In this seminar, I will give an introduction to the Quantum Monte Carlo technique (Stochastic Series Expansion) I am using to study Quantum Phase Transitions in low-dimensional magnets. As an application, I will specifically present my recent simulations on two-dimensional antiferromagnets with coupling anisotropies. In order to extract critical exponents I will discuss finite-size scaling of my data. |
