L. Hubert et C. Bourbonnais, QUASI-1D CONDUCTORS UNDER MAGNETIC-FIELD - A UNIFIED POINT-OF-VIEW FROM A QUANTUM RENORMALIZATION-GROUP APPROACH, Synthetic metals, 57(2-3), 1993, pp. 4231-4236
We apply the functional integral quantum renormalization group method
to quasi-one-dimensional (Q-1D) metallic systems under magnetic field.
For spinless fermions with intrachain forward scattering interaction,
the expressions for the critical temperatures in low and high magneti
c field regimes are given. Application of the results to the phase dia
grams of (TMTSF)2ClO4 and (TMTSF)2PF6 under magnetic field is briefly
discussed.
