Some Applications of the Lee-Yang Theorem

For lattice systems of statistical mechanics satisfying a Lee-Yang property (i.e., for which the Lee-Yang circle theorem holds), we present a simple proof of analyticity of (connected) correlations as functions of an external magnetic field h, for Re h > 0 or Re h < 0. A survey of models known to have the Lee-Yang property is given. We conclude by describing various applications of the aforementioned analyticity in h.Comment: 16 page

Yang-Lee Zeros of the Ising model on Random Graphs of Non Planar Topology

We obtain in a closed form the 1/N^2 contribution to the free energy of the two Hermitian N\times N random matrix model with non symmetric quartic potential. From this result, we calculate numerically the Yang-Lee zeros of the 2D Ising model on dynamical random graphs with the topology of a torus up to n=16 vertices. They are found to be located on the unit circle on the complex fugacity plane. In order to include contributions of even higher topologies we calculated analytically the nonperturbative (sum over all genus) partition function of the model Z_n = \sum_{h=0}^{\infty} \frac{Z_n^{(h)}}{N^{2h}} for the special cases of N=1,2 and graphs with n\le 20 vertices. Once again the Yang-Lee zeros are shown numerically to lie on the unit circle on the complex fugacity plane. Our results thus generalize previous numerical results on random graphs by going beyond the planar approximation and strongly indicate that there might be a generalization of the Lee-Yang circle theorem for dynamical random graphs.Comment: 19 pages, 7 figures ,1 reference and a note added ,To Appear in Nucl.Phys

Gus Lee

Augustus Samuel Mein-Sun Lee was born in San Francisco on August 8, 1946, the only son of Tsung-Chi Lee and Da-Tsien Tsu. His three sisters had been born in mainland China and accompanied his mother on the difficult trek across China to India and then to the United States in 1944. There, the family rejoined Tsung-Cbi, wbo had once been a major in the Kuomintang army and who, since 1939, had been working in San Francisco for the Bank of Canton. When Gus was only five, his mother died of breast cancer, and his father, two years later, married a severe Pennsylvania Dutch woman. Gus grew up in the Panhandle and the Haight, a predominantly African American area of San Francisco, and he had a difficult time becoming accepted. He joined the Young Men\u27s Christian Association (YMCA) and learned to box

[Review of] Rachel C. Lee. The Americas of Asian American Literature: Gendered Fictions of Nation and Transnation

Rachel C. Lee acknowledges that understanding Asian American experiences merits the study of transglobal migrations of persons and capital. Rather than criticize this scholarly trend in Asian American studies (and, I would add, in ethnic studies more broadly), Lee integrates into them a greater attention to gender. Like much of historical and social scholarship, works on the Asian American diaspora tend to neglect gender. By examining how gender figures into the various ways in which four Asian American writers imagine America, Lee reminds us that gender, like race, always matters
