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…

Field induced phase transitions in the helimagnet Ba2CuGe2O7
J. Chovan, M. Marder, N. Papanicolaou
We present a theoretical study of the two-dimensional spiral antiferromagnet Ba2CuGe2O7 in the presence of an external magnetic field. We employ a suitable nonlinear sigma model to…
