Gregory-Laflamme-type instability of boson strings and related phases in D = 5 Kaluza-Klein theory

Abstract We add an S 1 extra dimension (size L) to the well known D = 4 static, spherically symmetric Q-balls and boson stars. We show that the resulting uniform horizonless boson strings possess a static zero-mode for a critical value of L. This is at the threshold of a Gregory-Laflamme instability...
