From the AdS/CFT correspondence, the effects of charge and finite ’t Hooft coupling correction on the thermal width of a heavy quarkonium are investigated. To study the charge effect, we consider Maxwell charge which is interpreted as quark medium. In the case of finite ’t Hooft coupling corrections, $${\mathcal {R}}^4$$R4 terms and Gauss–Bonnet gravity have been considered, respectively. It is shown that these corrections affect the thermal width. It is also argued that by decreasing the ’t… 

The Imaginary Potential and Thermal Width of Moving Quarkonium from Holography

We study the effect of finite 't Hooft coupling corrections on the imaginary potential and the thermal width of a moving heavy quarkonium from the AdS/CFT correspondence. To study these corrections,

By the use of the gauge/gravity duality, we calculate the imaginary part of heavy quarkonium potential and thermal width with the effect of gluon condensate which is absent in $$\hbox {AdS}_{{5}}$$

We use gauge/gravity duality to investigate the effect of thermal fluctuations on the dissociation of the quarkonium meson in strongly coupled $(3+1)$-dimensional gauge theories. This is done by

Entropic destruction of a moving heavy quarkonium

Recently it has been shown that the peak of the quarkonium entropy at the deconfinement transition is related to the emergent entropic force which destructs the quarkonium. Using the AdS/CFT

Effects of the hyperscaling violation and dynamical exponents on the imaginary potential and entropic force of heavy quarkonium via holography

The imaginary potential and entropic force are two important different mechanisms to characterize the dissociation of heavy quarkonia. In this paper, we calculate these two quantities in strongly

Fate of in-medium heavy quarks via a Lindblad equation

A bstractWhat is the dynamics of heavy quarks and antiquarks in a quark gluon plasma? Can heavy-quark bound states dissociate? Can they (re)combine? These questions are addressed by investigating a

Holographic computation of Wilson loops in a background with broken conformal invariance and finite chemical potential

In this paper, we follow a `bottom-up' AdS/QCD approach to holographically probe the dynamics of a moving $q\bar{q}$ pair inside a strongly coupled plasma at the boundary. We consider a deformed

Configuration entropy for quarkonium in a finite density plasma

In the recent years many examples appeared in the literature where the configuration entropy (CE), introduced by Gleiser and Stamatopoulos, plays the role of an indicator of stability of physical
