Welcome to the Team, Sepideh!
We are excited to welcome Sepideh as the first member of our group! Sepideh completed her PhD studying ultrafast carrier dynamics in 2D van der Waals materials on femtosecond-to-picosend timescales using THz spectroscopy techniques. In a few weeks, she is joining us to push the limits even further - exploring lightwave-driven phenomena in quantum materials at even shorter timescales. 

We are looking forward to the exciting research ahead!

Our group is online!
We are excited to launch our research group at UCF starting January 2025! Our journey will begin with ordering equipment and building state-of-the-art laser labs. We even asked DALL-E to imagine what our lab could look like—take a look at the result on the left! We're committed to bringing our vision to life and making our lab as colorful, vibrant, and innovative as possible.

Our Nature Review Physics Article on Petahertz Electronics is out!

Together with our colleagues Matthias Kling (Stanford) and Philip Keathley (MIT) we explore the cutting-edge advancements in attosecond science and how they have paved the way for petahertz electronics. 

Last year, attosecond science was recognized with the Nobel Prize, and today, we continue to push the boundaries by using tailored optical waveforms to control charge carriers at petahertz frequencies—a potential monumental leap beyond traditional electronics. Current control in solids and nanostructures far beyond gigahertz is a reality, opening up possibilities for direct sampling the electric field of light, similar to what is done in a conventional oscilloscope but at petahertz frequencies - the analog age of petahertz electronics. Today, we work on on-chip integration, next-generation transistors, ultrafast digital logic, and optical communications.

Check out our new article on Ultrafast High-Harmonic Spectroscopy in Nature Physics!

We explore the rapidly evolving field of high-harmonic generation (HHG) in condensed matter, a technique that originally emerged in atomic and molecular systems but has now grown into a platform for investigating electronic band structures, topological properties, and many-body correlations in solids.

In the article, we cover the following key topics:

📍 Microscopic Mechanism of High-Harmonic Generation

📍 Probing Atomically Thin Two-Dimensional Materials

📍 Probing Topological Properties

📍 Probing Strongly Correlated Materials

📍 Time-resolved high-harmonic Spectroscopy

The future of attosecond science sits at the exciting intersection of ultrafast and materials science, and we are excited to see where the next years take us! If you are interested in this research direction, check out the Research Section.
