This constant is the zero mode of the field, and plays the role of a Lagrange multiplier for the remaining low– energy degrees of freedom. You used Lagrange multipliers in mechanics to confine wooden beads to steel hoops. This i ...

... This dependence of the renormalized temperature Tren (τ ) on a change of scale by eτ is what we call the “renormalization group flow” of Tren (τ ). The critical temperature Tc , at which the system is scale invariant, is called a fixed point of this flow. In Thermodynamics and in daily life one usua ...
