The Design and Construction of a Rubidium Magneto-Optical Trap
A magneto-optical trap (MOT) cools atoms to microkelvin range temperatures by trapping atoms within perpendicular laser beams and varying magnetic fields [1]. A MOT uses opposing photon emission and absorption to reduce an atom’s speed, consequently reducing its temperature. By combining this with a magnetic field, the MOT works to trap an atom ... read more

Quantum-Optimized Reconstruction of Ketone Dynamics from Fabry-Pérot Optical Breath Measurements
Introduction: Diabetes management depends on measurements that are often invasive, intermittent, or expensive. Acetone in exhaled breath is linked to ketone metabolism and can be measured optically, but a breath spectrum is not itself a metabolic state: the clinically meaningful quantities—blood β-hydroxybutyrate (BHB), acetoacetate, acetone, and t... read more

Rb Optically Pumped Magnetometry
Deception can produce involuntary and measurable changes in cardiovascular response. For example, significant differences in heart rate have been found when comparing truthful and deceptive responses (Godert et al. 2001). Atomic magnetometers can achieve subfemtotesla sensitivity to magnetic fields without the cryogenic cooling required by supercon... read more

Optimization of an NV-Diamond CW-ODMR Magnetometer for Sentinel Lymph Node Detection
NV diamonds has shown great promise in the field of sensing and navigation due to their high sensitivity to small changes in magnetic fields. Its incorporation into magnetometers is favorable due to its functionality at room temperature and ability to be made into a small size. One crystal structure consists of a vacancy and the replacement of a ca... read more

2D Thermal Mapping of a Microchip Using Nitrogen-Vacancy Centers in Diamond
Introduction:
Infrared sensors are currently the most popular method for industrial temperature mapping, but they have limitations when applied to complex materials and micrometer-level scales. For example, infrared wavelengths can range from 0.7μm to 20μm. In addition, factors such as the emissivity of a material, as well as changes in ambie... read more

Optimizing Angular Multiplexing for Holograph Data Storage
Holographic data storage involves storing many two-dimensional images inside a certain volume filled with photopolymer by slightly tilting the reference beam. It presents a good alternative to hard drives, as it offers both high capacity and access rates. One of the main techniques this is achieved by is angular multiplexing. Conventional angula... read more
