Effective de Sitter space, quantum behaviour and large-scale spectral dimension (3+1)
Abstract De Sitter space-time, essentially our own universe, is plagued by problems at the quantum level. Here we propose that Lorentzian de Sitter space-time is not fundamental but constitutes only an effective description of a more fundamental quantum gravity ground state. This cosmological ground...
