Bloch Walls and Macroscopic String States in Bethe's solution of the Heisenberg Ferromagnetic Linear Chain

Abhishek Dhar, B Sriram Shastry

We present a calculation of the lowest excited states of the Heisenberg ferromagnet in 1-d for any wave vector. These turn out to be string solutions of Bethe's equations with a ma…

Equilibrium and dynamical properties of the ANNNI chain at the multiphase point

Abhishek Dhar, B. Sriram Shastry, Chandan Dasgupta

We study the equilibrium and dynamical properties of the ANNNI (axial next-nearest-neighbor Ising) chain at the multiphase point. An interesting property of the system is the macro…
