On the exact quantum scale invariance of three-dimensional reduced QED theories

Understand

An effective quantum field theory description of graphene in the ultra-relativistic regime is given by reduced QED aka.

• pseudo QED aka.
• mixed-dimensional QED.
• It has been speculated in the literature that reduced QED constitutes an example of a specific class of hard-to-find theories: an interacting CFT in more than two dimensions.
