Polarized image of a rotating black hole in Scalar-Tensor-Vector-Gravity theory
Xin Qin, Songbai Chen, Zelin Zhang +1
The polarized images of a synchrotron emitting ring are studied in the spacetime of a rotating black hole in the Scalar-Tensor-Vector-Gravity (STVG) theory. The black hole owns an…
Image of Bonnor black dihole with a thin accretion disk and its polarization information
Zelin Zhang, Songbai Chen, Jiliang Jing
We have studied the image of Bonnor black dihole surrounded by a thin accretion disk where the electromagnetic emission is assumed to be dominated respectively by black body radiat…
A semi-analytical solution to the forward-reverse shock hydrodynamics of the gamma-ray burst afterglow
Ze-Lin Zhang, Ruo-Yu Liu, Jin-Jun Geng +2
We extend the standard model of forward-reverse shock (FS-RS) for gamma-ray burst (GRB) afterglow to more general cases. On one hand, we derive the analytical solution to the hydro…
Interpretation of the light curve of GeV-TeV emission from the 2021 outburst of the recurrent nova RS Ophiuchi
Jian-He Zheng, Yi-Yun Huang, Ze-Lin Zhang +3
Nova outbursts take place in binary star systems comprising a white dwarf (WD) and either a low-mass Sun-like star (classical novae) or, a red giant. GeV gamma-ray emission has bee…
Acceleration of ultra-high energy cosmic rays in the early afterglows of gamma-ray bursts: concurrence of jet's dynamics and wave-particle interactions
Ze-Lin Zhang, Ruo-Yu Liu, Xiang-Yu Wang
The origin of ultra-high energy cosmic rays UHECRs remains a mystery. It has been suggested that UHECRs can be produced by the stochastic acceleration in relativistic jets of…
Tracking quantum state evolution by the Berry curvature with a two-level system
Ze-Lin Zhang, Ping Xu, Zhen-Biao Yang
We investigate two kinds of topological structures (sphere and torus) spanned by the controlled parameters of a driven two-level system's Hamiltonian, and consider the connection b…
Quantum simulation of gravitational-like waves in minisuperspace with an artificial qubit
Ze-Lin Zhang, Ming-Feng Chen, Huai-Zhi Wu +1
On the background of the Born-Oppenheimer (adiabatic) approximation, we investigate the geometrical and topological structure in the theory of quantum gravity by using the path int…
Quantum simulation of Abelian Wu-Yang monopoles in spin-1/2 systems
Ze-Lin Zhang, Ming-Feng Chen, Huai-Zhi Wu +1
With the help of the Berry curvature and the first Chern number , we both analytically and numerically investigate and thus simulate artificial magnetic monopol…
