that the overlap matrix of the…

Localization of spinons in random Majumdar-Ghosh chains
Arthur Lavarélo, Guillaume Roux
We study the effect of disorder on frustrated dimerized spin-1/2 chains at the Majumdar-Ghosh point. Using variational methods and density-matrix renormalization group approaches,…
