Over 50 graduate students, postdoctoral researchers, and staff gathered in the JILA Auditorium on Thursday, March 13th, for the next session of the Graduate Student Seminar Series, hosted by the JILA Association of Graduate Students (JAGS) and the Graduate Association of Students in Physics (GASP). The event began with a provided lunch, allowing attendees to connect with colleagues before diving into two fascinating research presentations, one from the Regal group in JILA and one from the Lee group in the University of Colorado Boulder physics department. 

First, Hope Whitelock (Lee Group) discussed her research on the Observation of Field-Split Crystal Electric Field Levels in CsErSe₂. In her talk, she detailed the unique electronic properties of this layered material, which belongs to a class of quantum materials with potential applications in next-generation electronics and quantum information science. By studying how crystal electric field levels split under different conditions, Whitelock’s research better explains the complex interactions that drive exotic material behaviors. Her findings contribute to the growing field of condensed matter physics and have implications for developing materials with tunable quantum properties.

Next, Steven Pampel (Regal Group) presented his work on Light-assisted Collisions in Optical Tweezers. His talk explored how optical tweezers—highly focused laser beams used to trap and manipulate atoms—can be used to control interactions between atoms. By harnessing light-assisted collisions, researchers can fine-tune these interactions, paving the way for advancements in quantum computing and precision measurements. Pampel’s research highlights the intricate role of atomic collisions in trapped systems, offering more profound insight into how light can influence quantum mechanical behaviors at ultra-cold temperatures.

Beyond the exciting research, the seminar fostered a space for graduate students and postdocs to refine their presentation skills, exchange ideas, and engage in discussions outside their specific research areas. The event was also streamed to NIST, ensuring accessibility for those unable to attend in person.

This seminar series continues to be an excellent opportunity for early-career researchers to showcase their work, gain feedback, and strengthen the collaborative scientific community at JILA.
