Their topics include new nanomaterials and devices, plasmon polaritons, principles of nanostructures and nanomaterials, instruments for nanoscale electronics, electronic devices based on carbon nanotubes and other nanostructures, optoelectronic nanodevices, and molecular and biological nanodevices.
Real-time monitoring of changes in the resonance properties of the crystal allows the label-free determination of interaction affinities and kinetics, as is the case for optical biosensors that exploit interfacial evanescence and/or surface polaritons (42).
These waves, which can be thought of as "virtual particles" known as surface plasmon polaritons (SPPs), then follow the curved trajectory of the Airy beams.
The approach taken is two-pronged: On the one hand, we devise versatile and practical platforms for dynamical simulators making use of systems of ultra-cold atoms in optical lattices and the continuum, as well as cavity polaritons.
His team uses a thin strip of gallium nitride along with mirrors and electrodes to preserve the short-lived polaritons and emit a weak beam of ultraviolet light.
Among specific topics are relativistic high-order harmonic generation, feedback-driven adiabatic quantum dynamics, multiple interactions in multilayered structures of nonlinear materials, a computer algebra study of structural and symmetrical properties of discrete dynamical systems, slow light and phase transition in the array of atomic polaritons, and two-dimensional confined terahertz wave propagation in a gap plasmon waveguide formed by two cylindrical surfaces.
Most of the intrinsic resonant behavior in the microwave through millimeter frequency bands are due to cooperative ferromagnetic and ferrite spin-related resonances, antiferromagnetic resonances, microwave atomic transitions, plasmons and plasmon-like resonances, and polaritons at metal-dielectric interfaces.
Topics include optical microscopy and spectroscopy of single molecules, optical properties of single conjugated polymer chains (polydiacetylenes), morphology-correlated photophysics in organic semiconductor thin films by confocal laser microscopy and spectroscopy, spectroscopy of long-lived photoexcitations in pi- conjugated systems, charge transport in disordered organic semiconductors, probing organic semiconductors with terahertz pulses, macroscopic polarization and exciton properties for strong exciton polaritons in anisotropic crystals, sub-5 fs spectroscopy of polydiacetylene, and ultrafast optoelectronic probing of excited states in low-dimensional carbon-based pi-conjugated materials.
Objective: Due to the promising potential of evanescent optical waves and surface plasmon polaritons to successfully merge current photonic and electronic technology on the nanoscale, they are generally envisioned as the information carriers of the future.
Excitons then interact with photons to form exotic light-matter hybrids called polaritons, which in turn decay and release photons with the same energy and direction.
