The International Institute for Sustainability with Knotted Chiral Meta Matter (WPI-SKCM²) is an international research institute hosted by Hiroshima University, located in Higashi-Hiroshima, Japan. It is one of 18 institutes funded by the World Premier Research Center Initiative (WPI)[1] which is a grant funded by the Japan Society for the Promotion of Science.
The institute employs a multi-disciplinary approach to research with a focus on connecting pure mathematics to other disciplines such as biology, chemistry, earth and planetary sciences, materials science, and engineering with the common research theme of chiral knots.[2] The institute aims to address issues of sustainability using artificial materials designed to exhibit desirable properties using knotted structures[2]. One example of such material created at the institute is a thermally insulating and transparent aerogel created from cellulose nanofibers.[3][4]
History
The International Institute for Sustainability with Knotted Chiral Meta Matter was created in November 2022.[5] The Ministry of Education, Culture, Sports, Science and Technology chose to fund SKCM² as a part of the ongoing effort to develop globally visible research centers in Japan through the program entitled "WPI".[5]
Dr. Ivan Smalyukh was chosen as the director of the institute.[5]
Research
(1) Quantum matter
WPI-SKCM2 Principal Investigator Kenta Kuroda, and Co-Principal Investigator Akio Kimura were corresponding authors on a study which developed a new piece of equipment: "an apparatus for laser-based spin and angle-resolved photoemission spectroscopy with micrometer spatial resolution (µ-SARPES)".[6] This technology enables scientists "to probe spatially-resolved electronic structures and vector information of spin polarization in three dimensions".[6]
(2) Particle/nuclear physics & cosmology
Project Professor at WPI-SKCM2 Muneto Nitta was a corresponding author on a study of pulsars.[7][8] The study gave rise to evidence that pulsar glitches are caused by superfluid vortices, creating "avalanches"[7][8]
(3) Soft matter and biological systems
The institute has undertaken investigations into the function of knotted topology in protein structures.[9] Using predicted protein structures provided by artificial intelligence, Principal Investigator Shang-Te Danny Hsu led a study on how the knotted topology in proteins assists in carrying out evolutionary conserved biological functions and provides mechanical stability for the protein structures[9]
(4) Pure and applied math
WPI-SKCM2 Project Professor Yuya Koda was a corresponding author on an article about positive flow-spines and contact 3-manifolds. [10] The article shows that the map from a set of isotopy classes of positive flow-spines of M to the set of isotopy classes of contact structures on M is surjective.[10] It also showed that any flow-spine can be deformed to a positive flow-spine by applying first and second regular moves one after the other. [10]
