Dysprosium-based experimental representatives of an Ising-Heisenberg chain and a decorated Ising ring
Dysprosium-based experimental representatives decorated Ising ring

It is shown that the bond-decorated Ising model is a realistic model for certain real magnetic
compounds containing lanthanide ions. The lanthanide ion plays the role of Ising spin. The re-
quired c...

The zero-temperature properties of the SO(5) bilinear-biquadratic Heisenberg spin chain are investigated by means of a low-energy approach and large scale numerical calculations. In sharp contrast to ...

The role of spin-orbit interaction, arises from the Dzyaloshinski-Moriya anisotropic antisymmetric interaction, on the entanglement transfer via an antiferromagnetic XXZ Heisenberg chain is investigat...
Thermodynamic limit of particle-hole form factors in the massless XXZ Heisenberg chain
Thermodynamic limit particle-hole XXZ Heisenberg chain

We study the thermodynamic limit of the particle-hole form factors of the XXZ Heisenberg chain in the massless regime. We show that, in this limit, such form factors decrease as an explicitly computed...

In this paper, we consider a class of compressible Heisenberg chain equations with periodic initial value problem. An explicit finite difference scheme is proposed. Moreover, its convergence and stabi...
