Decoherence of quantum superpositions in near-extremal Reissner-Nordström black holes with quantum gravity corrections
Ran Li, Zhong-Xiao Man, Jin Wang
We study the quantum gravity corrected decoherence of quantum superpositions in the near-extremal Reissner-Nordström black holes. By employing the effective field theory approach,…

Note on the local calculation of decoherence of quantum superpositions in de Sitter spacetime
Ran Li
We study the decoherence effect of quantum superposition in de Sitter (dS) spacetime due to the presence of the cosmological horizon. Using the algebraic approach of quantum field…

Decoherence of quantum superpositions by Reissner-Nordström black holes
Ran Li
Recently, it was shown by Danielson-Satishchandran-Wald (DSW) that for the massive or charged body in a quantum spatial separated superposition state, the presence of a black hole…
