DESCRIPTION:Title: <a href="https://researchseminars.org/talk/FHD3/4/">Gen
 eralized 3D instanton crystals</a>\nby Matti Jarvinen (APCTP) as part of F
 rontiers of Holographic Duality-3\n\n\nAbstract\nNuclear matter at large n
 umber of colors is necessarily in a solid phase. In particular holographic
  nuclear matter takes the form of a crystal of instantons of the flavor gr
 oup. I analyze the three-dimensional crystal structures and the orientatio
 n patterns for the two-body potential motivated by holographic duality. I 
 use simulations of large ensembles of instantons to identify the lattice s
 tructure and orientations for various parameter values of the two-body pot
 ential. The resulting phase diagram is surprisingly complex\, including a 
 variety of ferromagnetic and antiferromagnetic crystals with various globa
 l orientation patterns\, and various "non-Abelian" crystals where orientat
 ions have no preferred direction. The simulation results are augmented by 
 analytic analysis of the long-distance divergences\, and numerical computa
 tion of the (divergence free) energy differences between the non-Abelian c
 rystals\, which precisely determine the structure of the phase diagram.\n
