Quantum critical behavior in disordered itinerant ferromagnets: Instability of the ferromagnetic phase
An effective field theory is derived, which describes the quantum critical behavior of itinerant ferromagnets, as the transition is approached from the ferromagnetic phase. This complements a recent study of the critical behavior on the paramagnetic side of the phase transition, and investigates the role of the ferromagnetic Goldstone modes near criticality. We find that the Goldstone modes hav...
متن کاملMetal-Insulator Transition in Disordered and Interacting Electron Systems
For a system of interacting electrons moving in a random potential, it is shown that screening by the Coulomb interaction suppresses long-wavelength potential fluctuations. As a result, the lower critical dimensionality for metal-insulator transition is reduced from the noninteracting value of 2 to 4/3. Therefore there is a transition in two dimensions, consistent with recent experiments. For a...
متن کاملMetal-insulator transition in disordered two-dimensional electron systems.
We present a theory of the metal-insulator transition in a disordered two-dimensional electron gas. A quantum critical point, separating the metallic phase, which is stabilized by electronic interactions, from the insulating phase, where disorder prevails over the electronic interactions, has been identified. The existence of the quantum critical point leads to a divergence in the density of st...
متن کاملPhase Transition in Disordered Quantum Systems: Transverse Ising Models
We introduce the transverse Ising model as a prototype for discussing quantum phase transition. Mean field theory, application to superconductivity by BCS and real space renormalization group technique (in one dimension) are discussed. Next we introduce Suzuki-Trotter formalism to show the correspondence between d-dimensional quantum system with a (d + 1)-dimensional classical system. We then d...
متن کاملLocal field theory for disordered itinerant quantum ferromagnets
An effective field theory is derived that describes the quantum critical behavior of itinerant ferromagnets in the presence of quenched disorder. In contrast to previous approaches, all soft modes are kept explicitly. The resulting effective theory is local and allows for an explicit perturbative treatment. It is shown that previous suggestions for the critical fixed point and the critical beha...
