Quantitative Entropy Study of Language ComplexityNov 14 2016We study the entropy of Chinese and English texts, based on characters in case of Chinese texts and based on words for both languages. Significant differences are found between the languages and between different personal styles of debating partners. ... More

The binary mass transfer origin of the red blue straggler sequence in M30Jan 07 2015Two separated sequences of blue straggler stars (BSSs) have been revealed by Ferraro et al. (2009) in the color-magnitude diagram (CMD) of the Milky Way globular cluster M30. Their presence has been suggested to be related to the two BSS formation channels ... More
Magnetic Correlations in the Two-dimensional Repulsive Fermi Hubbard ModelJun 23 2017The repulsive Fermi Hubbard model on the square lattice has a rich phase diagram near half-filling (corresponding to the particle density per lattice site $n=1$): for $n=1$ the ground state is an antiferromagnetic insulator, at $0.6 < n \lesssim 0.8$, ...
