The lab explores quantum many-body systems and critical phenomena using analytical methods.
AboutAbout the lab
Tackling problems with infinitely many degrees of freedom through field theory and solvable models.
The Sakai Lab addresses the question of how to handle problems with infinitely many degrees of freedom in statistical mechanics and quantum field theory.
The lab studies phenomena arising from nonperturbative quantum effects in quantum many-body systems, and universal properties of critical phenomena, using analytical methods such as field theory and solvable models.
The lab also investigates the mathematical structures hidden behind solvable models.
Key terms
- Solvable model
- A theoretical model that can be solved exactly by calculation
- Critical phenomena
- Phenomena observed near the boundary where the state of a material switches. Common properties appear even in different materials
- Quantum field theory
- A theory of quantum mechanics that treats particles as the behavior of fields spreading through space
ResearchResearch themes
The lab investigates phenomena in quantum many-body systems and critical phenomena, centered on how to handle problems with infinitely many degrees of freedom in statistical mechanics and quantum field theory. Listed research topics include conformal field theory and stochastic processes, nonequilibrium phenomena in (1+1)-dimensional quantum systems, quantum solitons, and quantum computers.
