Nature of the Quantum Phase Transition in Clean, Itinerant Heisenberg Ferromagnets
T. R. Kirkpatrick, D. Belitz
A comprehensive theory of the quantum phase transition in clean, itinerant Heisenberg ferromagnets is presented. It is shown that the standard mean-field description of the transit…

Fluctuation-Driven Quantum Phase Transitions in Clean Itinerant Ferromagnets
D. Belitz, T. R. Kirkpatrick
The quantum phase transition in clean itinerant ferromagnets is analyzed. It is shown that soft particle-hole modes invalidate Hertz's mean-field theory for . A renormali…
