Solving and Completing the Rabi-Stark Model in the Ultrastrong Coupling Regime
Gen Li, Hao Zhu, Guo-Feng Zhang
In this work,we employ a unitary transformation with a suitable parameter to convert the quantum Rabi-Stark model into a Jaynes-Cummings-like model. Subsequently, we derive the ana…
Three-dimensional Isotropic Droplets in Rydberg-dressed Bose Gases
Hao Zhu, Yong-Yao Li, Wen-Kai Bai +3
We predict a scheme for the creation of isotropic three-dimensional droplets in Rydbeg-dressed Bose gases, which contain both repulsive contact interactions and attractive van der…
Nonlinear stability of non-rotating gaseous stars
Zhiwu Lin, Yucong Wang, Hao Zhu
For the non-rotating gaseous stars modeled by the compressible Euler-Poisson system with general pressure law, Lin and Zeng [18] proved a turning point principle, which gives the s…
On the stability and instability of Kelvin-Stuart cat's-eye flows
Shasha Liao, Zhiwu Lin, Hao Zhu
Kelvin-Stuart vortices are classical mixing layer flows with many applications in fluid mechanics, plasma physics and astrophysics. We prove that the whole family of Kelvin-Stuart…
Pion-mediated Cooper pairing of neutrons: beyond the bare vertex approximation
Hao-Fu Zhu, Guo-Zhu Liu
In some quantum many particle systems, the fermions could form Cooper pairs by exchanging intermediate bosons. This then drives a superconducting phase transition or a superfluid t…
Fermion dispersion renormalization in a two-dimensional semi-Dirac semimetal
Hao-Fu Zhu, Xiao-Yin Pan, Guo-Zhu Liu
We present a non-perturbative study of the quantum many-body effects caused by the long-range Coulomb interaction in a two-dimensional semi-Dirac semimetal. This kind of semimetal…
Transitions to improved confinement regimes induced by changes in heating in zero-dimensional models for tokamak plasmas
H. Zhu, S. C. Chapman, R. O. Dendy +1
It is shown that rapid substantial changes in heating rate can induce transitions to improved energy confinement regimes in zero-dimensional models for tokamak plasma phenomenology…
Robustness of predator-prey models for confinement regime transitions in fusion plasmas
H. Zhu, S. C. Chapman, R. O. Dendy
Energy transport and confinement in tokamak fusion plasmas is usually determined by the coupled nonlinear interactions of small-scale drift turbulence and larger scale coherent non…
