The correlation length $\xi$ is related to critical temperature $T_c$ as $$ \xi\sim|T-T_{c}|{}^{-\nu}, $$
where $\nu$ is the critical exponent.
- Is this the formal definition of correlation length? If not, what is the formal definition of correlation length (for phase transition in the Ising model)?
- Can you give a physical understanding of correlation length?
