Soft modes, Gaps and Magnetization Plateaus in 1D Spin-1/2 Antiferromagnetic Heisenberg Models
A. Fledderjohann, C. Gerhardt, M. Karbach +2
We study the one-dimensional spin-1/2 model with nearest and next-to-nearest-neighbor couplings exposed to a homogeneous magnetic field and a dimer field with period an…

The 1D spin-1/2 AF-Heisenberg model in a staggered field
A. Fledderjohann, M. Karbach, K. -H. Mütter
We investigate the scaling properties of the excitation energies and transition amplitudes of the one-dimensional spin- antiferromagnetic Heisenberg model exposed to an e…
