The effect of chemical potential on imaginary potential and entropic force

TL;DR

This paper investigates how chemical potential influences the imaginary potential and entropic force in heavy quarkonium melting, revealing that increased chemical potential reduces dissociation length via holographic duality.

Contribution

It provides a novel analysis of chemical potential effects on quarkonium dissociation mechanisms using AdS/CFT correspondence.

Findings

Chemical potential decreases dissociation length for both mechanisms.

Both imaginary potential and entropic force are similarly affected by chemical potential.

The study enhances understanding of quarkonium behavior in dense media.

Abstract

Imaginary potential and entropic force represent different mechanisms for melting the heavy quarkonium. In this paper, we study the chemical potential effect on these two quantities with respect to a moving quarkonium from the AdS/CTF duality. We observe that for both mechanisms the chemical potential has the same effect: the presence of the chemical potential tends to decrease the dissociation length.
