Magnetic Phase Diagram of Spin-1/2 Two-Leg Ladder with Four-Spin Ring Exchange
Toshiya Hikihara, Shoji Yamamoto
We study the spin-1/2 two-leg Heisenberg ladder with four-spin ring exchanges under a magnetic field. We introduce an exact duality transformation which is an extension of the spin…

Spin coupling in zigzag Wigner crystals
A. D. Klironomos, Julia S. Meyer, T. Hikihara +1
We consider interacting electrons in a quantum wire in the case of a shallow confining potential and low electron density. In a certain range of densities, the electrons form a two…
