Doping-induced energy gap in a quantum spin chain
SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless... -
Spin dynamics in a doped S=1/2 Heisenberg Antiferromagnetic chain SrCuO2
We propose to microscopically study the role of defects on spin transport in one of the best approximations to the ideal antiferromagnetic Heisenberg s = ½ chain. By measuring... -
Crossover between diffusive and ballistic transport regimes in the S=1/2 Heis...
The question of whether the spin transport in an S=1/2 Heisenberg antiferromagnetic chain is ballistic or diffusive remains intensely discussed theoretically and studied...
