A one band Hubbard model with intermediate coupling is shown to describe the two most
important unusual features of a normal state: linear resistivity strange metal and the …

This study applies the time-dependent Ginzburg–Landau (TDGL) theory with thermal noise
to analyze the thermoelectric and transport properties of superconducting Sn nanowires …

We develop a nonlinear theory of the electronic transport in superconductors in the
framework of the time-dependent Ginzburg-Landau (TDGL) equation. We utilize self …

Fundamental equalities, such as the Ward-Takahashi identity (WTI) and the fluctuation-
dissipation theorem (FDT), are important in the calculation of the response functions, which …

A modified GW approximation to many-body systems is developed. The approximation has
the same computational complexity as the traditional GW approach, but uses a different …

A nonlinear theory of the electronic transport in superconductors under magnetic field in the
framework of the three-dimensional Ginzburg–Landau model with thermal fluctuation is …

Mean field approach, although a generally reliable tool that captures major short-range
correlations, often fails in symmetric low dimensional strongly correlated electronic systems …

An approximation scheme determining the excitations of an electronic model on the lattice
with pairwise interactions is proposed. A systematic truncation of the set of Dyson-Schwinger …

Strongly correlated electron systems are generally described by tight-binding lattice
Hamiltonians with strong local (onsite) interactions, the most popular being the Hubbard …

We developed a systematic non-perturbative method base on Dyson-Schwinger theory and
the derivable theory for Ising model at broken phase. Based on these methods, we obtain …
