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 →

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

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 →

With the Levine group, we have posted a new paper about simulating transient absorption spectroscopy from first principles.

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 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 →

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.

Our work resolving valley polarization dynamics in monolayer WS2 is now featured as a DOE office of Science Highlight.

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.
