Kondo-like State in a Simple Model for Metallic Glasses
1980
Physical Review Letters
Simple model is constructed for the tunneling two level systems inter acting with the conduction electrons in metallic glasses. The coupling con stants do not commute in the momentum space. Scaling theory shows a strong similarity with the antiferromagnetic Kondo effect and it is shówn that at low temperature a bound state is formed in which the motion of the tunneling atom and the angular dependence of the screening electron cloud varying in time are strongly correlated.
