Apr. 13, 2018♦ 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)
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!
Aug. 21♦ Summer school lecture note on KPZ posted on arXiv, entitled "An appetizer to modern developments on the Kardar-Parisi-Zhang universality class". Check it out! (link)
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)
