Rolling tachyon and the Phase Space of Open String Field Theory
arXiv:2310.17895 · doi:10.1007/JHEP04(2025)129
Abstract
We construct the symplectic form on the covariant phase space of the open string field theory on a ZZ-brane in c=1 string theory, and determine the energy of the rolling tachyon solution, confirming Sen's earlier proposal based on boundary conformal field theory and closed string considerations.
