Investigation of soliton bound states in the Raman spectrum of pure and doped spin-Peierls chains
D. Augier, E. Sorensen, J. Riera +1
We investigate the occurrence of singlet bound states in the Raman spectrum of dimerized spin 1/2 chains by Exact Diagonalization and Density Matrix Renormalization Group technique…
Interaction between impurities and solitons in quasi one-dimensional spin-Peierls systems
D. Augier, P. Hansen, D. Poilblanc +2
The role of the spin-phonon coupling in spin-Peierls chains doped with spin-0 or spin-1 impurities is investigated by various numerical methods such as exact diagonalization, quant…
Soliton Approach to Spin-Peierls Antiferromagnets: Large-Scale Numerical Results
E. Sorensen, I. Affleck, D. Augier +1
A simple intuitive picture of spin-Peierls antiferromagnets arises from regarding the elementary excitations as S=1/2 solitons. In a strictly one-dimensional system these excitatio…
Study of impurities in spin-Peierls systems including lattice relaxation
P. Hansen, D. Augier, J. Riera +1
The effects of magnetic and non-magnetic impurities in spin-Peierls systems are investigated allowing for lattice relaxation and quantum fluctuations. We show that, in isolated cha…
Dynamical effects of phonons on soliton binding in spin-Peierls systems
D. Augier, D. Poilblanc, E. Sorensen +1
The role of dynamical magneto-elastic coupling in spin-Peierls chains is investigated by numerical and analytical techniques. We show that a Heisenberg spin chain coupled to dynami…
Study of spin-Peierls transition in alpha'--NaV2O5 by infrared reflectivity
D. Smirnov, P. Millet, J. Leotin +4
Polarized infrared reflectivity measurements have been performed on single crystals of the spin-Peierls compound alpha'-NaV2O5 in the temperature range 20-300 K. Pronounced spectra…
