• Heatmap plotter EXE ↓:

  • This application is designed to generate heatmaps from Renishaw map data files. Also, it can plot the specific points' spectrum to know how to choose the range. Users can fit the spectrum of specific points by just clicking the points on the plot.

• Spectrum fitting plotter EXE ↓:

  • This application is designed to plot Raman/PL spectrum and draw fitted curves on it. Users need to fit the curves with Origin to get the parameters first.

• Simulated the limited temperature that cavity and feedback cooling can reach.
• Calculated the combination of 2 cooling methods and certified that the new method's lowest temperature has the correct positive correlation with a low cavity decay rate.
• Simulated the new model using the Quantum Monte Carlo to find the lowest temperature the new method can reach. Compared with the separated cooling method, the new method can reach a lower temperature, which means the laser cooling method can also be enhanced with this new method.
• Reference and progress of the work: Github (Unpublished).

• Proposed to achieve the trapping of single atoms and combine fluorescence detection to achieve high-precision control of atomic positions by movable optical lattice.
• Participated in setting up the optical path for magneto-optical trap for ⁸⁷Rb. Independently built the double pass configuration to adjust the frequency of cooling light with Bragg diffraction.
• Led building and cleaning our second ultrahigh optical accessible vacuum system, in which we mounted a Rb atom dispenser for the MOT and optical dipole traps for ensembles and single atoms. The vacuum degree of the system has reached 3 × 10⁻¹¹ Torr.
• Independently pre-treated the optical fiber which will be used in the vacuum system and tested the mode field diameter of treated single mode fiber to optimize the mode matching between the modes of cavity and fiber.
• Independently designed control circuits and installed control electronics such as the microwave amplifier, radio frequency switch, and radio frequency generator into multiple integrated chassis to facilitate the connection of electrical devices in the optical path.
• Achieved the control time of atoms to 3s (Unpublished).
