Solving Witten's string field theory using the butterfly state
Yuji Okawa
We solve the equation of motion of Witten's cubic open string field theory in a series expansion using the regulated butterfly state. The expansion parameter is given by the regula…

Some exact computations on the twisted butterfly state in string field theory
Yuji Okawa
The twisted butterfly state solves the equation of motion of vacuum string field theory in the singular limit. The finiteness of the energy density of the solution is an important…

Quantum aspects of Seiberg-Witten map in noncommutative Chern-Simons theory
Kirk Kaminsky, Yuji Okawa, Hirosi Ooguri
Noncommutative Chern-Simons theory can be classically mapped to commutative Chern-Simons theory by the Seiberg-Witten map. We provide evidence that the equivalence persists at the…
