Three-dimensional O(N) -invariant ϕ4 models at criticality for N≥4
Martin Hasenbusch B
Abstract
We study the $O(N)$-invariant ${\ensuremath{\phi}}^{4}$ model on the simple cubic lattice by using Monte Carlo simulations. By using a finite-size scaling analysis, we obtain accurate estimates for the critical exponents $\ensuremath{\nu}$ and $\ensuremath{\eta}$ for $N=4$, 5, 6, 8, 10, and 12. We study the model for each $N$ for at least three different values of the parameter $\ensuremath{\lambda}$ to control leading corrections to scaling. We compare our results with those obtained by other theoretical methods.
