Universe as an oscillator

We apply the idea of using a matter-time gauge in quantum gravity to quantum cosmology. For a Friedmann-Lemaître-Robertson-Walker (FLRW) universe with dust and a cosmological constant ?, we show that the dynamics maps exactly to the simple harmonic oscillator in the dust-time gauge. For ?>0 the o...

Zusammenfassung:	We apply the idea of using a matter-time gauge in quantum gravity to quantum cosmology. For a Friedmann-Lemaître-Robertson-Walker (FLRW) universe with dust and a cosmological constant ?, we show that the dynamics maps exactly to the simple harmonic oscillator in the dust-time gauge. For ?>0 the oscillator frequency is imaginary, for ?
