We study superconductors—materials that conduct electricity without resistance and expel magnetic fields below a critical temperature (Tc). While most known superconductors work only at very low temperatures, our research aims to understand and discover materials that can superconduct at higher temperatures. Using electrical transport, magnetization, and thermodynamic measurements under ambient and high-pressure conditions, we explore their fundamental properties to advance practical applications.
Topological insulators are quantum materials distinguished by an insulating bulk and conducting surface states protected by topology, making them exceptionally stable against disorder. These robust surface states offer significant potential for future electronic devices. Our group investigates topological materials using magnetotransport techniques. Under high magnetic fields, we observe quantum oscillations—such as Shubnikov–de Haas (SdH) and de Haas–van Alphen (dHvA) effects—that provide valuable insights into the material’s electronic structure. By analyzing these oscillations, we determine whether a material is topologically trivial or non-trivial and explore the properties of its surface states.
High pressure is a powerful and clean technique for tuning the properties of materials without introducing impurities. Previous studies have shown that applying pressure can induce superconductivity, drive transitions from topologically trivial to non-trivial phases, and alter magnetic states. Our group utilizes high-pressure methods to investigate and modify the behavior of superconducting, magnetic, and topological materials.
Density Functional Theory (DFT) is a powerful computational method used to investigate the electronic, thermal, and magnetic properties of materials. We employ DFT-based simulations to support and interpret our experimental findings, providing deeper insight into the underlying physics of complex materials.
