Slave Boson Approach to the One Dimensional t-J Model

摘要: The one-dimensional t-J model is studied using functional integral approach. separation of spin and charge degrees freedom treated in the slave boson representation. density response function calculated when holes are described by bosons as well spinless fermions a la Jordan-Wigner transformation. We show that long wavelength limit can be mapped onto Tomonaga-Luttinger model. forward scattering amplitudes g 2 4 electron momentum distribution exponent α obtained terms parameters.
