Gauged fermionic matrix quantum mechanics

Understand

We consider the gauged free fermionic matrix model, for a single fermionic matrix.

• In the large $N$ limit this system describes a $c=1/2$ chiral fermion in $1+1$ dimensions.
• The Gauss' law constraint implies that to obtain a physical state, indices of the fermionic matrices must be fully contracted, to form a singlet.
• There are two ways in which this can be achieved: one can consider a trace basis formed from products of traces of fermionic matrices or one can consider a Schur function basis, labeled by Young diagrams.
