R. Chaudhury et D. Gangopadhyay, INTERACTING FERMIONS, SCALING AND POSSIBLE DEPARTURE FROM FERMI-LIQUID BEHAVIOR, Modern physics letters B, 9(25), 1995, pp. 1657-1664
We study fermionic models with realistic interaction in the low energy
limit by scaling energies. We show that there exist possibilities for
a departure from the Fermi liquid picture in two dimensions.
