Unconventional superconductors: High-temperature superconductors (copper oxides and Fe-pnictides) and heavy fermion systems,
We use Fourier transform infrared (FTIR) spectrometers and a monochromatic type optical spectrometer to cover a broad spectral range from far infrared (FIR) through ultraviolet (UV). We investigate low-lying (or intraband) optical excitations, characteristic collective modes including pure and hybrid phonon modes, and electronic (interband) transitions of various novel quantum material systems. The quantum material systems would be,
