AboutAbout the lab
Uncovering the behavior of electrons and atomic nuclei through computation
The Sugino Lab conducts research in computational materials science, using numerical simulation to investigate the properties of materials.
Its research field is first-principles calculation, which solves the Schrödinger equation to clarify the behavior of the electrons and atomic nuclei that make up matter.
In this field, it is important to develop methods that solve quantum many-body systems of electrons and atomic nuclei efficiently and accurately, and to build models for simulating complex materials.
Key terms
- First-principles calculation
- A method of calculating the properties of matter from the fundamental equations of quantum mechanics, without relying on experimental values
- Schrödinger equation
- The fundamental equation of quantum mechanics that governs the behavior of microscopic particles such as electrons
- Phonon
- The collective vibration of atoms oscillating together in a crystal, treated as if it were a particle
ResearchResearch themes
The lab studies material properties using first-principles calculations, which uncover the behavior of electrons and atomic nuclei starting from the Schrödinger equation. It places emphasis on developing methods that solve quantum many-body systems efficiently and accurately, and on modeling for the practical simulation of complex materials.
*Illustrative imageElectron Transfer at Surfaces and Interfaces
The lab investigates how a moving proton (hydrogen ion) in a solvent interacts with a metal electrode. It has shown that the coupling between proton motion and solvent vibrations suppresses electron transfer, and has clarified the mechanism by which energy is dissipated in the metal.
*Illustrative imageMagnetism in Superconducting Materials
Using first-principles density functional theory calculations, the lab has clarified the magnetic states that appear in electron-doped infinite-layer cuprates. It has shown how magnetic fluctuations and element substitution affect the electronic states.
*Illustrative imageElectron–Phonon Interaction
The lab studies the phenomenon in which the band gap changes due to quantum and thermal fluctuations of the lattice. By reframing this from the perspective of optical transitions, it has explained why the magnitude of the change differs from material to material.
