Abstract: F19.00011 : Insulating states from increased kinetic energy: counterintuitive physics in the basic model of organic conductors and superconductors*
2:03 PM–2:15 PM
(DQMP, University of Geneva)
U-V model can exhibit very rich and complicated physics, which are a challenge to treat reliably. In the presented work, we show that the U-V model can give rise to surprising physics in which an insulating state emerges from increased transverse kinetic energy, by combining large-scale DMRG results with analytic RG of bosonized models of the 2-leg U-V Hubbard ladder.
