Why Quantum Phase Transitions Are Interesting
D. Belitz, T. R. Kirkpatrick
This paper discusses why the usual notion that quantum phase transitions can be mapped onto classical phase transitions in a higher dimension, and that this makes the former uninte…
Comment on ``Specific heat of a Fermi system near ferromagnetic quantum phase transition'' by Grosu, Bodea, and Crisan (cond-mat/0101392)
D. Belitz, T. R. Kirkpatrick
We comment on various incorrect claims made in a recent paper by Grosu et al. (cond-mat/0101392).
Rare regions and annealed disorder in quantum phase transitions
R. Narayanan, Thomas Vojta, D. Belitz +1
The Griffiths region that is due to rare regions and the resulting local moments in disordered itinerant quantum magnets, and its influence on the critical behavior, is considered…
Quantum phase transitions
D. Belitz, T. R. Kirkpatrick
These are notes for lectures delivered at the NATO ASI on Dynamics in Leiden, The Netherlands, in July 1998. The main concepts relating to quantum phase transitions are explained,…
Quantum kinetic theory: The disordered electron problem
T. R. Kirkpatrick, D. Belitz
These are notes for lectures delivered at the NATO ASI on Dynamics in Leiden, The Netherlands, in July 1998. The quantum kinetic theory for noninteracting electrons in a disordered…
