Echoes and quasinormal modes for static loop quantum black bounces
Huajie Gong, Guoyang Fu, Shulan Li +3
We investigate scalar perturbations of the static loop quantum black bounce (LQBB) spacetime with multipole index , focusing on time-domain signals and fundamental quasinormal…
Quasinormal modes of a rotating loop quantum black hole
Zhongzhinan Dong, Shulan Li, Dan Zhang +1
We investigate the quasinormal modes of a massless scalar field on an effective rotating loop quantum black hole background, constructed from a covariant spherical model via an imp…
Assessing EMRI Detectability of the Rotating Quantum Oppenheimer-Snyder Black Hole
Dan Zhang, Shulan Li, Guoyang Fu +1
This letter presents an assessment of quantum gravity effects on extreme-mass-ratio inspirals (EMRIs) for the rotating quantum Oppenheimer-Snyder (qOS) black hole. Employing the ad…
Chaos as a Possible Probe for Scalar Hair in Horndeski Gravity
Yang Yu, Ruo-Ting Chen, Shulan Li +2
The detection of black hole scalar hair, a possible deviation from general relativity's "no-hair" theorem, requires sensitive probes beyond conventional methods. This study propose…
Non-singular cosmologies matching regular black holes
Shulan Li, Jian-Pin Wu, Xian-Hui Ge
We construct a new non-singular cosmological model matched to a Minkowski-core regular black hole by means of a modified Oppenheimer--Snyder framework. Its dynamics is studied in b…
Quasinormal modes of a charged loop quantum black hole
Li-Gang Zhu, Guoyang Fu, Shulan Li +2
This study presents a systematic investigation of quasinormal modes (QNMs) for probe fields-massless/massive scalar and Dirac fields-around a charged loop quantum gravity black hol…
