Tokura Lab
Machine-translated · View original
A lab that opens up new electronic phases in materials where electrons strongly influence one another.
AboutAbout the lab
Controlling the many degrees of freedom of electrons to reach new electronic phases
The Tokura Lab studies strongly correlated electron systems, materials in which electrons strongly influence one another, and works to discover new electronic states in them.
In these materials, electronic properties such as charge, spin, and orbital are strongly pronounced, giving rise to a wide range of phenomena including high-temperature superconductivity.
Alongside studying solid-state physics and reviewing the literature, students carry out experimental research that includes synthesizing samples and measuring their physical properties.
Key terms
- Strongly correlated electron system
- A material in which the repulsion between electrons is so strong that electrons cannot be treated one by one as independent particles. It shows a wide range of properties as a collective of electrons.
- Topological insulator
- A special material whose interior does not conduct electricity but whose surface does carry current.
- Thermoelectric effect
- A phenomenon in which heat and electricity are converted into each other. It can generate electricity from a temperature difference, or produce cooling using electricity.

ResearchResearch themes
The lab aims to investigate the electronic states of strongly correlated electron systems, control them at will, and open up new electronic properties. Using diverse methods such as sample synthesis, thin-film fabrication, and device fabrication, it tackles problems in strongly correlated electron physics and cross-correlation physics.
*Illustrative imageElectronic properties emerging near the Mott transition
In metals where strong electron correlations remain (near the Mott transition), high-temperature superconductivity and other phenomena have been found in oxides of copper, manganese, and other elements. The lab studies the collective states of these electrons and aims to control them at will.
*Illustrative imageSurface electrons of topological insulators
In topological insulators, which are insulating inside but carry current only on the surface, the surface electrons are massless and their spins are aligned. Through thin-film fabrication and device fabrication, the lab explores the phenomena these electrons produce.
*Illustrative imageEfficient conversion between heat and electricity
The lab aims to achieve highly efficient thermoelectric conversion, which could lead to power generation from waste heat, by taking advantage of special band structures and the properties of strongly correlated electron systems, using high-pressure synthesis, thin-film fabrication, and band structure calculations.
