Beyond Fermi-Liquid Theory: the -Fermi liquids
Tai-Kai Ng
We study in this paper the general properties of a many body system of fermions in arbitrary dimensions assuming that the {\em momentum} of individual fermions are good quantum num…
Generalized Falicov-Kimball Models
Xiao-Hui Li, Zewei Chen, Tai-Kai Ng
In this paper we extend the Falicov-Kimball model (FKM) to the case where the "quasi-particles" entering the FKM are not "ordinary" fermions. As an example we first discuss how the…
Luttinger theorem and low energy properties of ideal Haldane-Sutherland Liquids
Tai Kai Ng
We study in this paper the properties of a many body system of fermions obeying exclusion-statistics (Haldane liquid) where the origin of exclusion statistics is coming from an int…
An exactly solvable BCS-Hubbard Model in arbitrary dimensions
Zewei Chen, Xiaohui Li, Tai Kai Ng
We introduce in this paper an exact solvable BCS-Hubbard model in arbitrary dimensions. The model describes a p-wave BCS superconductor with equal spin pairing moving on a bipartit…
Magnetic properties of 2D topological insulators
Zewei Chen, Tai Kai Ng
The effects of Hubbard-type on-site interactions on the BHZ model is studied in this paper for model parameters appropriate for the HgTe/CdTe quantum well. Within a simple mean fie…
Fermi liquid theory - A Fermi liquid state that supports exclusion statistics
Tai-Kai Ng
We propose in this paper an effective low-energy theory for interacting fermion systems which supports exclusion statistics. The theory can be viewed as an extension of Landau Ferm…
