Light-Matter Interaction: Fundamental Physics and Device Applications
Our research focuses on light-matter interactions to drive and probe quantum states in condensed matter, including nanomaterials, magnets, strongly correlated materials, and superconductors, under extreme conditions of temperature and magnetic fields. By utilizing advanced spectroscopic techniques, we investigate charge, spin, and vibrational dynamics in these materials. Our lab is equipped with state-of-the-art instruments, such as the RAMBO system, a unique 30-T pulsed magnet setup combined with ultrafast and nonlinear optical spectroscopy, enabling us to explore a variety of modern materials both in free space and within cavities.
Our primary research interests include:
- Matter driven out of equilibrium
- Optics and photonics in quantum materials
- Quantum optics in condensed matter
- Dicke phenomena, especially in cavities
- Quantum information processing and spintronics
The ultimate goal of our work is to gain a microscopic understanding of non-equilibrium cooperative phenomena in many-body systems, which will not only deepen our knowledge of condensed matter physics but also pave the way for novel opto-electronic devices and the solid-state realization of quantum information technologies, including computation and communication.
