26. Active magnetoplasmonics for nanoscale distances sensing
Sammanfattning : Magnetoplasmonics is an emerging field within nano-photonics that operates with the combination of propagating or localized surface plasmons and magnetism. Active and adaptive magnetoplasmonic components that are capable of controlling light on the nanoscale with external weak magnetic fields are envisioned to push the development of integrated photonic circuits, high-density data storage, or the advanced schemes for bio- and chemo-sensing.

27. Electron Transport and Collective Modes in Fermi and non-Fermi Liquids
Sammanfattning : Today’s novel materials can display many interesting phases. Two-dimensional materials with strong electron-electron interactions allow the electrons to enter a hydrodynamic regime at intermediate temperatures. LÄS MER
28. Theoretical studies of collective electronic excitations in low-dimensional structures
Sammanfattning : During the past decade, nanoplasmonics and nanophotonicshas emerged as a new branch of nanosciences with many novelapplications. Central in this development is the localized surface plasmon resonance (LSPR) tunable by the sizes and shapes at nanometer scale. LÄS MER
29. Designer magnetoplasmonics for adaptive nano-optics
Sammanfattning : Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to manipulate light via the local EM field shaping and enhancement.
