My research focuses on strongly correlated electron systems, and how the underlying quantum mechanics gives rise to unconventional electronic states, such as superconductivity.
For this purpose, I explore how exactly electrons flow through materials. This allows me to characterise various quantum mechanical phases, and to search for signatures of unconventional or "strange" physics. Specifically, I am interested in the shape of the Fermi surface, which marks a three-dimensional representation of the electron motion in metals.
To carry out my research, I push our experimental toolset to its limits. Specifically, I focus on a range of techniques (such as piston cylinder cells and Diamond anvil cells) to reach pressure of several 10,000 bars. By varying the applied pressure, I carefully tune bespoken materials across quantum phase transitions, searching for signatures of quantum criticality, enhanced superconductivity, and strange and novel physics. Next, I combine these pressures with some of the world's strongest magnetic fields, and the lowest temperatures available, to observe tiny oscillatory variations in the electrical resistivity, known as quantum oscillations. Their field-, temperature- and pressure dependence encapsulate fundamental properties which I seek to extract. Finally, by combining quantum oscillations with ARPES measurements, these methods allow me to study how exactly the electrons in a material behave and how they interact.
In February 2021, I joined the Quantum Materials Department (Prof. Takagi) at the Max Planck Institute for Solid State Research in Stuttgart, Germany, whilst I stay as a long-term visitor in Oxford.
