Magnetic field effects on two-leg Heisenberg antiferromagnetic ladders: Thermodynamic properties
Xiaoqun Wang, Lu Yu
Using the recently developed transfer-matrix renormalization group method, we have studied the thermodynamic properties of two-leg antiferromagnetic ladders in the magnetic field.…

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…
