Graduate student Jin Bakalis won the prize for best poster at Chemistry Research Day with her poster titled: “Ultrafast Dynamics in Graphite/graphene probed with time-resolved momentum microscopy.” Here is a photo of Jin receiving the award from Dept. Chair Peter … Continue reading →

It has been a long brutal year, but things are starting to get a little bit more normal. We were actually all in the same place together today for the first time in over a year to take the group … Continue reading →

Postdoc Grzegorz has been awarded a Marie Skłodowskiej-Curie fellowship from the European Commission. Congratulations! A press release can be found HERE. The Stony Brook CE-TAS spectrometer is in the Polish news!

While non-perturbative high harmonic generation (HHG) has been a hot topic for decades, cascaded HHG is also a very rich problem and can have much higher efficiency. In collaboration with the Diddams group at NIST, we’ve investigated frequency comb generation … Continue reading →

After getting all the systematics under control, we have written a paper on our broadband cavity-enhanced transient absorption spectrometer. This takes CE-TAS from a one-of demonstration to a real chemical physics tool. The paper is available on the arXiv here: … Continue reading →

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

With recent/upcoming graduations, we have several projects available for graduate students to do research in the Allison lab. Please contact Tom Allison if interested.

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 … Continue reading →

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 … Continue reading →

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 … Continue reading →
