Criticality & Dark Matter

Abstract

Quantum criticality is one of the corner stone assumptions of TGD. The value of Kahler coupling strength fixes quantum TGD and is analogous to critical temperature. TGD Universe would be quantum critical. What does this mean is however far from obvious and I have pondered the notion repeatedly both from the point of view of mathematical description and phenomenology. Superfluids exhibit rather mysterious looking effects such as fountain effect and what looks like quantum coherence of superfluid containers which should be classically isolated. These findings serve as a motivation for the proposal that genuine superfluid portion of superfluid corresponds to a large h_eff phase near criticality at least and that also in other phase transition like phenomena a phase transition to dark phase occurs near the vicinity.
