Quantum Monte Carlo Simulations on S=1/2 antiferromagnetic-Ferromagnetic Random Alternating spin chain
Peng Zhang, Zhaoxin Xu, Heping Ying +1
The S=1/2 Heisenberg chain with bond alternation and randomness of antiferromagnetic (AFM) and ferromagnetic (FM) interactions is investigated by quantum Monte Carlo simulations of…

Critical dynamics and universality of the random-bond Potts ferromagnet with tri-distributed quenched disorders
H. P. Ying, B. J. Bian, D. R. Ji +2
Critical behavior in short-time dynamics is investigated by a Monte Carlo study for the random-bond Potts ferromagnet with a trinary distribution of quenched disorders on two-dimen…

A determination of the low energy parameters of the 2-d Heisenberg antiferromagnet
U. -J. Wiese, H. -P. Ying
We perform numerical simulations of the 2-d antiferromagnetic quantum Heisenberg model using an efficient cluster algorithm. Comparing the finite size and finite temperature effect…
