Adiabatic entanglement transport in Rydberg aggregates

, 2011
We consider the interplay between excitonic and atomic motion in a regular, flexible chain of Rydberg atoms, extending our recent results on entanglement transport in Rydberg chains [W\"uster et al., Phys.Rev.Lett 105 053004 (2010)].

Highly Selective Terahertz Bandpass Filters Based on Trapped Mode Excitation [PDF]

, 2009
We present two types of metamaterial-based spectral bandpass filters for the terahertz (THz) frequency range. The metamaterials are specifically designed to operate for waves at normal incidence and to be independent of the field polarization.

Controlling flexible rotor vibrations using parametric excitation

Journal of Physics: Conference Series, 2009
This paper presents both theoretical and experimental studies of an active vibration controller for vibration in a flexible rotor system. The paper shows that the vibration amplitude can be modified by introducing an axial parametric excitation. The perturbation method of multiple scales is used to solve the equations of motion.
