Bayesian Analysis of Massive Boson Star Models for Sagittarius A* Using Near-Infrared Astrometry Data
Xiangyu Wang, Tian-chi Ma, Minyong Guo +1
Assuming that the compact source at the Galactic center, Sagittarius A*, is a massive boson star, we fit the near-infrared flare astrometry data. We consider 12 discrete boson star…
Dynamics of kinks in a traversable wormhole
Tian-Chi Ma, Hai-Qing Zhang
We investigate the dynamics of spherically symmetric radial domain walls (or kinks) in a traversable Simpson-Visser wormhole. By solving the scalar field in a double-well potential…
Radial kinks in the boson stars
Tian-Chi Ma, Xiang-Yu Wang, Hai-Qing Zhang
In this work, we study the time evolution of radial kinks in the background of boson stars. In particular, we consider two types of boson stars: the massive boson star and the soli…
Universal Critical Holography and Domain Wall Formation
Tian-Chi Ma, Han-Qing Shi, Hai-Qing Zhang +1
Using holography, we study the universal scaling laws governing the coarsening dynamics of strongly coupled domain walls. Specifically, we studied the universal dependence of the l…
Asymmetric Symmetry Breaking: Unequal Probabilities of Vacuum Selection
Tian-Chi Ma, Han-Qing Shi, Hai-Qing Zhang
Spontaneous symmetry breaking is a fundamental notion in modern physics, ranging from high energy to condensed matter. However, the usual spontaneous symmetry breaking only conside…
Topologically Protected Metastable States in Classical Dynamics
Han-Qing Shi, Tian-Chi Ma, Hai-Qing Zhang
We propose that domain walls formed in a classical Ginzburg-Landau model can exhibit topologically stable but thermodynamically metastable states. This proposal relies on Allen-Cah…
