Hello World Again… hopefully for the last time.
Our web server died again, of course right during proposal season. Ugh. This time it was a Raspberry Pi. From now no more DIY web servers. We have migrated to a professional solution hosted by GoDaddy, with new domain allisongroup.net. … Continue reading
New Perspective Article
We have posted a new “perspective” article on cavity-enhanced HHG for high-performance photoemission experiments. It can be found here: https://arxiv.org/abs/2410.11589
Mike Wahl Completes M.S.I. Degree
Michael Wahl has completed his M.S.I. degree in the Allison lab, developing tunable frequency combs with arbitrary (0-60.5 MHz) for the Allison lab tr-ARPES instrument. This is the last piece of the tr-ARPES laser puzzle. Mike is off now to … Continue reading
New CE-TAS Paper
With the Levine group, we have posted a new paper about simulating transient absorption spectroscopy from first principles.
Non-thermal Pseudospin Dynamics in Graphene
We have posted a new paper regarding imaging pseudospin dynamics in graphene. Working at the low excitation fluences enabled by our unique tr-ARPES instrument, we are able to vary the relative importance of electron-electron and electron-phonon scattering on the dynamics … Continue reading
Myles Silfies Completes Ph. D.
Myles Silfies has successfully defended his dissertation and completed his Ph. D. Many thanks to committee members Cyrus Dreyer, Chris Johnson, and A. J. Fleisher for serving on Myles’ committee. Also thanks to Tom Weinacht (pictured at left) for helping … Continue reading
Alice Kunin featured on Princeton Chemistry Webpage
Allison lab postdoc Alice Kunin will start as an assistant professor at Princeton in Jan. 2024 where she will continue to develop advanced photoelectron spectroscopy techniques. Princeton has made a news post with more details.
Allison Lab Research Featured in DOE Science Highlight
Our work resolving valley polarization dynamics in monolayer WS2 is now featured as a DOE office of Science Highlight.
Ultrafast internal conversion and photochromism in gas-phase salicylideneaniline
We have posted a new paper regarding the ultrafast dynamics salicylideneanaline, combining CE-TAS measurements with ab initio theory from the Levine group. The paper can be found here: https://arxiv.org/abs/2306.05645
Sergii’s Farewell Dinner
Sergii Chernov is leaving us soon to start a new position at PETRA III. It was great to get the whole group together, with both new students and seasoned veterans, for an evening out.
