A statistical science lab that uncovers causes through data and mathematics.

The Kuroki Lab studies statistical science that uncovers the “why” behind phenomena through data and mathematics, centered on statistical causal inference. Its central goal is to develop and put into practice statistical analysis methods aimed at applications in fields such as medicine, engineering, social sciences, and information science. The lab conducts joint research with companies and academic research institutions, and offers hands-on opportunities to students who are interested in analyzing real-world data and hope to enter graduate school. As a rule, the lab accepts third- and fourth-year undergraduates in the Mathematical Science Education Program.

A lab developing new magnetic and superconducting materials.

The Uehara Lab studies magnetism and superconductivity at low temperatures, and works to develop superconductors and magnetic materials that show useful physical properties. Its ultimate goal is to synthesize a material that becomes superconducting at room temperature. Beyond the search for superconductors, the lab also aims to open up new and interesting physical properties, such as colossal magnetoresistance. The lab also carries out measurements of magnetic, thermal, and electrical conduction properties, as well as theoretical analysis of experimental results.

A lab that builds new nanostructures from atoms and molecules and explores their surface properties.

The Shinya Ohno Lab studies how to build new nanoscale structures using atoms and molecules as basic building blocks, and investigates their physical properties. Its goal is to evaluate the properties of these structures in detail and, based on that knowledge, propose new devices. The lab uses a combination of various surface analysis techniques, such as scanning tunneling microscopy and photoelectron spectroscopy. The undergraduate reading-and-presentation seminar is run jointly with the Shudo Lab.

The lab fabricates tiny electronic devices from superconductors and semiconductors and studies their properties.

Shimazu Lab fabricates tiny electronic devices from superconductors and semiconductors and studies their properties. The devices range from a few micrometers to a few nanometers in size, and are made using microfabrication techniques such as photolithography and electron beam lithography. The lab examines their physical properties over a wide temperature range, from room temperature down to about 20 mK. In graduation research, students study the condensed matter physics of materials such as semiconductors thoroughly and carry out research centered on experiments.

The lab investigates the behavior of electrons on solid surfaces through both measurement and calculation.

Shuto Lab studies phenomena that occur on solid surfaces through both experiments and theoretical calculations. A solid surface is a special two-dimensional space where molecules and atoms interact with the solid, and it requires a different treatment from the interior of the solid. Taking advantage of this environment, the lab aims to clarify the formation and control of nanoscale structures, as well as changes in electronic states upon excitation and the dynamic processes involved. The lab also works on phenomena that form the foundation of next-generation devices and on the development of new materials.

A solid-state physics lab focused on how the properties of materials change when exposed to light.

Sekiya Lab makes materials with distinctive structures on its own and measures their optical, electrical, and magnetic properties. The lab also focuses on how properties change when light is applied, hoping that distinctive physical properties will emerge. Research subjects include single crystals of titanium dioxide, thin films of oxynitrides that are attracting attention as fuel cell catalysts, and light-responsive molecules and dye aggregates. The lab is said to be open to visits and tours at any time, and visitors are advised to make an appointment whenever possible.

A lab that predicts the properties of solids and molecules with quantum mechanics, without separating the two.

The Raebiger Lab studies the properties of solids and molecules using theories from quantum chemistry and condensed matter physics. The lab regards the distinction between solids and molecules as artificial, and holds that the properties of any material can be predicted by solving the same Schrödinger equation. Many of its research themes deal with how 3d transition metal atoms behave in the various environments found in solids and molecules. The lab's website is in English only, and presents the lab under the name SSMT (Solid State and Molecular Theory).

A lab that explores material properties such as superconductivity using first-principles calculations.

The Kawamura Lab uses first-principles calculations to study material properties such as superconductivity, phonons, and surfaces and interfaces. In superconductivity, the lab works on predicting by calculation the transition temperature at which a material becomes superconducting, and on investigating the superconducting gap. The lab also develops computational programs and conducts research using data science and machine learning. The lab was founded in April 2025 and belongs to the Physical Engineering Education field.

A lab that uses theory to explore uncharted phenomena arising from the interaction between light and matter.

The Bamba Lab uses the methods of theoretical physics to discover and explain previously unknown phenomena that arise from the interaction between light and matter. Its research centers on a phenomenon called the “superradiant phase transition,” which occurs through light–matter interaction. The lab states that research on light is thriving in industry and applications, but few theoretical researchers pursue the underlying principles of the phenomena. The lab's December 2023 guide for lab assignment also lists the analysis of joint experiments with experimental groups in the United States and elsewhere as an example of a research theme.
