Electrically-driven single-photon sources based on colloidal quantum dots with near-optimal antibunching at room temperature

Nature Communications, 2017
Single-photon sources are one of the most basic devices for quantum optical experiments and applications. Here, Lin et al. present an electrically driven single-photon source based on solution-processed colloidal quantum dots with near-optimal ...

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

Advanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

Single-Shot Quantum Nondemolition Detection of Individual Itinerant Microwave Photons

Physical Review X, 2018
Single-photon detection is an essential component in many experiments in quantum optics, but it remains challenging in the microwave domain. We realize a quantum nondemolition detector for propagating microwave photons and characterize its performance ...

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, EarlyView.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Single-photon atomic cooling [PDF]

, 2009
textThis dissertation details the development and experimental implementation of single-photon atomic cooling. In this scheme atoms are transferred from a large-volume magnetic trap into a small-volume optical trap via a single spontaneous Raman ...

Entangled mechanical cat states via conditional single photon optomechanics

New Journal of Physics, 2013
We study single photon optomechanics conditioned on photon counting events. By selecting only detection events that occur long after a photon pulse arrives at the cavity, the optomechanical interaction time can be increased, allowing a large momentum ...

Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures

Advanced Functional Materials, EarlyView.
To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.

Integration of a single photon source with a fibre-compatible photonic waveguide

npj Quantum Information
The integration of a single photon source based on a solid-state emitter with a photonic structure remains challenging and specifically when it comes to be compatible with optical fibres.

Discovery of Energy‐Localized Trap States via Opto‐Electrical Spectroscopy in UWBG Perovskite La:SrSnO3 FETs

Advanced Functional Materials, EarlyView.
Combined UV–vis transmittance and wavelength‐dependent photo‐assisted DC I–V analyses reveal defect‐induced optical instability and a high density of deep donor‐like subgap traps in La‐doped SrSnO3. The resulting MOSFET achieves one of the highest on/off ratios reported for ABO3 perovskite devices, demonstrating the promise of stannate perovskites as ...
