New Insights about Quantum Criticality in TGD Framework

Matti Pitkänen


Quantum criticality (QC) is one of the basic ideas of TGD. Zero energy ontology (ZEO) is second key notion and leads to a theory of consciousness as a formulation of quantum measurement theory making observer part of the quantum system in terms of notion of self-identified as a generalized Zeno effect or analog for a sequence of weak measurements, thus, solving the basic paradox of standard quantum measurement theory, which one usually tries to avoid by introducing some "interpretation". ZEO allows one to see quantum theory as "square root" of thermodynamics. It is interesting to apply this vision in the case of quantum criticality to gain additional insights about its meaning.
