In this paper, Madelung’s quantum Euler equations will be re-derived, which will be shown to lead to the familiar form of the acoustic wave equation for a medium. A model of the density variation in the vacuum field around the nucleus of the hydrogen atom is then introduced and used to create a simplified representation of the atom in COMSOL. The time-independent form of the acoustic wave equation (Helmholtz equation) is used to find the eigenfrequency acoustic modes of the simulated atom. The analysis technique for the single atom case is extended to build a model of molecular hydrogen, and the numerical analysis results are presented and discussed. The paper concludes with some speculative discussion on the nature and make up of the dynamic vacuum medium being modeled around the hydrogen nucleus. This polar form of the Schrödinger equation can be separated into its real and imaginary parts respectively:

A vacuum test campaign evaluating the impulsive thrust performance of a tapered radio-frequency test article excited in the transverse magnitude 212 mode at 1937 MHz has been completed. The test campaign consisted of a forward thrust phase and reverse thrust phase at less than 8×10−6 torr vacuum with power scans at 40, 60, and 80 W. The test campaign included a null thrust test effort to identify any mundane sources of impulsive thrust; however, none were identified. Thrust data from forward, reverse, and null suggested that the system was consistently performing with a thrust-to-power ratio of 1.2±0.1 mN/kW.

This paper will discuss the current viewpoint of the vacuum state and explore the idea of a “natural” vacuum as opposed to immutable, non-degradable vacuum. This concept will be explored for all primary quantum numbers to show consistency with observation at the level of Bohr theory. A comparison with the Casimir force per unit area will be made, and an explicit function for the spatial variation of the vacuum density around the atomic nucleus will be derived. This explicit function will be numerically modeled using the industry multi-physics tool, COMSOL, and the eigenfrequencies for the n = 1 to n = 7 states will be found and compared to expectation.

... However, there is no similar equation in nonrelativistic physics for classical waves propagating with speeds lower than the speed of light. Previous attempts to use different forms of the Schrödinger equation to describe the propagation of classical waves were made [19][20][21][22][23], but the resulting equations were not fundamental. Therefore, the main aim of this paper is to derive such an equation by following the recent work [24] in which a new asymmetric wave equation was discovered, and used to formulate a theory of cold dark matter [25]. ...

... Therefore we conceive the dynamic vacuum as a real dissipative dielectric medium, as originally proposed by Weisskopf and Pauli in 1934 [29] with a gauge breaking vacuum electric density currents J, whose divergence is propor- We assume that the electric density oscillations defined in (8) propagates with variable light speed velocity and we will interpret them as De Broglie matter waves similar to classical pressure waves, in analogy with an approach suggested in a recent paper [30]. We note that the De Broglie hypothesis and the associated wave-particle dualism was the main motivation which inspired Schrodinger to discover his celebrated equation, which being a diffusive one typical of thermal Our proposal is similar to a recent proposal called vacuum texture theory [32], since it implements a new realistic interpretation of quantum wavefunctions (interpreting them as real De Broglie thermal waves), but differently from it assumes time dependent temperature fluctuations as those experimentally observed in laser physics [33]; we will suppose that they induce time dependent energy shifts in accelerated quantum particles that might be revealed in experiments as thermal noise and might be useful to justify the Born rule by our generalization of De Broglie-Bohm Quantum theory (as recently suggested in [34]). ...
