Nanofilm thickness measurement by resonant frequencies

Abstract

We study (p, q) = (2, 4k) minimal superstrings within the minimal superstring field theory constructed in hep-th/0611045. We explicitly give a solution to the W 1+∞ constraints by using charged D-instanton operators, and show that the (m, n)-instanton sector with m positive-charged and n negative-charged ZZ-branes is described by an (m + n) × (m + n) supermatrix model. We argue that the supermatrix model can be regarded as an open string field theory on the multi ZZ-brane system.
