Quantum-noise quenching in atomic tweezers
, 2011 The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine state in which the atoms form a condensate to another stable state, in which ...

Hyperphosphorescent OLEDs: Harnessing the Power of MR‐TADF Terminal Emitters
Advanced Optical Materials, EarlyView.Hyperphosphorescent organic light‐emitting diodes (HP‐OLEDs) use phosphorescent sensitizers with multiresonant thermally activated delayed fluorescence terminal emitters. HP‐OLEDs show efficient, narrowband electroluminescence and moderate efficiency roll‐off.

Real-time optical micro-manipulation using optimized holograms generated on the GPU
, 2010 Holographic optical tweezers allow the three dimensional, dynamic, multipoint manipulation of micron sized dielectric objects. Exploiting the massive parallel architecture of modern GPUs we can generate highly optimized holograms at video frame rate ...

Size Effect on Photothermal Heating Ability of Gold Bipyramids
Advanced Optical Materials, EarlyView.Gold bipyramids with identical spectral characteristics exhibits opposite volume‐dependent photo‐thermal heating at single‐particle versus collective scales. The thermal energy can be used to generate mechanical work by powering Stirling engine. Abstract Gold nanoparticles (AuNPs) exhibit photothermal properties that are fundamental to biomedical and ...

Bandgap Tuning of β‐(AlxGa1‐x)2O3 Nanosheets via Liquid Metal Interface Engineering
Advanced Optical Materials, EarlyView.Ultrathin β‐(AlxGa1‐x)2O3 nanosheets with controlled composition are synthesized via low‐temperature squeeze‐printing of Al─Ga liquid alloys. Aluminium preferentially migrates to the surface of the liquid alloy, forming Al‐rich oxide layers with tunable bandgaps up to 6.4 eV. This compositionally precise approach enables the fabrication of 2D ultrawide‐

Quantum Zeno dynamics of a field in a cavity
, 2012 We analyze the quantum Zeno dynamics that takes place when a field stored in a cavity undergoes frequent interactions with atoms. We show that repeated measurements or unitary operations performed on the atoms probing the field state confine the ...

Nanoimprinting of Mesoporous Titania: Direct Patterning and Refractive Index Control in the Visible
Advanced Optical Materials, EarlyView.Nanoimprinted mesoporous TiO₂ (pTiO₂) films are demonstrated as high‐resolution optical materials with tunable porosity, refractive index, and mechanical response. Sub‐micron patterning of planar optics is shown alongside a refractive index contrast Δn ≈0.7.
