摘要：
Characteristic properties of the dressed particles, holon and spinon, in the one dimensional correlated electron systems are investigated by means of the exact solution of the Hubbard model. In particular, the nature of holon is clarified in detail in the system close to the Mott insulating phase. The dressed particles in magnetic fields are also formulated and discussed in terms of the bulk quantities. The exact results obtained for the correlation functions are mentioned in connection with the fractional charge of the dressed particles.
