Molecular analogue for scalar dynamics in an AII metric
Tachyons are hypothetical particles that propagate faster than light, yet they have never been observed in nature or in the laboratory. In this work, we introduce the $H_2^+$ molecule as an analogue for the dynamics of a spinless test particle interacting with the gravitational field generated by a tachyon. The tachyonic spacetime is modeled using an AII metric, and the problem is analyzed through the Klein--Gordon equation for a scalar field in this background. We compute the quasi-normal modes and the Hawking radiation spectrum associated with the system. By introducing a specific external potential --- defined precisely for this purpose and fine--tuned through a careful comparison of system constants --- we demonstrate that both the radial and angular components of a test particle's wave function can be effectively reproduced by the electronic dynamics within $H_2^+$. We thus propose a mathematical framework for studying a molecular analog model of an extreme gravitational system.
