Ground-state reference systems for expanding correlated fermions in one dimension
F. Heidrich-Meisner, M. Rigol, A. Muramatsu +2
We study the sudden expansion of strongly correlated fermions in a one-dimensional lattice, utilizing the time-dependent density-matrix renormalization group method. Our focus is o…
Pairing states of a polarized Fermi gas trapped in a one-dimensional optical lattice
A. E. Feiguin, F. Heidrich-Meisner
We study the properties of a one-dimensional (1D) gas of fermions trapped in a lattice by means of the density matrix renormalization group method, focusing on the case of unequal…
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…
Time-step targetting methods for real-time dynamics using DMRG
Adrian E. Feiguin, Steven R. White
We present a time-step targetting scheme to simulate real-time dynamics efficiently using the density matrix renormalization group (DMRG). The algorithm works on ladders and system…
Real time evolution using the density matrix renormalization group
Steven R. White, Adrian E. Feiguin
We describe an extension to the density matrix renormalization group method incorporating real time evolution into the algorithm. Its application to transport problems in systems o…
