Classical-quantum gravity as quantum gravity in disguise
Masahiro Hotta, Sebastian Murk, Daniel R. Terno
Whether gravity must be quantized remains one of the biggest open problems in fundamental physics. Classical-quantum hybrid theories have recently attracted attention as a possible…

Probability vector representation of the Schrödinger equation and Leggett-Garg-type experiments
Masahiro Hotta, Sebastian Murk
Leggett-Garg inequalities place bounds on the temporal correlations of a system based on the principles of macroscopic realism and noninvasive measurability. Thei…
