(Obsolete: see following talk.)

Addendum:

- For the Hubbard model, we use
*t*= 1 and*U*= 5.

(Obsolete: see following talk.)

Erratum:

- Slide 8: The second bullet point should say something like ‘The Lagrangian is invariant under U(1) gauge transformations of
*ψ*and*A*.’^{μ}

Erratum:

- Slide 9: The scale of the
*x*-axis labels on the left column are half of what they should be (i.e. 0, 0.1, 0.2).
