Quasi-bound states and late-time evolution of a massive fermion around a Reissner-Nordström black hole
Guang-Shang Chen, Cheng-Bo Yang, Shou-Shan Bao +2
A massive fermion around a charged black hole provides a gravitational analogue of atomic bound states and their relaxation. In this work, we study this system by formulating the r…
Aziz and Howl's Gravity-Induced Entanglement Channel is Essentially Classical Mechanics
Hanyu Xue, Ziqian Tang, Chen Yang +3
Aziz and Howl argued that a classical gravitational field can generate quantum entanglement through a quantum-field-theoretic channel mediated by virtual matter propagation. Howeve…
Matter-Mediated Entanglement in Classical Gravity: Suppression by Binding Potentials and Localization
Ziqian Tang, Chen Yang, Zizhao Han +3
Aziz and Howl [Nature 646 (2025)] argue that two spatially separated masses can become entangled even when gravity is treated as a classical field, by invoking higher-order "virtua…
Quantum-classical gravity distinction in reservoir-engineered massive quantum system
Ziqian Tang, Zizhao Han, Zikuan Kan +4
Massive quantum systems have emerged as compelling tabletop interface-systems for testing the quantum nature of gravity. However, conventional schemes that focus on directly using…
Revisiting the fermionic quasi-bound states around Schwarzschild black holes with improved analytic spectrum
Guang-Shang Chen, Cheng-Bo Yang, Shou-Shan Bao +2
Black holes have long served as a testing ground for probing theories of gravity and quantum mechanics. Notably, fundamental fields in the neighborhood of black holes exhibit rich…
