The lab explores the laws common to nonequilibrium phenomena through experiments on liquid crystals and bacteria.
AboutAbout the lab
Exploring the common laws hidden in nonequilibrium phenomena
The Takeuchi Lab conducts experiments to reveal the laws of statistical physics that arise from nonequilibrium phenomena.
It uses soft matter such as liquid crystals, granular materials, and colloids, as well as living organisms such as bacteria, as experimental materials.
The aim is not only to understand individual phenomena but also to extract physical laws that are common to them, independent of the specific phenomenon.
The lab's research spans nonequilibrium critical phenomena, active matter, and populations of microorganisms, and lab visits are welcome.
Key terms
- Nonequilibrium
- A state in which temperature and other quantities have not settled into uniformity (thermal equilibrium), and energy or flows continue to enter and leave
- Soft matter
- Soft materials such as liquid crystals, colloids, and granular matter, whose shape and properties change greatly under external forces
- Topological defect
- A singular point or line within an aligned arrangement where the orientation cannot be defined
- Active matter
- A collection of particles, such as bacteria, that move by using energy on their own

ResearchResearch themes
To understand the laws of statistical physics that nonequilibrium phenomena give rise to, the lab conducts experiments using soft matter such as liquid crystals, granular materials, and colloids, as well as biological materials such as bacteria. It designs experiments without being tied to particular methods or subjects, aiming to approach laws common to phenomena regardless of their specifics.
*Illustrative imageSeeing liquid crystal defects in 3D
The lab made line-shaped topological defects in liquid crystals visible with fluorescence and recorded their three-dimensional motion using high-speed confocal microscopy. It has confirmed, for the first time in a three-dimensional experiment, the scaling law of reconnection, in which defects exchange partners and rejoin.
*Illustrative imageTesting dynamic scaling laws with liquid crystals
Using liquid crystal experiments, the lab verified various universal dynamic scaling laws of what is known as Model A, which describes the process by which order forms in systems such as magnets (Ising ferromagnets).
*Illustrative imageKPZ universality at the interface of turbulence
The lab studies the fluctuations of the interface as turbulence, created by applying a voltage to a liquid crystal, spreads. The experiment allows direct comparison with the exact solutions for the universal laws known as the KPZ class, and the lab also built a setup in which laser holography lets the initial shape of the interface be freely designed.
*Illustrative imageBacterial collective motion and edge flows
By carefully engineering the geometry, the lab produced topological edge states in the collective motion of bacteria. This is a system that can be called controllable topological active matter.
