Criticality in inhomogeneous magnetic systems: Application to quantum ferromagnets
D. Belitz, T. R. Kirkpatrick, Ronojoy Saha
We consider a -theory with a position-dependent distance from the critical point. One realization of this model is a classical ferromagnet subject to non-uniform mechanical st…
