Multi-magnon bound states in easy-axis ferromagnetic zigzag spin chain
D. V. Dmitriev, V. Ya. Krivnov
The frustrated spin-1/2 chain with weakly anisotropic ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor exchanges is studied. We focus on the excitation sp…

Quasi-one-dimensional anisotropic Heisenberg model in a transverse magnetic field
D. V. Dmitriev, V. Ya. Krivnov
The phase diagram of weakly coupled chains in a transverse magnetic field is studied using the mean-field approximation for the interchain coupling and known exact results fo…

The antiferromagnetic Ising chain in a mixed transverse and longitudinal magnetic field
A. A. Ovchinnikov, D. V. Dmitriev, V. Ya. Krivnov +1
We have studied the antiferromagnetic Ising chain in a transverse magnetic field and uniform longitudinal field . Using the density matrix renormalization group calc…
