Research Interests: Theory of Nonequilibrium Quantum Many-Body Physics at the Interface between Condensed Matter Physics, AMO Physics, and Quantum Information

I am interested in strongly correlated phenomena in condensed matter physics, particularly in open quantum systems with ultracold atoms. Recently, I am working on many-body physics by using both analytical and numerical methods, such as Bethe ansatz, conformal field theory, and (non-Hermitian generalization of) density-matrix renormalization group analysis. We are always looking for motivated students and postdocs who belong to Department of Physics, Osaka Metropolitan University. If you are interested, please contact me for further information.

Recent Research

 Novel Many-Body Measurement-Induced Universality

Recently, quantum measurement has attracted great attention as it causes drastic nonequilibrium quantum phenomena such as in condensed matter physics and quantum information sciences. We have revealed that subsystem fluctuations in many-body systems can exhibit novel measurement-induced universality and are accessed in experiments without postselection.
