Rolling Waves with Non-Paraxial Phonon Spins
Peng Zhang, Christian Kern, Sijie Sun +2
We demonstrate a new class of elastic waves in the bulk: When longitudinal and transverse components propagate at the same speed, rolling waves with a spin that is not parallel to…
Tracking Brownian motion in three dimensions and characterization of individual nanoparticles using a fiber-based high-finesse microcavity
Larissa Kohler, Matthias Mader, Christian Kern +2
The dynamics of nanosystems in solution contain a wealth of information with relevance for diverse fields ranging from materials science to biology and biomedical applications. Whe…
Tight Bounds on the Effective Complex Permittivity of Isotropic Composites and Related Problems
Christian Kern, Owen D. Miller, Graeme W. Milton
Almost four decades ago, Bergman and Milton independently showed that the isotropic effective electric permittivity of a two-phase composite material with a given volume fraction i…
Theory of the Hall effect in three-dimensional metamaterials
Christian Kern, Graeme W Milton, Muamer Kadic +1
We apply homogenization theory to calculate the effective electric conductivity and Hall coefficient tensor of passive three-dimensionally periodic metamaterials subject to a weak…
Parallel Hall effect from 3D single-component metamaterials
Christian Kern, Muamer Kadic, Martin Wegener
We propose a class of three-dimensional metamaterial architectures composed of a single doped semiconductor (e.g., n-Si) in air or vacuum that lead to unusual effective behavior of…
Hall-effect sign-inversion in a realizable 3D metamaterial
Muamer Kadic, Robert Schittny, Tiemo Bückmann +2
In 2009, Briane and Milton proved mathematically the existence of three-dimensional isotropic metamaterials with a classical Hall coefficient which is negative with respect to that…
