A lab that directly “sees” the electrons inside materials using photoemission spectroscopy.
AboutAbout the lab
Directly “seeing” how electrons behave
The Kondo Lab studies the fundamental principles of how electrons cooperate inside materials to give rise to new quantum phenomena such as superconductivity.
Targeting high-temperature superconductors, topological materials, and atomic-layer thin films, the lab approaches the underlying mechanisms by directly “seeing” electron behavior with photoemission spectroscopy.
Using state-of-the-art laser-based photoemission spectroscopy developed at the Institute for Solid State Physics, the lab captures electrons in multiple dimensions: energy, momentum, spin, time, and space.
Students use cutting-edge instruments themselves and can also take part in developing new instruments.
Key terms
- Angle-resolved photoemission spectroscopy
- A method that shines light on a material and measures the energy and direction of the emitted electrons to study how electrons move inside the material
- High-temperature superconductivity
- A phenomenon in which electrical resistance drops to zero at relatively high temperatures. It has been found in materials such as cuprates
- Topological materials
- Materials in which the topological (“shape”-related) character of the electronic states gives rise to special electronic states only at the surface or edges
- Strongly correlated electron systems
- A class of materials in which electrons strongly influence one another, producing phenomena that cannot be predicted from individual electrons

ResearchResearch themes
The electrical and magnetic properties of a material are determined mainly by the behavior of the electrons moving through it. The lab directly observes electronic states with angle-resolved photoemission spectroscopy using state-of-the-art lasers, tackling difficult problems in solid state physics.
*Illustrative imageAngle-Resolved Photoemission Spectroscopy (ARPES)
By shining light on a sample and measuring the energy and angle of the emitted electrons, the lab directly observes the relationship between electron momentum and energy. The lab's laser-based instruments are extended with ultrahigh resolution, spin resolution, and time resolution, and the lab also uses nano-ARPES at synchrotron radiation facilities.
*Illustrative imageFermi Surfaces of Cuprate High-Temperature Superconductors
In high-temperature superconductors, whether the antiferromagnetism of the parent material can coexist with superconducting electrons has been a matter of debate. The lab examines multilayer cuprates with flat, uniform crystal surfaces, aiming to clarify the mechanism of high-temperature superconductivity.
*Illustrative imageElectronic States of Topological Materials
The lab observes the electronic states of materials that are distinguished by the “shape” of their electronic states, such as topological insulators and Weyl semimetals. It was the first in the world to observe the electronic states of a weak topological insulator, in which surface states appear only on the side faces of the crystal.
*Illustrative imageUnusual Phenomena in Strongly Correlated Electron Systems
Focusing on strongly correlated electron systems, in which electrons strongly influence one another, the lab aims to clarify new mechanisms mainly through ARPES observations. In a phenomenon where the magnetic arrangement changes one after another with slight changes in temperature, the lab captured a large change in how the electrons move.
