Non-Hermitian quantum physics in cerebral dynamics: Preliminary results
We propose that cerebral dynamics can be considered as a non-Hermitian quantum system which during a short interval of the cardiac cycle has real eigenvalues. We show that driving the system into PT symmetry is only possible with the help of the active matter changing from a laminar flow into a Ceilidh dance-like flow. During this change, the flow experiences a transition from broken to unbroken PT symmetries which results in a topological phase. The topological phase is then imparted onto the topological defects which are an essential part of this Ceilidh dance flow. This so-called topological braid could be the basis of topological computing in the brain. Our recent experimental findings in conscious humans have shown that the predicted PT symmetry changes may exist. This is important because it is also related to consciousness underpinning the computational aspect of the phenomenon.
Cardiac pulsation evokes long-range quantum coherence in the conscious brain
We report long-range zero quantum coherence (ZQC) in 40 volunteers, which were repeatedly evoked by the incoming blood pulse. They were observable for periods of 150-400ms if and only if the volunteer was awake. This direct link to blood pulse and wakefulness suggests that the underlying mechanism of the ZQC is a necessity for consciousness. We show that the ZQC generation by the cardiac pulse is inconsistent with Landau's concept of symmetry-breaking matter. However, the ZQC is compatible with the assumption that its underlying mechanism is a non-local topological entanglement arising from a topological ordered phase transition. Then, topological defects, which exist in biology in numerous ways, can be linked to computing and with that to consciousness.
