About Paper:

This project explores both experimental hardware design and theoretical quantum optics. In the first phase, I designed and fabricated a current control module for magneto-optical trap (MOT) applications. This task involved schematic and layout design of a custom PCB, mechanical fabrication of an aluminum enclosure, integration of thermal management using fan-assisted cooling, and low-noise circuit testing to ensure robust current stability for magnetic coils. The second phase focuses biphoton generation via four-wave mixing in cold atoms. Using perturbation theory and nonlinear susceptibility analysis, I modeled the biphoton wavefunction as a convolution of the system's optical responses. I analyzed its time-domain form to understand how phase- matching, detuning, and nonlinear coupling shape the two-photon correlations observed in experiments. Keywords: [no keywords provided]
