Photon Spheres and Shadows of Covariant Loop Quantum Black Holes in the general -scheme

Yu Han, Meng Liu, Yongzhuang Li

We investigate black hole shadows and photon sphere properties for two families of covariant quantum-corrected black-hole metrics (hereafter called BH-I and BH-II) formulated withi…

Particle motions and gravitational waveforms in rotating black hole spacetimes of loop quantum gravity

Yang Yang, Yu-Xuan Bai, Yong-Zhuang Li +1

We study the influence of the loop quantum gravity (LQG) holonomy-correction parameter on black hole horizon structure, timelike geodesic motion, and gravitational wave emissio…

Quantisation ambiguities and the effective dynamics of scalar-tensor theories in loop quantum cosmology

Yu Han

The Hamiltonian constraint of scalar-tensor theories in the Jordan frame is quantised using three quantisation prescriptions in loop quantum cosmology, from which we obtain three d…

Nonclassical cosmological dynamics in the low-energy limit of loop quantum scalar-tensor theory

Yu Han

In previous work, we showed that in loop quantum cosmology of scalar-tensor theory (STT) with the holonomy correction the background equations of motion in the Jordan frame have tw…

Loop quantum cosmological dynamics of scalar-tensor theory in the Jordan frame

Yu Han

The effective dynamics of scalar-tensor theory (STT) in the Jordan frame is studied in the context of loop quantum cosmology with holonomy corrections. After deriving the effective…

Testing the weak equivalence principle with the binary neutron star merger GW170817: the gravitational contribution of the host galaxy

Lulu Yao, Zonghua Zhao, Yu Han +3

The successful detection of the binary neutron star (BNS) merger GW170817 and its electromagnetic (EM) counterparts has provided an opportunity to explore the joint effect of the h…
