My research lies at the interface of quantum materials, advanced spectroscopy, and quantum optics, with the overarching goal of elucidating emergent phenomena arising from strong correlations and symmetry breaking. I am particularly interested in materials hosting unconventional ground states such as charge density waves, quantum spin liquids, altermagnetism, superconductivity, and topological phases. These systems provide fertile ground for exploring the interplay of spin, charge, lattice, and orbital degrees of freedom. Experimentally, I employ inelastic light (Raman) scattering as a symmetry-sensitive probe of low-energy excitations, performing measurements under controlled external perturbations including temperature, pressure, and magnetic field. This approach enables detailed studies of collective modes, phase transitions, and competing orders in quantum materials. Additionally, I use first-principles computational techniques, including density functional theory (DFT) and density functional perturbation theory (DFPT), to investigate electronic structure, lattice dynamics, and coupling mechanisms at a microscopic level. This combined experimental–theoretical framework facilitates both the interpretation of spectroscopic data and the prediction of new quantum materials.
In parallel, my research in quantum optics focuses on nonclassical light–matter interactions, quantum coherence, and photon correlations characterized through second-order correlation functions g(2)(τ). This work is motivated by applications in quantum spectroscopy, quantum information technologies, and toward developing new experimental platforms for probing quantum matter.
