 氏（米子高専）\n\n題目 : Dissipation in the 1/D expansion for pla
 nar matrix models\nアブストラクト：We consider the thermal behavio
 r of a large number of matrix degrees of freedom in the planar limit. We w
 ork in 0+1 dimensions\, with D matrices\, and use 1/D as an expansion para
 meter. This can be thought of as a non-commutative large-D vector model\, 
 with two independent quartic couplings for the two different orderings of 
 the matrices. We compute a thermal two-point correlator to O(1/D) and find
  that the degeneracy present at large D is lifted\, with energy levels spl
 it by an amount ∼1/D ​. This implies a timescale for thermal dissipati
 on ∼D​. At high temperatures dissipation is predominantly due to one o
 f the two quartic couplings.\n\nhttps://indico.nitep.omu.ac.jp/event/183/
