Direct observation of the discrete character of intrinsic localized modes in an antiferromagnet
Article Abstract:
The observation of countable localized excitations in an antiferromagnetic spin lattice by means of a nonlinear spectroscopic technique is presented. This observation capability permits the properties of individual intrinsic localized modes (ILMs) to be probed, and the disappearance of each ILM registers as a step in the time-dependent signal, with the surprising result the energy staircase of ILM excitations is uniquely defined.

Fresh breather
Article Abstract:
The study reports the sighting of a particularly elusive form of discrete breather that exists at the atomic scale in a magnetic solid. It used a novel nonlinear spectroscopic technique that enhances the signal produced by the discrete breathers and suppresses the linear spin-wave signal and enables to 'lock' a small number of discrete breathers to an external driving frequency.

Three-dimensional atomic-scale structure of size-selected gold nanoclusters
Article Abstract:
A new approach for the determination of the three-dimensional atomic-scale structure of the size-selected gold nanoclusters is discussed. The described method has been found to be helpful for various other ultrasmall metal cluster systems as well.
