Checkerboard patterns in the t-J model
Steven R. White, D. J. Scalapino
Using the density matrix renormalization group, we study the possibility of real space checkerboard patterns arising as the ground states of the t-J model. We find that checkerboar…
Spin-liquid versus dimerized ground states in a frustrated Heisenberg antiferromagnet
Luca Capriotti, Douglas J. Scalapino, Steven R. White
We present a Density Matrix Renormalization Group (DMRG) study of the ground-state properties of spin-1/2 frustrated Heisenberg -leg ladders (with up to 8). Fo…
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…
Resonant magnetic mode in superconducting 2-leg ladders
D. Poilblanc, E. Orignac, S. R. White +1
The spin dynamics of a doped 2-leg spin ladder is investigated by numerical techniques. We show that a hole pair-magnon boundstate evolves at finite hole doping into a sharp magnet…
Edge States in Doped Antiferromagnetic Nano-Structures
A. L. Chernyshev, A. H. Castro Neto, S. R. White
We study competition between different phases in a strongly correlated nano-structure with an edge. Making use of the self-consistent Green's function and density matrix renormaliz…
