We study quantum phenomena in different condensed matter and solid-state systems using a variety of experimental methods, such as electrical transport measurements, optical cavities, electron spin (ESR) and nuclear magnetic (NMR) resonances, and microfabrication techniques. Of particular interest are 2D electrons on liquid helium, coupled electron-nuclear systems in crystalline antiferromagnets, and color centers in diamond. We like discovering new interesting phenomena and thinking about their potential applications for quantum technologies.
