Unified theory of quantum many-particle systems
Yu-Liang Liu
Using eigen-functional bosonization method, we study quantum many-particle systems, and show that the quantum many-particle problems end in to solve the differential equation of th…
Influence of gauge fluctuations on fermion pairing order parameter
Yu-Liang Liu
Using a prototype model, we study the influence of gauge fluctuations on fermion pairing order parameter which has the gauge symmetry, and demonstrate that the gauge fluctuations c…
Unified thoery of strongly correlated electron systems
Yu-Liang Liu
In framework of eigen-functional bosonization method, we introduce an imaginary phase field to uniquely represent electron correlation, and demonstrate that the Landau Fermi liquid…
Eigen-functional bosonization and Eikonal-type equations in one-dimensional strongly correlated electron system
Yu-Liang Liu
With the eigen-functional bosonization method, we study one-dimensional strongly correlated electron systems with large momentum ( and/or ) transfer term(s), and de…
Normal state property of the t-J model
Yu-Liang Liu
Using the spin-hole coherent state representation and taking a long range antiferromagnetic Nèel order as a background of the localized spin degree part, we have studied the normal…
The Magnetic Behavior of the t-J Model
Yu-Liang Liu
Using the spin-hole coherent state representation, and taking the long range antiferromagnetic Néel order as the background of the spin degree part, we have studied the magnetic be…
