Cuprate d-wave superconductivity based on Non perturbative many body theory for spin fluctuation
Jianwei Gong, Junnian Xiong, Ruitao Xiao +4
We employ the nonperturbative many-body spin GW method to compute the single-particle Green's function, and the covariance method to evaluate the two-body correlation functions, fo…
Benchmarking Non-perturbative Many-Body Approaches in the Exactly Solvable Hatsugai-Kohmoto Model
Hui Li, Ziyu Li, Chen-run Yu
The accurate simulation of strongly correlated electron systems remains a central challenge in condensed matter physics, motivating the development of various non-perturbative many…
Emergent Composite Particles from the Universal Exact Identities in Quantum Many-Body Systems with Generic Bilinear Interactions
Hui Li
A fundamental challenge in quantum many-body physics is to understand the universal properties of strongly correlated systems. In this work, we establish a universal and exact iden…
Quantum Quench Dynamics in an Exactly Solvable Two-Dimensional Non-Fermi Liquid System
Hui Li, Run-Yu Chen, Wen-Yuan Liu +2
Understanding the behavior of non-Fermi liquids (NFLs) is an important topic in condensed matter physics. Here we introduce an exactly solvable multi-orbital model based on iron ox…
Experimental demonstration of generalized quantum fluctuation theorems in the presence of coherence
Hui Li, Jie Xie, Hyukjoon Kwon +3
Fluctuation theorems have elevated the second law of thermodynamics to a statistical realm by establishing a connection between time-forward and time-reversal probabilities, provid…
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…
