One- and two-dimensional quantum materials, known for their atomically thin layers bound by weak van der Waals interactions, possess distinct electronic, optical, and magnetic characteristics that respond sensitively to external conditions. This makes them crucial for advancing our understanding of quantum phenomena and developing future technologies. In this study, I will present recent experiments conducted under extreme conditions, including temperatures in the millikelvin range and pressures reaching up to 60 GPa. We conducted a systematic high-pressure investigation of the quasi-one-dimensional (Q1D) semiconductor TiS₃. Electrical resistance measurements under pressures up to 98 GPa revealed a unique progression of transitions, shifting from an insulating state at ambient conditions to the emergence of superconductivity above 70 GPa.
