Effective S=1/2 description of the S=1 chain with strong easy plane anisotropy
C. Psaroudaki, J. Herbrych, J. Karadamoglou +3
We present a study of the one-dimensional S=1 antiferromagnetic spin chain with large easy plane anisotropy, with special emphasis on field-induced quantum phase transitions. Tempe…
Diffusive transport in spin-1 chains at high temperatures
J. Karadamoglou, X. Zotos
We present a numerical study on the spin and thermal conductivities of the spin-1 Heisenberg chain in the high temperature limit, in particular of the Drude weight contribution and…
Nonlinear excitations in CsNiF3 in magnetic fields perpendicular to the easy plane
M. Orendac, A. Orendacova, E. Cizmar +8
Experimental and numerical studies of the magnetic field dependence of the specific heat and magnetization of single crystals of CsNiF3 have been performed at 2.4 K, 2.9 K, and 4.2…
Finite Temperature Dynamical Correlations using the Microcanonical Ensemble and the Lanczos Algorithm
M. W. Long, P. Prelovsek, S. El Shawish +2
We show how to generalise the zero temperature Lanczos method for calculating dynamical correlation functions to finite temperatures. The key is the microcanonical ensemble, which…
Magnon dispersion and thermodynamics in CsNiF_3
J. Karadamoglou, N. Papanicolaou, X. Wang +1
We present an accurate transfer matrix renormalization group calculation of the thermodynamics in a quantum spin-1 planar ferromagnetic chain. We also calculate the field dependenc…
Thermodynamics of the spin-flop transition in a quantum XYZ chain
X. Wang, X. Zotos, J. Karadamoglou +1
A special limit of an antiferromagnetic XYZ chain was recently shown to exhibit interesting bulk as well as surface spin-flop transitions at T=0. Here we provide a complete calcula…
