PIRSA:18110081  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Chiral spin liquid phase of the triangular lattice Hubbard model: evidence from iDMRG in a mixed real- and momentum-space basis
Speaker(s): Aaron Szasz
Abstract: Experiments on organic crystals whose structure is well-described by the two-dimensional triangular lattice have found a lack of magnetic ordering down to the lowest accessible temperatures, indicative of a quantum spin liquid phase; however, the precise nature of this phase remains an open question... read more
