A lab that searches for new materials that show unknown quantum phenomena.

AboutAbout the lab
Betting on the unknown to find new materials
The Emergent Quantum Materials Science Lab searches for new materials full of unknown quantum phenomena and studies their properties.
Because it is difficult to make a material with a desired function exactly as designed, the lab conducts inductive materials exploration that draws on experience and intuition.
The lab does broad work on material synthesis under environments such as ultrahigh pressure and ultrahigh vacuum, and on measurements of properties such as magnetism, electrical conductivity, and thermal transport. Recently it has also made use of first-principles calculations and Bayesian optimization.
On the lab's website, it is introduced under the name "Ishiwata Lab."
Key terms
- Inductive materials exploration
- A way of searching in which, instead of designing a material from a desired function, one decides which materials to try based on experience and intuition
- First-principles calculation
- A method that calculates the properties of materials from the fundamental laws of quantum mechanics, without relying on experimental data
- Bayesian optimization
- A method that probabilistically chooses the next conditions to try based on past results, in order to find good conditions with few trials
