1. Closed string symmetries in open string field theory: tachyon vacuum as sine-square deformation / Kishimoto, Isao ; Kitade, Tomomi ; Takahashi, Tomohiko
We revisit the identity-based solutions for tachyon condensation in open bosonic string field theory (SFT) from the viewpoint of the sine-square deformation (SSD). [...]

2. Vector profile and gauge invariant observables of string field theory solutions for constant magnetic field background / Ishibashi, Nobuyuki ; Kishimoto, Isao ; Masuda, Toru ; Takahashi, Tomohiko
We study profiles and gauge invariant observables of classical solutions corresponding to a constant magnetic field on a torus in open string field theory. [...]

3. Super Yang–Mills action from WZW-like open superstring field theory including the Ramond sector / Asada, Mitsuru ; Kishimoto, Isao
In the framework of WZW-like open superstring field theory (SSFT) including the Ramond (R) sector whose action was constructed by Kunitomo and Okawa, we truncate the string fields in both the Neveu–Schwarz (NS) and R sectors up to the lowest massless level and obtain the ten-dimensional super Yang–Mills (SYM) action with bosonic extra term by explicit calculation of the SSFT action. [...]

4. String field theory solution corresponding to constant background magnetic field / Ishibashi, Nobuyuki ; Kishimoto, Isao ; Takahashi, Tomohiko
Following the method recently proposed by Erler and Maccaferri, we construct solutions to the equation of motion of Witten's cubic string field theory, which describe a constant magnetic field background. [...]

5. Open string fields as matrices / Kishimoto, Isao ; Masuda, Toru ; Takahashi, Tomohiko ; Takemoto, Shoko
We show that the action expanded around Erler–Maccaferri's D-brane solution describes the D-brane system where one D-brane disappears due to tachyon condensation. [...]
