Nonpertubative Many-Body Theory for the Two-Dimensional Hubbard Model at Low Temperature: From Weak to Strong Coupling Regimes
Ruitao Xiao, Yingze Su, Junnian Xiong +3
In theoretical studies of two-dimensional (2D) systems, the Mermin-Wagner theorem prevents continuous symmetry breaking at any finite temperature, thus forbidding a Landau phase tr…
Application of Many-body Non-perturbative Theories to the Three-Dimensional Attractive Hubbard Model
Junnian Xiong, Hui Li, Yingze Su +1
The attractive Fermi-Hubbard model stands out as a simple model for studying the pairing and superconductivity of fermions on a lattice. In this article, we apply several many-body…
Post- theory and its application to pseudogap in strongly correlated system
Hui Li, Yingze Su, Junnian Xiong +3
The approximation is a widely used framework for studying correlated materials, but it struggles with certain limitations, such as its inability to explain pseudogap phenomena…
Effects of the pseudogap and the Fermi surface on the rapid Hall-coefficient changes in cuprates
Yingze Su, Hui Li, Huaqing Huang +1
High- cuprates are characterized by strong spin fluctuations, which give rise to antiferromagnetic and pseudogap phases and may be key to the high superconducting critical tem…
Linear Response Functions Respecting Ward-Takahashi Identity and Fluctuation-Dissipation Theorem within Approximation
Hui Li, Zhipeng Sun, Yingze Su +3
The calculation of response functions in correlated electronic systems is one of the most important problems in the condensed matter physics. To obtain a physical response function…
