如果这学期社课有成行的话，我十一月中回去可以带个一到两次。上次回去好像因为
暂时没有活动，所以也没和大家见到面。
主题应该会是 Renormalization group approach to 1D Kuramoto-like system.
可参考:
T. E. Lee, G. Refael, M. C. Cross, O. Kogan, and J. L. Rogers, Universality
in the one-dimensional chain of phase-coupled oscillators, Phys. Rev. E 80,

O. Kogan, J. L. Rogers, M. C. Cross, and G. Refael, Renormalization group
approach to oscillator synchronization, Phys. Rev. E 80, 036206 (2009)

说要成行，我才发觉前置作业不算少。
