Arroyo, E. Aldo [UNESP]2014-05-202014-05-202010-11-05Journal of Physics A-mathematical and Theoretical. Bristol: Iop Publishing Ltd, v. 43, n. 44, p. 16, 2010.1751-8113http://hdl.handle.net/11449/24120We study a new set of identity-based solutions to analyze the problem of tachyon condensation in open bosonic string field theory and cubic superstring field theory. Even though these identity-based solutions seem to be trivial, it turns out that after performing a suitable gauge transformation, we are left with the known Erler-Schnabl-type solutions which correctly reproduce the value of the D-brane tension. This result shows explicitly that a seemingly trivial solution can generate a non-trivial configuration which precisely represents the tachyon vacuum.16engArtigo10.1088/1751-8113/43/44/445403WOS:000283300800027Acesso restrito
