Allison Research Group

Grzegorz Kowzan has returned to our group now as a postdoc after completing is Ph. D. in Toruń. Welcome back!

Usually, we update the group photo every Spring. Due to the COVID-19 pandemic, we now all work remotely. So our latest group photo is a screenshot of a Zoom meeting…

All are doing OK so far, with many projects to work on remotely. We remain motivated by our basic science goals, realizing that basic science, including the development of tools to image the microscopic, underlies underlies much of our modern-day scientific framework for understanding the novel coronavirus.

Two new postdocs have joined our effort. Sergey Chernov comes from Mainz with extensive experience in ARPES and time-of-flight momentum microscopy. Alice Kunin comes from Berkeley with experience in ultrafast optics and time-resolved photoelelectron spectroscopy.

Both have hit the ground running.

One of the Allison lab core competencies has been resonantly enhancing frequency combs in high-finesse optical cavities. In a paper posted to the arXiv here, we have extended this technology to a widely tunable platform for the first time. This enables broadband cavity-enhanced ultrafast spectroscopy, among other applications.

We posted a new paper about our high-power mid-IR comb development.

Neomi Lewis completed a summer research program at the Max Planck Institute for Quantum Optics in Garching, Germany. Now she’s back in the Allison lab.

Ryan Hou, an undergraduate from Columbia University, completed summer research in the Allison group, working on Cavity-Enhanced Ultrafast Spectroscopy

Peng Zhao successfully defended his dissertation, and hands the ARPES torch to Jin Bakalis (left).

Our first Ph. D. graduate, Yuning Chen, was selected as a finalist for the APS Justin Jankunas prize in Chemical Physics. Yuning presented her work beautifully in an invited prize session talk at the 2019 APS March Meeting. Congratulations to Yuning for this great honor.

Paper on tunable visible comb generation posted to the arXiv now here. Many details about our tunable visible comb frequency comb setup covering > 9000 cm¯¹ of tuning range.
