Using magnetostriction to measure the spin-spin correlation function and magnetoelastic coupling in the quantum magnet NiCl $_{2}$ -4SC(NH $_{2}$ ) $_{2}$

V. S. Zapf, V. F. Correa, P. Sengupta +9

We report a method for determining the spatial dependence of the magnetic exchange coupling, $dJ / d r$ , from magnetostriction measurements of a quantum magnet. The organic Ni $S = 1$ …

Tree Approximation for Spin Glass Models

Naoki Kawashima

An approximate numerical approach to spin models is proposed, in which the original lattice is transformed into a tree. This method is applied to the Edwards-Anderson spin glass mo…

Ground States of the SU(N) Heisenberg Model

Naoki Kawashima, Yuta Tanabe

The SU(N) Heisenberg model with various single-row representations is investigated by quantum Monte Carlo simulations. While the zero-temperature phase boundary agrees qualitativel…
