Dagotto<br/>We study the real-time dynamics of a hole and doubly occupied site pair, namely, a holon and a doublon, in a 1D Hubbard insulator with on-site and nearest-neighbor Coulomb repulsion. Our analysis shows that the pair is long-lived and the expected decay mechanism to underlying spin excitations is ac...<br/>[Phys. Rev. Lett. 100, 166403] Published Fri Apr 25, 2008 Phys. Rev.

D. Stewart, Jr., A. Yin, J. M. Xu, and J. M. Valles, Jr.<br/>We have observed multiple magnetic field driven superconductor-to-insulator transitions (SIT) in amorphous Bi films perforated with a nanohoneycomb (NHC) array of holes. The period of the magnetoresistance, H=H_{M}=h∕2eS, where S is the area of a unit cell of holes, indicates that the field driven ...<br/>[Phys. Rev. B 77, 140501] Published Tue Apr 01, 2008 Phys.
