Rate My Professor Denis Karaiskaj

His research focuses on optical and laser spectroscopy techniques, including time-resolved and nonlinear two-dimensional spectroscopy, two-dimensional spectroscopy at extreme magnetic fields, magneto-optic Kerr effect measurements, and silicon-based atomic clocks. Karaiskaj explores light-matter interactions in condensed matter systems such as monolayer transition metal dichalcogenides, quantum wells, layered GaSe, and InSe crystals. Key publications include "Biexcitons in monolayer transition metal dichalcogenides tuned by magnetic fields" (Nature Communications, 2018), "Strong quantum coherence between Fermi liquid Mahan excitons" (Physical Review Letters, 2016), "Optical coherence in atomic-monolayer transition-metal dichalcogenides limited by electron-phonon interactions" (Physical Review Letters, 2016), "Superradiant coupling effects in transition-metal dichalcogenides" (Optica, 2018), and "Two-Quantum Many-Body Coherences in Two-Dimensional Fourier-Transform Spectra of Exciton Resonances in Semiconductor Quantum Wells" (Physical Review Letters, 2010). He holds U.S. patents for "Silicon-based atomic clocks" (8,816,784 B1, 2014), "Atomic clock using a photodetector" (9,052,698 B1, 2015), and "Silicon-based magnetometer" (9,753,102 B1, 2017). In June 2025, Karaiskaj received a BRAG grant of up to $25,000 from the University of South Florida Foundation and USF Research Foundation for developing a smaller, cheaper, and more energy-efficient silicon-based atomic clock for applications in navigation, GPS, and precision timing devices. His scholarly work has accumulated over 2,500 citations, reflecting its impact in the field of Physics.
