Colloquium: Quantum Properties and Functionalities of Magnetic Skyrmions
Alexander P. Petrović, Christina Psaroudaki, Peter Fischer +2
Competing magnetic interactions may stabilize smooth magnetization textures that can be characterized by a topological winding number. Such textures, which are spatially localized…
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…
Magnetic excitations in the spin-1 anisotropic antiferromagnet
C. Psaroudaki, S. A. Zvyagin, J. Krzystek +3
The spin-1 anisotropic antiferromagnet NiCl_2-4SC(NH2)_2 exhibits a field-induced quantum phase transition that is formally analogous to Bose-Einstein condensation. Here we present…
