  We study the dissociation of heavy vector mesons in a thermal medium from the
point of view of the configurational entropy. Bottomonium and charmonium vector
mesons in a plasma are represented using a holographic AdS/QCD model. The
quasinormal modes, describing the quasiparticle states, are determined for a
representative range of temperature and the corresponding CE is then computed.
The main result indicates that the CE is an important contrivance to
investigate the stability of the heavy mesons against dissociation in the
thermal medium.
