AINS paper entitled: "On the Thermodynamic Origin of the Quantum Potential", Physica A 388 (2009) 811-823.
See also quant-ph/arXiv:0808.3539.
Abstract: The quantum potential is shown to result from the presence of a subtle thermal vacuum energy distributed across the whole domain of an experimental setup. Explicitly, its form is demonstrated to be exactly identical to the heat distribution derived from the defining equation for classical diffusion-wave fields. For a single free particle path, this thermal energy does not significantly affect particle motion. However, in between different paths, or at interfaces, the accumulation-depletion law for diffusion waves provides an immediate new understanding of the quantum potential's main features.
Derivation of the Exact Schrödinger Equation
AINS-paper entitled "The Vacuum Fluctuation Theorem: Exact Schrödinger Equation via Nonequilibrium Thermodynamics" Phys. Lett. A 372 (2008) 4556-4563.
Abstract: By assuming that a particle of energy hbar.omega is actually a dissipative system maintained in a nonequilibrium steady state by a constant throughput of energy (heat flow), the exact Schroedinger equation is derived, both for conservative and nonconservative systems. Thereby, only universal properties of oscillators and nonequilibrium thermostatting are used, such that a maximal model independence of the hypothesised sub-quantum physics is guaranteed. It is claimed that this represents the shortest derivation of the Schroedinger equation from (modern) classical physics in the literature, and the only exact one, too. Moreover, a "vacuum fluctuation theorem" is presented, with particular emphasis on possible applications for a better understanding of quantum mechanical nonlocal effects.

A New Derivation of the Schrödinger Equation (2004)
AINS-paper entitled "From Classical Hamiltonian Flow to Quantum Theory: Derivation of the Schrödinger Equation" published in Foundations of Physics Letters 17, 4 (2004) 343-362.
Abstract: It is shown how the essentials of quantum theory, i.e., the Schrödinger equation and the Heisenberg uncertainty relations, can be derived from classical physics. Next to the empirically grounded quantisation of energy and momentum, the only input is given by the assumption of fluctuations in energy and momentum to be added to the classical motion. Extending into the relativistic regime for spinless particles, this procedure leads also to a derivation of the Klein-Gordon equation. Comparing classical Hamiltonian flow with quantum theory, then, the essential difference is given by a vanishing divergence of the velocity of the probability current in the former, whereas the latter results from a much less stringent requirement, i.e., that only the average over fluctuations and positions of the average divergence be identical to zero.

The dotted lines (right) indicate symbolically that the waves pictured represent only the local surroundings of a generally extending undulatory probability field, thus illustrating that the fluctuations are to be seen in the context of the whole (nonlocal) environment.

TIME'S ARROW: IRREVERSIBILITY FROM QUANTUM SYSTEMS TO BIOLOGICAL EVOLUTION
A Symposium as part of EMCSR 2000 - University of Vienna / Main Building, April 25 - 28, 2000.
Most of the fundamental laws in the natural sciences are formulated as time-symmetric ones, thereby reflecting the conception from classical dynamics of time as a mere parameter. A notable exception is the Second Law of thermodynamics, which introduces an arrow of time into physics. Although this law states that the entropy in a closed system can only remain constant or increase, but never decrease, its relation to other areas of the natural sciences has not been very clear.
In particular, there exist two areas "adjacent" to thermodynamics, which at first sight seem to largely oppose the Second Law, albeit for different reasons. On the one hand, quantum theory is characterized by time-symmetric fundamental equations (like the Schrödinger equation or some relativistic analogue thereof). On the other hand, biological evolution has recently been shown to exhibit features of time- symmetric "punctuated equilibrium" behavior. Still, evolution might generally have to be characterized by a progressive trend of increasing order. However, even this time-asymmetry apparently would be in opposition to the entropy law.
In this symposium, we intend to collect evidence for an arrow of time in the fields just mentioned, i. e., quantum theory and evolutionary biology. For, contrary to widespread belief, the solutions to the fundamental equations of quantum theory do show time irreversible behavior due to a breaking of their inherent symmetries. Similarly, irreversibility also characterizes laboratory experiments and computer models of biological evolution. So, we are confronted with the scenario that in both fields some fundamental laws may be time-symmetric, while any concrete systemic behavior generally is not, because it represents an emergent phenomenon.
Ideally, participants could compare the latter with more general (thermodynamic or other) considerations to enquire whether the concepts of irreversibility in the quantum and biological domains, respectively, are radically different, or whether they share common, perhaps basic, systemic characteristics.

Serious Matter: The John-Bell – Scandal
Abstract: In a festive lecture at the University of Vienna in 1987, on the occasion of Erwin Schrödinger’s 100th birthday, the famous physicist John Bell complained about the “scandal” (literally) that the so-called “deBroglie-Bohm interpretation” (BBI) of quantum theory was not taught at the universities and treated on an equal footing with the predominant “Copenhagen interpretation”. On the contrary, over decades, and up to the present day, the BBI has almost always been marginalized or grossly misrepresented by leading quantum physicists.
Actually, John Bell devoted practically all of his papers on quantum theory to the implications around the BBI, as can easily be seen from the collection of said papers in his book on “Speakable and Unspeakable in Quantum Mechanics”. Now, in November 2000, a symposium was held at the University of Vienna on the occasion of the 10th anniversary of Bell’s death. Physicists were invited to talk at this symposium who only recently had published utterly wrong “arguments” calling for the dismissal of the BBI. However, not a single exponent of the BBI was to give a talk, although the symposium was performed in the name of John Bell. Thus, the scandal is being prolonged.
Moreover, the series of (often provably intentional) misrepresentations of the BBI is continued in articles celebrating “100 years of quantum theory”….
