Spatially‐Resolved Coherence of Organic Molecular Spins at Room‐Temperature
Advanced Functional Materials, EarlyView.Molecular spin qubits are emerging as a promising quantum sensing technology. This paper studies the variation in coherence and sensitivity in both crystalline and thin‐film samples by combining microscopy and room temperature optically detected coherent control.

Coherent two photon excitation within an extended cloud of Rubidium 85 for the purposes of atomic interferometry and cooling [PDF]
, 2011 Cold atom samples, at temperatures of the order 100 µK, are useful for a wide reaching array of new and exciting technological and scientific endeavours. Atoms are conventionally cooled by Doppler cooling, which relies on the continuous absorption and re-

Laser Cooling of an Optomechanical Crystal Resonator to Its Quantum Ground State of Motion [PDF]
, 2012 Quantum mechanics continues to intrigue us with bizarre predictions that seemingly run counter to our everyday classical intuition. Superposition, zero-point motion, entanglement, and inescapable bounds on measurement precision are just a few purely ...

Compact ultracold electron source based on a grating magneto-optical trap
Physical Review Accelerators and Beams, 2019 The ultrafast and ultracold electron source, based on near-threshold photoionization of a laser-cooled and trapped atomic gas, offers a unique combination of low transverse beam emittance and high bunch charge. Its use is however still limited because of

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame
Advanced Functional Materials, EarlyView.High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

Advanced Functional Materials, EarlyView.Enhancing crystallinity through thermal annealing leads to amplifying the chiroptical activity of TiO2 nanohelices (NHs) fabricated by glancing angle deposition, ascribed to the suppression of charge trapping. The enhanced chiroptical activity can be converted into pronounced dissymmetric photocatalytic kinetics of circularly polarized photocatalysis ...

A chirped, pulsed laser system and magneto-optical trap for rubidium [PDF]
, 2009 This thesis covers the construction and characterisation of a magneto-optical trap (MOT) for 85Rb from the very beginning. It details both the optical and mechanical aspects from laser diode assembly, tuning and stabilisation to the preparation and ...
