There is a talk in the Harvard Physics Department tomorrow by Steven White,
the father of DMRG:
"The First Realistic Quantum Spin Liquids", Steven White, University of
California, Irvine(Jefferson 250.....Tea served in Jefferson 450 @ 3:30 pm)
Mar 7, 2011
4:15p - 5:15p
Description A quantum spin liquid is a solid whose atoms have magnetic
moments but,
because of quantum fluctuations, these moments fluctuate like a liquid
even at zero temperature. Two dimensional spin liquids have been suggested
as a way to produce high temperature superconductivity, and to build quantum
computers. Just as helium is the only element which is a liquid at zero
temperature, 2D spin liquids have been extremely difficult to find, despite
decades of effort, raising the question, do realistic spin liquids even
exist? Recently, spin liquids have been found both experimentally and in
numerical solutions of realistic models. I will give a broad overview of
spin liquids and then focus on our recent simulations of the Kagome lattice,
where we find a spin liquid ground state.
