1-1 Machikaneyama, Toyonaka, Osaka 560-0043
Research Interests:

  Harmony among various subjects of theoretical physics. D-brane physics in string theory. Elementary particle physics, Hadron physics, Nuclear physics, Condensed matter physics, Cosmology, Astrophysics.

  Specifically: AdS/CFT correspondence, Holographic QCD, String field theory, Tachyon condensation, M-theory, Solitons in field theories, Non-commutative spaces, String dualities, etc.

  Brane physics itself is a central concept in theoretical physics. It leads to possible non-perturbative formulations of string/M theory, and relates superstring theory with various other subjects in physics.
