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…

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…

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…
