Green's Function-Free Formalism of Projective Truncation Approximation
Kou-Han Ma, Yue-Hong Wu, Ning-Hua Tong
In previous works, the projected truncation approximation (PTA) was developed as a systematic and controlled method to truncate the equation of motion of Green's functions (GFs) fo…
Positive Correlation between Heavy Alcoholic Drinking and SARS-Cov-2 Not-infection Rate
Ning-Hua Tong, Pietro Salvatori
An investigation on the correlation between the strong alcoholic drinking and SARS-Cov-2 uninfection rate is carried out. The investigation is done through a simple survey in China…
Kondo Phase in Twisted Bilayer Graphene -- A Unified Theory for Distinct Experiments
Geng-Dong Zhou, Yi-Jie Wang, Ninghua Tong +1
A number of interesting physical phenomena have been discovered in magic-angle twisted bilayer graphene (MATBG), such as superconductivity, correlated gapped and gapless phases, et…
Spatial spin-spin correlations of the single-impurity Anderson model with a ferromagnetic bath
Peng Fan, Ning-Hua Tong, Zhen-Gang Zhu
We investigate the interplay between the Kondo effect and the ferromagnetism by an one dimension Anderson impurity model with a spin partially polarized bath, using the projective…
Projective-truncation-approximation study of the one-dimensional lattice model
Kou-Han Ma, Yan-Jiang Guo, Lei Wang +1
In this paper, we first develop the projective truncation approximation (PTA) in the Green's function equation of motion (EOM) formalism for classical statistical models. To implem…
Interacting spinless fermions on the square lattice: Charge order, phase separation, and superconductivity
Kou-Han Ma, Ning-Hua Tong
We investigate the phase diagram of spinless fermions on a square lattice with nearest-neighbor interaction, using the recently developed projective truncation approximation in Gre…
