Specifically, we show that an exponential multitude of classically stable "halo" bound states can be formed between large finite temperature D4-D0 black hole cores and much smaller, arbitrarily charged black holes at the same temperature. We map out in full the regions of existence for thermodynamically stable and metastable bound states in terms of the core's charges and temperature, as well as the region of stability of the core itself. Several features of these systems, such as a macroscopic configurational entropy and exponential relaxation timescales, are similar to those of the extended family of glasses. We draw parallels between the two with a view toward understanding complex systems in fundamental physics. en_US dc.description.sponsorship Physics en_US dc.language.iso en_US en_US dc.publisher Springer Verlag en_US dc.relation.isversionof doi://10.1007/JHEP01(2012)003 en_US dc.relation.hasversion http://arxiv.org/abs/1108.5821 en_US dash.license OAP dc.subject black holes in string theory en_US dc.subject holography and condensed matter physics en_US dc.subject high energy physics en_US dc.title Hot Halos and Galactic Glasses (Carbonado) en_US dc.type Journal Article en_US dc.description.version Accepted Manuscript en_US dc.relation.journal Journal of High Energy Physics en_US dash.depositing.author Denef, Frederik dc.date.available 2012-03-05T17:36:47Z
