Analysis of minimum orbital periods around d-dimensional charged black holes
Yan Peng, Guohua Liu
This paper investigates the bounds on the minimum orbital period for test objects around d-dimensional charged black holes in asymptotically flat spacetimes. We derive the exact cr…
Bounds on the minimum orbital period of four-dimensional black holes: From singular to non-singular spacetimes
Guohua Liu, Yan Peng, Hua Huang +1
It was conjectured that the lower bound may be a universal property of four-dimensional black holes, where is the black hole mass and is the mini…
Upper bound on the radius of the innermost photonsphere in the regular compact star spacetime
Guohua Liu, Yan Peng
We study properties of the innermost photonsphere in the regular compact star background. We take the traceless energy-momentum tensor and dominant energy conditions. In the regula…
No long hair behaviors of ultra-compact objects
Guohua Liu, Yan Peng
We investigate distributions of matter fields outside spherically symmetric ultra-compact objects in the asymptotically flat background. Based on the dominant energy condition and…
A no-go theorem for scalar fields with couplings from Ginzburg-Landau models
Guohua Liu, Yan Peng
Recently Hod proved a no-go theorem that static scalar fields cannot form spherically symmetric boson stars in the asymptotically flat background. On the other side, scalar fields…
No scalar condensations outside reflecting stars with coupling terms from Ginzburg-Landau models
Guohua Liu, Yan Peng
We consider static scalar fields coupled to the gradient where the coupling also appears in next-to-leading order Ginzburg-Landau models. We study condensation behaviors of scalar…
Hawking--Page phase transitions of the black holes in a cavity
Wen-Bo Zhao, Guo-Rong Liu, Nan Li
The Hawking--Page phase transitions of the Schwarzschild and charged black holes are investigated in an extended phase space, in which the black holes are enclosed in a spherical c…
Thermodynamics of general flat space and boson star quasi-local systems
Yan Peng, Jianjun Fang, Shuangxi Yi +1
We study thermodynamics of flat space/boson star systems enclosed in a scalar reflecting box with Stckelberg mechanism. We also disclose effects of model parameters on tr…
Holographic entanglement entropy in two-order insulator/superconductor transitions
Yan Peng, Guohua Liu
We study holographic superconductor model with two scalar fields coupled to one single Maxwell field in the AdS soliton background away from the probe limit. We disclose properties…
