Wave-particle duality at Macro scale?


There are some new results from the walking droplets that demonstrate how wave-like statistics arise from an underlying pilot-wave dynamics through deterministic chaos.

The video is summarizing most of the stuff linked above. But what is the microscopic equivalent to the vibrating bath seen in droplet experiments? I've come across papers suggesting some form of "intrinsic periodicity" as per de Brogle's idea suggesting that inside the particle there was a periodic process that was equivalent to a clock. Donatello Dolce has published a few papers on this topic, but I haven't seen it much discussed elsewhere:
We interpret the relativistic quantum behavior of elementary particles in terms of elementary cycles. This represents a generalization of the de Broglie hypothesis of intrinsically “periodic phenomenon”, also known as “de Broglie internal clock”. Similarly to a “particle in a box” or to a “vibrating string”, the constraint of intrinsic periodicity represents a semi-classical quantization condition, with remarkable formal correspondence to ordinary relativistic quantum mechanics. In this formalism the retarded local variations of four-momentum characterizing relativistic interactions can be equivalently expressed in terms of retarded local modulations of de Broglie space-time periodicity, revealing a geometrodynamical nature of gauge interaction.

This is another paper by the Gerhard Grossing et al. group that uses some of the insights gained from the bouncing/walking droplets in the experiments of Couder's group to model certain QM phenomena:
In a new approach to explain double-slit interference "from the single particle perspective" via "systemic nonlocality", we answer the question of how a particle going through one slit can "know" about the state of the other slit. We show that this comes about by changed constraints on assumed classical sub-quantum currents, which we have recently employed to derive probability distributions and Bohm-type trajectories in standard double-slit interference on the basis of a modern, 21st century classical physics. Despite claims in the literature that this scenario is to be described by a dynamical nonlocality that could best be understood in the framework of the Heisenberg picture, we show that an explanation can be cast within the framework of the intuitively appealing Schrodinger picture as well. We refer neither to potentials nor to a "quantum force" or some other dynamics, but show that a "systemic nonlocality" may be obtained as a phenomenon that emerges from an assumed sub-quantum kinematics, which is manipulated only by changing its constraints as determined by the changes of the apparatus. Consequences are discussed with respect to the prohibition of superluminal signaling by standard relativity theory...

As we employ no "quantum force", therefore, we consider "systemic nonlocality" as a phenomenon that emerges from a sub-quantum kinematics, which is manipulated only by changing its constraints as determined by the changes of the apparatus. In fact, with our approach we have in a series of papers obtained essential elements of quantum theory. They derive from the assumption that a particle of energy E = ħω is actually an oscillator of angular frequency ω phase-locked with the zero-point oscillations of the surrounding environment, the latter of which containing both regular and fluctuating components and being constrained by the boundary conditions of the experimental setup via the buildup and maintenance of standing waves. The particle in this approach is an off-equilibrium steady-state maintained by the throughput of zero-point energy from its vacuum surroundings. This is in close analogy to the bouncing/walking droplets in the experiments of Couder's group, which in many respects can serve as a classical prototype guiding our intuition.
