  To better understand the effects of strong coupling and QCD at high
temperature in QGP, by using holographic model, we investigate the dissociation
effect of bottomonium under the higher-order curvature corrections to the
supergravity action corresponding to the corrections of large N expansion of
boundary CFT in the side of field theory. The results show that effective
potential is not a good physical quantity to estimate the dissociation strength
of bottomonium in the case of finite wave number and considering the
higher-order curvature corrections. Therefore, we calculate the quasinormal
spectra(QNMs) and the differential configuration entropy(DCE). It is found that
the dissociation effect is stronger for the stronger coupling.
