Quantum-Corrected Q-balls in the Friedberg-Lee-Sirlin Model
Yong-Xiang Su, Qi-Xin Xie, Shuang-Yong Zhou
We study the real-time quantum dynamics of Q-balls in the Friedberg-Lee-Sirlin model within the inhomogeneous Hartree approximation. The mean fields are evolved self-consistently w…
Quantum fields in boson star spacetime
Paul M. Saffin, Qi-Xin Xie
Boson stars have been extensively studied in classical gravity, but their quantum properties remain comparatively unexplored. In this paper, we compute the quantum scalar fields an…
Superradiance of Friedberg-Lee-Sirlin Solitons
Guo-Dong Zhang, Cheng-Hao Li, Qi-Xin Xie +1
It has recently been pointed out that rotation in internal space can induce superradiance. We explore this effect in non-topological solitons of the two-field Friedberg-Lee-Sirlin…
Spinning -ball Superradiance in 3+1D
Guo-Dong Zhang, Fu-Ming Chang, Paul M. Saffin +2
Recently, it has been found that a -ball can amplify waves incident upon it, due to rotation in the internal space and the interaction of the two modes in the complex scalar fie…
Quantum corrected Q-ball dynamics
Qi-Xin Xie, Paul M. Saffin, Anders Tranberg +1
The physics of individual Q-balls and interactions between multiple Q-balls are well-studied in classical numerical simulations. Interesting properties and phenomena have been disc…
Boson Star Superradiance
He-Yu Gao, Paul M. Saffin, Yi-Jie Wang +2
Recently, it has been realized that in some systems internal space rotation can induce energy amplification for scattering waves, similar to rotation in real space. Particularly, i…
