A magneto-optical trap apparatus includes a vacuum vessel for encapsulating an atom to be trapped, an anti-Helmholtz coil for applying a magnetic field to an inside of the vacuum vessel, a laser device for generating a laser beam, and an irradiation device for irradiating the generated laser beam from a plurality of directions. The laser beam includes a first laser beam detuned from a first resonance frequency when the atom transits from a total angular momentum quantum number F in a ground state to a total angular momentum quantum number F=F+1 in an excited state, and a second laser beam detuned from a second resonance frequency when the atom transits from the total angular momentum quantum number F in the ground state to a total angular momentum quantum number F=F1 in the excited state, among transitions from J=0 in a ground state to J=1 in an excited state.

Atom-scale particles, e.g., neutral and charged atoms and molecules, are pre-cooled, e.g., using magneto-optical traps (MOTs), to below 100 K to yield cold particles. The cold particles are transported to an atom-chip cell which cools the cold particles to below 1 K; these particles are stored in a reservoir within the atom-chip cell so that they are readily available to replenish a sensor population of particles in quantum superposition. A baffle is disposed between the MOTs and the atom-chip cell to prevent near-resonant light leaking from the MOTs from entering the atom-chip cell (and exciting the ultra-cold particles in the reservoir). The transporting from the MOTs to the atom-chip cell is effected by moving optical fringes of optical lattices and guiding the cold particles attached to the fringes along a meandering path through the baffle and into the atom-chip cell.

Methods and devices for single cell analysis using fluorescence lifetime imaging microscopy (FLIM) are disclosed. The methods utilize microfluidic devices which use traps to immobilize cells for FLIM analysis. The analysed cells may be sorted before or after imaging and may be plant, animal, or bacterial cells. Analysis of the FLIM data may use a phasor plot and may be used to identify a metabolic pattern of the single cells.

An atomic clock system includes a magneto-optical trap (MOT) system that traps alkali metal atoms in a cell during a trapping stage of each of sequential coherent population trapping (CPT) cycles. The system also includes an interrogation system that generates an optical difference beam comprising a first optical beam having a first frequency and a second optical beam having a second frequency different from the first frequency. The interrogation system includes a direction controller that periodically alternates a direction of the optical difference beam through the cell during a CPT interrogation stage of each of the sequential clock measurement cycles to drive CPT interrogation of the trapped alkali metal atoms. The system also includes an oscillator system that adjusts a frequency of a local oscillator based on an optical response of the CPT interrogated alkali metal atoms during a state readout stage in each of the sequential clock measurement cycles.
