Annealed disorder, rare regions, and local moments: A novel mechanism for metal-insulator transitions
D. Belitz, T. R. Kirkpatrick, Thomas Vojta
Local magnetic moments in disordered sytems can be described in terms of annealed magnetic disorder, in addition to the underlying quenched disorder. It is shown that for nonintera…
Quantum critical behavior of itinerant ferromagnets
Thomas Vojta, D. Belitz, T. R. Kirkpatrick +1
We investigate the quantum phase transition of itinerant ferromagnets. It is shown that correlation effects in the underlying itinerant electron system lead to singularities in the…
The disordered Fermi-liquid fixed point and its instabilities
D. Belitz, T. R. Kirkpatrick
The concept of a disordered Fermi-liquid fixed point is introduced and used to understand various properties of disordered metals within a unifying framework. Corrections to scalin…
On the critical behavior of disordered quantum magnets: The relevance of rare regions
R. Narayanan, Thomas Vojta, D. Belitz +1
The effects of quenched disorder on the critical properties of itinerant quantum antiferromagnets and ferromagnets are considered. Particular attention is paid to locally ordered s…
Influence of rare regions on magnetic quantum phase transitions
R. Narayanan, Thomas Vojta, D. Belitz +1
The effects of quenched disorder on the critical properties of itinerant quantum magnets are considered. Particular attention is paid to locally ordered rare regions that are forme…
