Our article “Multioctave supercontinuum generation and frequency conversion based on rotational nonlinearity” was published today in Science Advances! This work was led by John and Murty, but included contributions from many others, including a collaboration with Bonggu Shim’s group at Binghamton University.

Our theory paper on electron-electron correlations in BaTiO3 was published in the Journal of Physics: Condensed Matter! This work was the result of a joint experiment/theory collaboration with Dr. Volodymyr Turkowski, and supported by the NSF under award no. 1809181.

Congratulations to Chau Truong for passing her Dissertation Proposal, and moving into PhD candidacy! Chau’s dissertation will focus on developing a source of isolated attosecond pulses using our Yb:KGW laser, and applying them to study dynamics in atomic systems using attosecond interferometry.

Better late than never – Mike is now on Twitter. Follow him for updates on the LUMAS group: https://twitter.com/ProfMChini.

Today, Erin Crites successfully (and virtually!) defended her Honors in the Major thesis, entitled “Polarization Dependence of High Order Harmonic Generation from Solids in Reflection and Transmission Geometries”. Erin joined the group as a Freshman, and will graduate this semester. Next, she will pursue a PhD in Physics from the University of North Carolina, where we expect even bigger and better things are in store for her. Congratulations, Erin!

Shima completed her PhD today, with the successful (and virtual!) defense of her dissertation entitled “Symmetry and High Harmonic Spectroscopy in Solids”. Many congratulations to (Dr.) Shima!!!

John Beetar was interviewed about his research for UCF Today, in support of Student Research Week. Read the story here.

Our latest article, which details a new setup for XUV time- and angle-resolved photoemission spectroscopy (trARPES) based on high-order harmonics from a Yb:KGW laser technology, has been published in Review of Scientific Instruments. Using our unique light source, we demonstrate the potential to achieve extremely high energy resolution of 21.5 meV in trARPES. This paper is a result of a collaboration between our group and Madhab Neupane’s group at UCF, with support from scientists at SUNY Buffalo and the Polish Academy of Sciences. Congratulations to postdoctoral scientist Yangyang Liu, who led the project. We are excited about the new prospects for quantum materials research which will be enabled by this unique setup!

Our study on polarization properties of high-order harmonics generated from ZnO crystals has been published in Journal of Physics B. This paper is a result of a collaboration between our group and theorists from Kansas State University and Nanjing University of Science and Technology.

We are happy to welcome two new PhD students into the LUMAS group. Jonathan Nesper joins us after completing his BSc in Physics at UCF in Spring 2019. Jonathan has actually been involved in our group since 2015 as an undergraduate researcher, and we are happy to have him continue with us as he seeks a PhD in Physics. Ahmed Yousif is a new student in the Optics PhD program. He joins us after completing a BSc in Physics from the University of Toronto and a MSc in Physics from Michigan State University. Welcome, Jonathan and Ahmed!
