May 1, 2018♦ Became an associate professor at the University of Tokyo, Department of Physics. At Tokyo Tech, I became a visiting associate professor.
Apr. 26♦ Paper posted on arXiv, entitled "Lane formation and critical coarsening in a toy model of bacterial competition". Check it out! (link)
Apr. 17♦ Awarded the "The Young Scientists' Prize" of "The Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology" of Japan! The awarded research is experimental studies that tested universal laws of non-equilibrium interface fluctuations.
Apr. 13♦ Paper published in Phys. Rev. E (Rapid Communication), where we numerically studied what happens if fast and slow interfaces grow together. We found the relevance of GSE random matrices in a representative situation. (link)
Apr. 1♦ Summer school lecture notes on KPZ published in Physica A, entitled "An appetizer to modern developments on the Kardar-Parisi-Zhang universality class". Check it out! (link)
Mar. 14♦ Awarded the "Education Prize for Young Teachers in School of Science" from School of Science, Tokyo Tech!
Dec. 21, 2017♦ Awarded the "3rd Suematsu Prize" from Tokyo Tech!
July 21♦ Paper published in Phys. Rev. Lett., where we found both experimentally and numerically that KPZ-class interfaces growing inward from a ring follow universal statistical rules of the flat interfaces, instead of the circular ones. (link)
June 8♦ Paper published in J. Phys. A, where the 1/f a-type power spectrum was characterized by recently proposed exponents and shown to contain universal information of the stationary KPZ subclass. This is an invited paper for Special Issue "Emerging Talents". (link to paper, link to Special Issue)
Mar. 24♦ Paper published in Phys. Rev. Lett., where an analytic expression for the two-time joint probability distribution for the circular KPZ subclass were derived and found in agreement with experiments and numerics. (link)
Sep. 7, 2016♦ Paper posted on arXiv, where we numerically identified the directed percolation critical behavior at a phase transition to quantum turbulence. (link)
Aug. 19♦ Awarded the "2016 Tokyo Tech Challenging Research Award"! See the official announcement.
July 20♦ Paper online published in J. Stat. Phys., which reports an unexpected connection between KPZ-class fluctuations and weak ergodicity breaking. (link)
July 7♦ Paper published in Phys. Rev. Lett., which reports numerical evidence that the inertial manifold of a spatially-extended chaotic system can be characterized by unstable periodic orbits. (link)
