Universal Casimir attraction between filaments at the cell scale

The electromagnetic Casimir interaction between dielectric objects immersed in salted water includes a universal contribution that is not screened by the solvent and therefore long-ranged. Here, we study the geometry of two parallel dielectric cylinders. W ...

Individual Barkhausen pulses of ferroelastic nanodomains

Dragan Damjanovic, Vasiliki Tileli, Reinis Ignatans

Ferroelectric materials, upon electric field biasing, display polarization discontinuities known as Barkhausen jumps, a subclass of a more general phenomenon known as crackling noise. Herein, we follow at the nanoscale the motion of 90 degree needle domain ...

Identification of microscopic domain wall motion from temperature dependence of nonlinear dielectric response

Tomas Sluka, Pavel Mokry

It is known that the permittivity of ferroelectric polydomain films and single crystals in weak electric fields is strongly enhanced by the reversible movement of pinned domain walls. Two mechanisms of the movement exist: first, the bending of free segment ...

Nonlinear dynamics of polar regions in paraelectric phase of (Ba1-x,Srx)TiO3 ceramics

Dragan Damjanovic

The dynamic dielectric nonlinearity of barium strontium titanate (Ba1-x, Sr-x) TiO3 ceramics is investigated in their paraelectric phase. With the goal to contribute to the identification of the mechanisms that govern the dielectric nonlinearity in this fa ...

Identification of defect distribution at ferroelectric domain walls from evolution of nonlinear dielectric response during the aging process

Tomas Sluka, Pavel Mokry

The motion of ferroelectric domain walls greatly contributes to the macroscopic dielectric and piezoelectric response of ferroelectric materials. The domain-wall motion through the ferroelectric material is, however, hindered by pinning on crystal defects, ...

Towards Flexible, Scalable and Low Loss Non-reciprocal System in Silicon Photonics

Christophe Marcel Georges Galland, Yang Liu

A silicon photonic non-reciprocal isolator/circulator system with time-dependent permittivity tensor is demonstrated. In addition to being broadband and low loss, the architecture is scalable to achieve high extinction ratio with reconfigurable isolation p ...

Unusual dielectric behavior and domain structure in rhombohedral phase of BaTiO3 single crystals

Nava Setter, Alexander Tagantsev, Dragan Damjanovic

It was noticed long time ago that the dielectric permittivity of BaTiO3 single crystals in the rhombohedral phase varies from observation to observation, but the microstructure mechanism behind this phenomenon remained unclear. We show that the variations ...

Integrated modelling of Ion Cyclotron Resonant Heating in toroidal system

Jonathan Graves, Wilfred Anthony Cooper, Stephan Brunner, Martin Jucker, Nicolas Mellet

An integrated model capable of self-consistent Ion Cyclotron Resonant Heating (ICRH) simulations has been developed. This model includes both full shaping and pressure effects, warm contributions to the dielectric tensor, pressure anisotropy and finite orb ...
