High-order rogue waves of a long wave-short wave model

The long wave-short wave model describes the interaction between the long wave and the short wave. Exact higher-order rational solution expressed by determinants is calculated via the Hirota's bilinear method and the KP hierarchy reduction. It is found that the fundamental rogue wave for the short wave can be classified into three different patterns: bright, intermediate and dark ones, whereas the rogue wave for the long wave is always bright type. The higher-order rogue waves correspond to the superposition of fundamental rogue waves. The modulation instability analysis show that the condition of the baseband modulation instability where an unstable continuous-wave background corresponds to perturbations with infinitesimally small frequencies, coincides with the condition for the existence of rogue-wave solutions.Comment: 14 pages, 5 figure

Szu-Feng Chen, Assistant Professor, Department of Theatre and Dance, travels to Singapore

Professor Szu-Feng Chen was invited by The Theatre Practice (TTP) in Singapore to create set and costume design for Lao Jiu: The Musical, its feature musical production for the Singapore Kuo Pao Kun Festival.I was invited by The Theatre Practice (TTP) in Singapore to create set and costume design for its feature musical production for Singapore Kuo Pao Kun Festival. Lao Jiu: The Musical, is a musical version of Kuo’s signature play. It was opened in July 2012 in memory of ten years of Kuo Pao Kun’s passing. Kuo Pao Kun was the pioneer and art educator of Singaporean theatre—awarded the National Culture Medallion in 1989, the Culture Award in 1992, Asean Cultural Award in 1993and the Excellence for Singapore Award in 2002. The festival is hosted by The Theatre Practice and supported by Singapore National Arts Council in honor of Kuo’s contribution to the Singapore performing arts

Rare Decays

Studies of rare decays play an important role in the search of physics beyond the standard model. New particles may participate in the loop processes and can be probed by seeing any deviations from the standard model predictions. The very rare decay $B_s\to\mu^+\mu^-$ has been observed with the data collected by CMS and LHCb experiments. The signal seen by the ATLAS experiment is less significant but is compatible with the predictions. The measurement itself provides stringent constraints to new physics models. The first effective lifetime measurement with $B_s\to\mu^+\mu^-$ candidates has been carried out by the LHCb experiment. More data are still required to observe the $B^0\to\mu^+\mu^-$ decays. The $B\to K^*\mu^+\mu^-$ decay also proceeds through a flavour changing neutral current process, and is sensitive to the new physics. Extended measurements are carried out for $B\to K^*\mu^+\mu^-$ decays. Most of the classical physics parameters are found to be consistent with the predictions, but tensions do emerge in some of the observables. More data will help to clarify these potential deviations.Comment: 7 pages, for LHCP 2017 conferenc
