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…
Magnetization in Molecular Iron Rings
B. Normand, X. Wang, X. Zotos +1
The organometallic ring molecules Fe_6 and Fe_10 are leading examples of a class of nanoscopic molecular magnets, which have been of intense recent interest both for their intrinsi…
Reactive Hall response
X. Zotos, F. Naef, M. Long +1
The zero temperature Hall constant R_H, described by reactive (nondissipative) conductivities, is analyzed within linear response theory. It is found that in a certain limit, R_H i…
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…
