Probing the pairing symmetry and pair charge stiffness of doped ladders
A. E. Feiguin, S. R. White, D. J. Scalapino +1
We perform the numerical equivalent of a phase sensitive experiment on doped ladders. We apply proximity effect fields with different complex phases at both ends of an open s…
Interacting anyons in topological quantum liquids: The golden chain
Adrian Feiguin, Simon Trebst, Andreas W. W. Ludwig +4
We discuss generalizations of quantum spin Hamiltonians using anyonic degrees of freedom. The simplest model for interacting anyons energetically favors neighboring anyons to fuse…
Universal emergence of the one-third plateau in the magnetization process of frustrated quantum spin chains
F. Heidrich-Meisner, I. A. Sergienko, A. E. Feiguin +1
We present a numerical study of the magnetization process of frustrated quantum spin-S chains with S=1, 3/2, 2 as well as the classical limit. Using the exact diagonalization and d…
Applying Adaptive Time-Dependent DMRG to Calculate the Conductance of Strongly Correlated Nanostructures
K. A. Al-Hassanieh, A. E. Feiguin, J. A. Riera +2
A procedure based on the recently developed ``adaptive'' time-dependent density-matrix-renormalization-group (DMRG) technique is presented to calculate the zero temperature conduct…
