Space group symmetry fractionalization in a chiral kagome Heisenberg antiferromagnet
Michael P. Zaletel, Zhenyue Zhu, Yuan-Ming Lu +2
The anyonic excitations of a spin-liquid can feature fractional quantum numbers under space-group symmetries. Detecting these fractional quantum numbers, which are analogs of the f…
Compression of Correlation Matrices and an Efficient Method for Forming Matrix Product States of Fermionic Gaussian States
Matthew T. Fishman, Steven R. White
Here we present an efficient and numerically stable procedure for compressing a correlation matrix into a set of local unitary single-particle gates, which leads to a very efficien…
One Dimensional Mimicking of Electronic Structure: The Case for Exponentials
Thomas E. Baker, E. Miles Stoudenmire, Lucas O. Wagner +2
An exponential interaction is constructed so that one-dimensional atoms and chains of atoms mimic the general behavior of their three-dimensional counterparts. Relative to the more…
Doping Asymmetry of a 3-orbital CuO Hubbard Model
Steven R. White, D. J. Scalapino
While both the hole and electron doped cuprates can exhibit -wave superconductivity, the local distribution of the doped carriers is known to be significantly differen…
One hole in the two-leg t-J ladder and adiabatic continuity to the non-interacting limit
S. R. White, D. J. Scalapino, S. A. Kivelson
We have carried out density-matrix-renormalization group (DMRG) calculations for the problem of one doped hole in a two-leg ladder. Recent studies have concluded that exotic…
Spin liquid phase of the Heisenberg model on the triangular lattice
Zhenyue Zhu, Steven R. White
We study the Heisenberg model on the triangular lattice with nearest neighbor interaction and next nearest neighbor interaction with the density matrix renormal…
