At the Fujishiro Laboratory, we aim to explore new electronic functions beyond the conventional frameworks of semiconductors, metals, and magnetic materials, using quantum materials in which topology, magnetism, and electron correlations are deeply intertwined.
The diverse physical phenomena exhibited by quantum materials arise from the internal degrees of freedom of electrons—such as charge, spin, and orbital character—as well as from their complex interactions inside solids. By controlling these degrees of freedom and interactions at high energy scales through state-of-the-art materials engineering techniques, we seek to create materials in unexplored parameter regimes that humanity has not yet reached, as well as in energetically unstable regimes that natural materials intrinsically tend to avoid.
Specifically, we investigate physical properties under extreme conditions such as ultrahigh pressure, low temperature, high magnetic field, and high electric current, using techniques including single-crystal microdevice fabrication and ultrahigh-pressure experiments with diamond anvil cells. Through these efforts, we aim to establish design principles for new phenomena that can lead to next-generation low-power electronics and spintronics.
