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…

Low-frequency spin dynamics in the orthorombic phase of La_2CuO_4
J. Chovan, N. Papanicolaou
An effective field theory is derived that describes the low-frequency spin dynamics in the low-temperature orthorombic phase of La_2CuO_4. Restricted to a single CuO_2 layer the ef…

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…
