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…
Quantum criticality and mixed-state entanglement in holographic superconductor--insulator transitions
Zhe Yang, Fang-Jing Cheng, Guoyang Fu +3
We study quantum criticality in a holographic Einstein--Maxwell--Dilaton--Axion (EMDA) p-wave superconductor exhibiting a superconductor--insulator transition (SIT). By tracking th…
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…
Imprints of quantum gravity effects on gravitational waves: a comparative study using extreme mass-ratio inspirals
Ruo-Ting Chen, Guoyang Fu, Dan Zhang +1
Within a generally covariant Hamiltonian framework of loop quantum gravity (LQG), two black hole models parameterized by a quantum correction have recently been constructed. U…
Echoes from the Minkowski-core spacetime
Dan Zhang, Qin Tan, Guoyang Fu +3
In this study, we construct a class of horizonless exotic compact objects (ECOs) with Minkowski core, classifying them as either photon sphere ECOs (PS ECOs) or photon sphere lacki…
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…
