High energy scattering of non-critical strings
Kenichiro Aoki, Eric D'Hoker
We summarize recent work, in which we consider scattering amplitudes of non-critical strings in the limit where the energy of all external states is large compared to the string te…
Non-critical strings at high energy
Kenichiro Aoki, Eric D'Hoker
We consider scattering amplitudes in non-critical string theory of external states in the limit where the energy of all external states is large compared to the string tension.…
Renormalization group and critical behaviour in gravitational collapse
Takashi Hara, Tatsuhiko Koike, Satoshi Adachi
We present a general framework for understanding and analyzing critical behaviour in gravitational collapse. We adopt the method of renormalization group, which has the following a…
Compact hyperbolic universe and singularities
Akihiro Ishibashi, Tatsuhiko Koike, Masaru Siino +1
Recently many people have discussed the possibility that the universe is hyperbolic and was in an inflationary phase in the early stage. Under these assumptions, it is shown that t…
The Aharonov-Bohm scattering : the role of the incident wave
S. Sakoda, M. Omote
The scattering problem under the influence of the Aharonov-Bohm (AB) potential is reconsidered. By solving the Lippmann-Schwinger (LS) equation we obtain the wave function of the s…
