Exciton-polariton emission from organic semiconductor optical waveguides
Exciton-polariton emission organic semiconductor optical waveguides
2011/8/17
Abstract: We photo-excite slab polymer waveguides doped with J-aggregating dye molecules and measure the leaky emission from strongly coupled waveguide exciton polariton modes at room temperature. We ...
Effects of s,p - d and s - p exchange interactions probed by exciton magnetospectroscopy in (Ga,Mn)N
exchange interactions exciton magnetospectroscopy
2010/11/25
Near band-gap photoluminescence and reflectivity in magnetic field are employed to determine the exchange-induced splitting of free exciton states in paramagnetic wurtzite Ga1−xMnxN, x . 1%,grow...
Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions
Possible realization ring-only exchange interactions
2010/11/17
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a K1
term acts on 1×1 plaquettes and a K2 term acts on 1×2 and 2×1 plaquettes, with a goal of realizing a no...
Coherence and Optical Emission from Bilayer Exciton Condensates
Coherence Optical Emission Bilayer Exciton Condensates
2010/11/23
Experiments aimed at demonstrating Bose-Einstein condensation of excitons in two types of experiments with bilayer structures (coupled quantum wells) are reviewed,with an emphasis on the basic e ects....
Repulsively-bound exciton-biexciton states in high-spin fermions in optical lattices
Repulsively-bound exciton-biexciton states optical lattices
2010/11/17
We show that the interplay between spin-changing collisions and quadratic Zeeman coupling
provides a novel mechanism for the formation of repulsively bound composites in high-spin fermions,which we i...
Exciton-phonon information flow in the energy transfer process of photosynthetic complexes
Exciton-phonon information flow energy transfer photosynthetic complexes
2010/11/18
Non-Markovian and non-equilibrium phonon effects are believed to be key ingredients in the energy transfer in photosynthetic complexes, especially in complexes which exhibit a regime of intermediate ...
Exciton-Plasmon Interactions in Individual Carbon Nanotubes
Carbon nanotubes Near-field effects Excitons Plasmons
2010/11/18
We use the macroscopic quantum electrodynamics approach suitable for absorbing and dispersing media to study the properties and role of collective surface excitations — excitons and plasmons — in sing...
Tunable exciton-phonon interactions in an optical lattice of polar molecules
Tunable exciton-phonon interactions optical lattice polar molecules
2010/11/11
We show that an ensemble of polar molecules trapped in an optical lattice can be considered as a controllable open quantum system. The coupling between collective rotational excitations and the center...
Coherent optical writing and reading of the exciton spin state in single quantum dots
Coherent optical writing reading exciton spin state single quantum dots
2010/10/21
We demonstrate a one to one correspondence between the polarization state of a light pulse tuned to excitonic resonances of single semiconductor quantum dots and the spin state of the exciton that it ...
Quantum dot Rabi rotations beyond the weak exciton-phonon coupling regime
Quantum dot Rabi rotations weak exciton-phonon coupling regime
2010/10/21
We study the excitonic dynamics of a driven quantum dot under the influence of a phonon
environment, going beyond the weak exciton-phonon coupling approximation. By combining the
polaron transform a...
