PERTURBATION THEORY OF TRANSVERSE TRANSPORT PROCESS IN STRONG MAGNETIC FIELD

The transport process in strong magnetic field,because of its simplicity and specifi-city,is interesting for theoretical investigation.The“strong magnetic field”called abovemeans that the product of the Lamor frequency ω=eH/mc and the relaxation time τis larger or much larger than one,i.e.,ωτ>1 or ωτ>>1.In the extreme caseωτ>1,the transverse transport process is one of the simplest and typical examples ofthe transport process of the local states.The spatial arrangement of these local states is
