Dimer and Néel order-parameter fluctuations in the spin-fluid phase of the s=1/2 spin chain with first and second neighbor couplings
Yongmin Yu, Gerhard Müller, V. S. Viswanath
The dynamical properties at T=0 of the one-dimensional (1D) s=1/2 nearest-neighbor (nn) XXZ model with an additional isotropic next-nearest-neighbor (nnn) coupling are investigated…

Dynamics of quantum spin systems in dimer and valence-bond solid ground states stabilized by competing interactions
Yongmin Yu, Gerhard Müller
For special coupling ratios, the one-dimensional (1D) s=1/2 Heisenberg model with antiferromagnetic nearest and next-nearest neighbor interactions has a pure dimer ground state, an…
