Singular field redefinition between Witten's string field theory and Witten's theory deformed by Ellwood invariant
Yuji Ando
We construct a field redefinition between Witten's string field theory and its deformation by the Ellwood invariant. This field redefinition is singular and does not imply physical…
Fast-forward scaling theory for quantum dynamics on curved space-time
Yuji Ando, Shumpei Masuda
Scaling properties inherent in quantum dynamics have been studied for various systems in terms of acceleration, deceleration and time reversing. We show a scaling property of quant…
Closed string amplitudes around tachyon vacuum solution in Kaku theory
Yuji Ando
We incorporate closed string field into Kaku's open string field theory which is defined by using Kaku vertex, and we construct open-closed string field theory. To do this, we defi…
A consistent light-cone-gauge superstring field theory
Yuji Ando, Ryota Fujii, Hiroshi Kunitomo +1
Extending a recent development in the bosonic string field theory, we construct a map from the Witten-type gauge-invariant superstring field theory based on an structu…
