Detectability of avoided crossings in black hole ringdowns
Hayato Imafuku, Naritaka Oshita, Hiroki Takeda
Quasinormal modes (QNMs) of black holes can exhibit avoided crossings (ACs), in which specific QNM frequencies approach each other while their amplitudes are enhanced and acquire n…

Emergence of Non-Markovian Classical-Quantum Dynamics from Decoherence
Shogo Tomizuka, Hiroki Takeda
The quantum nature of gravity remains experimentally unverified, despite recent proposals to probe it using tabletop experiments such as gravity-mediated entanglement schemes. In p…
