Three-dimensional $O(N)$-invariant $\phi^4$ models at criticality for $N\ge 4$

Understand

We study the $O(N)$-invariant $\phi^4$ 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 $\nu$ and $\eta$ 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 $\lambda$ to control leading corrections to scaling.
• We compare our results with those obtained by other theoretical methods.
