Critical behavior of the S=3/2 antiferromagnetic Heisenberg chain
K. Hallberg, X. Q. G. Wang, P. Horsch +1
Using the density-matrix renormalization-group technique we study the long-wavelength properties of the spin S=3/2 nearest-neighbor Heisenberg chain. We obtain an accurate value fo…

Superconducting pairing of spin polarons in the t-J model
N. M. Plakida, V. S. Oudovenko, P. Horsch +1
The pairing of quasiparticles in a CuO plane is studied within a spin polaron formulation of the -- model. Our numerical solution of the Eliashberg equations unamb…
