Description
After introductory presentation of the underlying idea of varying constants cosmologies I will explain how this idea can lead to toy cyclic models of the parallel universes (the multiverse) with different evolution of the fundamental constants and same geometry using the condition that the total entropy of the system does not decrease. Then, I will describe how to use the second quantization method, which on the level of the Wheeler-deWitt quantum universe is known as third quantization procedure, in order to form quantum multiverse which is a quantum entangled system on the base of these classical models. I will show that the entanglement quantities (entropy, temperature) can be the measures of the “quantumness” of some classical regimes of the universe evolution and also the tools to observationally measure the multiverse signals. Finally, the issues related to generation of baryon asymmetry in the multiverse will be presented.
