Wave propagation of a non-conservative compressible two-fluid model with different pressures
Zhigang Wu, Yinghui Zhang
This paper investigates the wave propagation for a non-conservative compressible two-fluid model with unequal pressures in R3. This model is novel and fundamentally distinct from t…

Wave propagation of a generic non--conservative compressible two--fluid model
Zhigang Wu, Weike Wang, Yinghui Zhang
The generalized Huygens principle for the Cauchy problem of a generic non-conservative compressible two-fluid model in R3 was established. This work fills a key gap in the theory,…

Structure of the mean-field yrast spectrum of a two-component Bose gas in a ring: role of interaction asymmetry
Hui Tang, Guan-Hua Huang, Shizhong Zhang +2
The mean-field yrast spectrum of an SU(2)-symmetric two-component Bose gas confined to a ring geometry is known to exhibit an intricate nonanalytic structure that is absent in sing…
