We analyze exactly the simplest minimal superstring theory, using its dualmatrix model. Its target space is one dimensional (the Liouville direction),and the background fields include a linear dilaton, a possible tachyoncondensate, and RR flux. The theory has both charged and neutral branes, andthese exhibit new and surprising phenomena. The smooth moduli space of chargedbranes has different weakly coupled boundaries in which the branes havedifferent RR charges. This new duality between branes of different chargesshows that the semiclassical notion of localized charge is not precise in thequantum theory, and that the charges of these branes can fluctuate.Correspondingly, the RR flux in some parts of target space can also fluctuate-- only the net flux at infinity is fixed. We substantiate our physical picturewith a detailed semiclassical analysis of the exact answers. Along the way, weuncover new subtleties in super-Liouville theory.Comment: 46 pages, 3 figures, new identities for the neutral brane, references added, minor change
