Maths HEP Lunchtime Seminars: 2D correlated fermions and exactly solvable systems
30 October 2009 13:00 in CM221
I discuss the problem of how to do reliably computation in two
dimensional (2D) lattice fermion models of Hubbard type and what exactly
solvable systems can possibly contribute to its solution. I recall how
the 1D Luttinger model, a well-known exactly solvable model, has
contributed to our understanding of 1D lattice fermion systems. I also
present a 2D analogue of this story.
