Projection of Infinite- Hubbard Model and Algebraic Sign Structure
Yunqing Ouyang, Xiao Yan Xu
We propose a projection approach to perform quantum Monte Carlo (QMC) simulation on the infinite- Hubbard model at some integer fillings where either it is sign problem free or…
Computing classification of interacting fermionic symmetry-protected topological phases using topological invariants
Yunqing Ouyang, Qing-Rui Wang, Zheng-Cheng Gu +1
In recent years, great success has been achieved on the classification of symmetry-protected topological (SPT) phases for interacting fermion systems by using generalized cohomolog…
Equivalent-neighbor percolation models in two dimensions: crossover between mean-field and short-range behavior
Yunqing Ouyang, Youjin Deng, Henk W. J. Blöte
We investigate the influence of the range of interactions in the two-dimensional bond percolation model, by means of Monte Carlo simulations. We locate the phase transitions for se…
Solar Filament Longitudinal Oscillations along a Magnetic Field Tube with Two Dips
Yu-Hao Zhou, Li-Yue Zhang, Y. Ouyang +2
The large-amplitude longitudinal oscillations of solar filaments have been observed and explored for more than ten years. Previous studies are mainly based on the one-dimensional r…
Chirality and Magnetic Configurations of Solar Filaments
Y. Ouyang, Y. H. Zhou, P. F. Chen +1
It has been revealed that the magnetic topology in the solar atmosphere displays hemispheric preference, i.e., negative/positive helicity in the northern/southern hemisphere, respe…
Is flux rope a necessary condition for the progenitor of coronal mass ejections?
Y. Ouyang, K. Yang, P. F. Chen
A magnetic flux rope structure is believed to exist in most coronal mass ejections (CMEs). However, it has been long debated whether the flux rope exists before eruption or is form…
