Magnetic and Critical Properties of Alternating Spin Heisenberg Chain in a Magnetic Field | | T. Kuramoto
; | | Date: |
22 Oct 1997 | | Subject: | Statistical Mechanics | cond-mat.stat-mech | | Abstract: | We study magnetic and critical properties of the alternating spin antiferromagnetic Heisenberg chain with $S=1/2$ and 1 in a magnetic field at T=0. The numerical diagonalization is applied to the system up to $2N=20$ sites. Checking numerically that magnetic states with the magnetization per site $m$ obey a conformal field theory with conformal anomaly $c=1$ for $1/4 | | Source: | arXiv, cond-mat/9710229 | | Services: | Forum | Review | PDF | Favorites | |
