Physics - The Anthony J Leggett Institute for Condensed Matter Theory Seminar

The Mott problem stands as a grand challenge largely because its solution is at the heart of high-temperature superconductivity in the cuprates.   It is unfortunate that such materials are largely 2-dimensional and the only exact solutions are restricted to d=1 with Bethe ansatz and infinite dimensions.

I will present  a method valid in any dimension that recovers the Bethe ansatz results  in $d=1$ and the $d=\infty$ solutions as well.  At the heart of the method is the breaking of an overlooked $Z_2$ symmetry of Fermi liquids .  I will present benchmarks for the method in d=1 and  compare with "accepted'' results in d=2, where no exact results are known.
