Abstract

jats:titleAjats:scbstract</jats:sc> </jats:title>jats:pWe construct novel black strings that are neither time-translation invariant, nor axisymmetric, nor translationally invariant in the string direction, but nevertheless have a helical Killing vector field. These solutions branch from the superradiant instability of jats:italicD</jats:italic> = 6 Myers-Perry black strings with equal angular momenta. We coin these solutions as jats:italicblack resonator strings</jats:italic> and we find that they have more entropy than Myers-Perry black strings for the energies and angular momenta where both solutions coexist. We also construct Kaluza-Klein geons, which share the symmetries of black resonator strings, but are horizonless. Unlike in other superradiant systems, Kaluza-Klein geons are not the horizonless limit of black resonator strings and are instead entirely separate solutions.</jats:p>
