Non-equilibrium transport through a point contact in the non-Abelian quantum Hall state
Adrian Feiguin, Paul Fendley, Matthew P. A. Fisher +1
We analyze charge- quasiparticle tunneling between the edges of a point contact in a non-Abelian model of the quantum Hall state. We map this problem to resonant tunne…
Spectral properties of a partially spin-polarized one-dimensional Hubbard/Luttinger superfluid
Adrian E. Feiguin, David A. Huse
We calculate the excitation spectra of a spin-polarized Hubbard chain away from half-filling, using a high-precision momentum-resolved time-dependent Density Matrix Renormalization…
Pair correlations of a spin-imbalanced Fermi gas on two-leg ladders
A. E. Feiguin, F. Heidrich-Meisner
We study the pair correlations of a spin-imbalanced two-leg ladder with attractive interactions, using the density matrix renormalization group method (DMRG). We identify regions i…
Transport properties and Kondo correlations in nanostructures: the time-dependent DMRG method applied to quantum dots coupled to Wilson chains
Luis G. G. V. Dias da Silva, F. Heidrich-Meisner, A. E. Feiguin +4
We apply the adaptive time-dependent Density Matrix Renormalization Group method (tDMRG) to the study of transport properties of quantum-dot systems connected to metallic leads. Fi…
Excitons in the One-Dimensional Hubbard Model: a Real-Time Study
K. A. Al-Hassanieh, F. A. Reboredo, A. E. Feiguin +2
We study the real-time dynamics of a pair hole/doubly-occupied-site, namely a holon and a doublon, in a 1D Hubbard insulator with on-site and nearest-neighbor Coulomb repulsion. Ou…
Spin polarization of the quantum Hall state
A. E. Feiguin, E. Rezayi, Kun Yang +2
We report on results of numerical studies of the spin polarization of the half filled second Landau level, which corresponds to the fractional quantum Hall state at filling factor…
