Entropic destruction of heavy quarkonium with hyperscaling violation
Abstract
We study the entropic destruction of heavy quarkonium in strongly coupled theories with an anisotropic scaling symmetry in time and a spatial direction. We consider Lifshitz and hyperscaling violation theories, which are covariant under a generalized Lifshitz scaling symmetry with the dynamical exponent z and hyperscaling violation exponent $ \theta$ . It is shown that the entropic force depends on the parameters of these theories. In particular, increasing z decreases the entropic force, thus reducing the quarkonium dissociation, while increasing $ \theta$ has the opposite effect. * Supported by the Innovation Fund of Key Laboratory of Quark and Lepton Physics (QLPL2020P01)
