Description
It is argued that there is a novel type of energy related to the theta parameter in gauge theories. This energy has so-called ``non-dispersive nature" and can not be expressed in terms of any local propagating degrees of freedom. Instead, this energy is generated due to the presence of the topologically nontrivial sectors in gauge theories, and tunnelling events between them. The talk is based on 3 recent papers:
1. applications to cosmology (PRD 2015, arXiv:1505.05151),
2. proposal to study this novel type of energy in a tabletop experiment in Maxwell system (PRD 2016, arXiv:1512.00470)
3. New ideas for the axion search experiments sensitive to theta_{QED} (arXiv:1702.00012)
