Abstract
We show that adding quadratic temporal dispersion to a dynamic-vacuum acoustic model yields a fully analytic, exactly isospectral mapping to the hydrogenic Coulomb problem. In the regime with , a proton-imprinted constitutive profile produces an inverse sound speed and hence a time-harmonic operator that is Coulombic at each bound eigenfrequency. Separation of variables yields the exact hydrogenic eigenfunctions ; the angular labels emerge naturally from the Laplace-Beltrami spectrum on via rotational symmetry and boundary conditions (as in standard quantum mechanics), while localization follows from in a reactive stop band consistent with causal, passive dispersion. While angular-momentum quantization follows directly from rotational symmetry and boundary conditions in standard quantum mechanics (consistent with Noether's theorem), here it emerges within a classical-like dispersive acoustic framework without introducing additional wave-mechanical postulates beyond symmetry and self-adjointness. This highlights dispersion's role in bridging a hydrodynamic description to quantumlike spectral structure. Identifying maps spatial scale to frequency, giving and reproducing the Rydberg ladder. Calibration to the reduced-mass Rydberg frequency () fixes and , with no free parameters. We determine the frequency dependence of and consistent with the underlying dispersive physics and demonstrate agreement with hydrogenic mode shapes and transition lines. The framework also predicts isotope shifts and symmetry-respecting Stark/Zeeman analogues. Dispersion thus renders quantization an emergent consequence of symmetry, boundary conditions, and causal response in a dynamic vacuum.

- The Madelung/Bogoliubov linearization refers to expressing the Schrödinger or Gross-Pitaevskii equation in hydrodynamic form (via Madelung's transformation) and then linearizing about a uniform background density to obtain small-amplitude wave equations. This procedure yields the Bogoliubov dispersion relation , where the first term corresponds to acoustic (phononlike) behavior and the second term arises from quantum-pressure effects. At low (long wavelengths), the first term dominates and gives acoustic behavior (); at high (short wavelengths or quantum-pressure-dominated regime), the second term dominates, yielding a quadratic dependence .

- In this construction, the coefficients and represent the effective response of the dispersive medium, analogous to the energy and Coulomb coupling terms in the hydrogenic Schrödinger equation. Because the medium is causal and frequency dependent, these coefficients vary with ; however, the physically relevant solutions occur only at discrete eigenfrequencies . Evaluating the coefficients at these eigenfrequencies and imposing ensures that the effective propagation constant is imaginary, corresponding to a bound (evanescent) spatial mode. Setting , independent of , keeps the coupling strength constant across all eigenstates. With these assignments, the radial equation reduces to the hydrogenic Coulomb equation. Thus, the quantized hydrogenic structure emerges naturally from the dispersive acoustic formulation without introducing it as an external assumption.
- The condition designates a reactive regime of the dispersive medium in which the effective squared wave number becomes negative, producing evanescent (spatially decaying) solutions rather than propagating waves. Physically, this corresponds to a stop band in which the stored reactive energy exceeds the kinetic component, confining the mode and creating a discrete bound state. In this sense, plays the same role as negative total energy in the Schrödinger formulation of hydrogen, marking the transition from continuum to bound eigenmodes.
