The pseudogap region of the phase diagram is an important unsolved puzzle in the field of hightransition-temperature (Tc) superconductivity, characterized by anomalous physical properties below a certain temperature, T*[1].

The strongly interacting conduction electrons can be accurately represented as a gas of weakly interacting electron-like excitations.

Hidden degrees of freedom in aperiodic crystals.

This work is part of a theoretical project which aims to unravel the mechanism at work in the high temperature cuprate superconductors.
