Replica trick
text:
In the statistical physics of spin glasses and other systems with quenched disorder, the replica trick is a mathematical technique based on the application of the formula: ln Z = lim n → 0 Z n − 1 n or: ln Z = lim n → 0 ∂ Z n ∂ n where Z is most commonly the partition function, or a similar thermodynamic function. It is typically used to simplify the calculation of E [ ln Z ], the expected value of ln Z, reducing the problem to calculating the disorder average E [ Z n ] where n is assume
