Keio University


Established in 1858 by prominent educator and intellectual Yukichi Fukuzawa, Keio University is Japan’s oldest private institution of higher learning. A comprehensive research university, Keio values the pursuit of knowledge through jitsugaku, or empirical science — a concept developed by Fukuzawa that emphasizes applying reason, observation and verification in the search for practical solutions to society’s needs.

Following in his footsteps, Keio University is pioneering the globalization of education in Japan and the establishment of a preeminent center of research and innovation in the world. It has launched a university-wide initiative to spearhead research in the areas of longevity, security and creativity, which will enable people to live better, longer and safer lives.

A global player, Keio University ranked 9th in the Times Higher Education Alma Mater Index: Global Executives 2013 and 36th in the QS Graduate Employability Rankings 2016. It scored among the top 60 universities globally, and the top 10 in Asia, in the 2015 Reuters innovation metric. And Keio University came out on top in a 2015 survey of Japanese university brands by Nikkei BP Consulting.

Every year, Keio University School of Medicine awards the Keio Medical Science Prize, a prestigious award conferred to outstanding researchers in the medical and life sciences. Seven winners of the Keio Medical Science Prize have gone on to become Nobel laureates.

Keio University has more than 33,000 students representing 70 countries and 2,250 full-time faculty. Spread across 6 campuses in the Tokyo region are 10 undergraduate schools and 14 graduate schools.

Keio offers 14 degree programs in English and 26 double-degree programs with international partner institutes. Its wider global network of collaborators includes 300 overseas institutions in 49 countries. Its alumni body is 350,000 strong, connected via 800 domestic and 70 overseas voluntary organizations called Mita-kai. Notable alumni include three prime ministers, two astronauts, and many Olympians and Paralympians.

Defying the laws of attraction

Competing forces can flip the electromagnetic field that exists between conductive plates in a vacuum.

The Casimir effect is an attractive or repulsive electromagnetic force between two conductive, uncharged, plates set nanometres apart in a vacuum. The strength and direction of the force is usually dependent on the shape and position of the plates.

A team including researchers from Keio University wanted to know whether they could flip the force direction without moving the plates. They modelled a chain of fermions — elementary particles, such as electrons, that cannot occupy the same position in space — between two fixed plates in a vacuum. Increasing the pressure squashed the fermions together and forced them to interact or ‘couple’ with each other.

The team calculated a tipping point when the Casimir effect flips from attractive to repulsive, resulting from the competition between the attractive force of the Casimir effect and the repulsive force generated by the interacting fermions.
