In the case of heavy quarks the light-front holographic equations reduce to a nonrelativis- tic Schr¨ odinger equation in configuration space with potential

where V$_{conf}$ for a soft-wall dilaton background is the potential for a three-dimensional har- monic oscillator, V$_{conf}$ ≃ 1 $_{2}$m$_{red}$ ω $^{2}$r$^{2}$. Here m$_{red}$ is the reduced mass of the heavy Q − Q
