Patient-practitioner-remedy (PPR) entanglement. Part 2: Extending the metaphor for homeopathy using molecular quantum theory.

A quantum metaphor developed previously for homeopathy, involving triadic patient-practitioner-remedy (PPR) entanglement, is extended by importing concepts used in chemistry to describe the electronic structures of molecules. In particular, the electronic energy states of triangular tri-atomic molecules are used metaphorically to predict that (a) the more a homeopathic medicine is potentised, the deeper the level of cure is likely to be, and (b) the practitioner can be included as a beneficiary of the therapeutic process. The model also predicts that remedy attenuation and degree of PRR interaction could (in the quantum theoretical sense) represent a pair of complementary conjugate variables.

Quantum theory of optical stochastic cooling.

Quantum theory of optical stochastic cooling is presented. Results include a full quantum analysis of the interaction of the beam with radiation in the undulators and in the quantum amplifier. A density matrix of the whole system is constructed and the cooling rate is evaluated. It is shown that quantum fluctuations change classical results of stochastic cooling at low bunch population and set a limit on the cooling rate.

[Boltzmann's principle and Einstein's first quantum theories].

The crucial role played by statistical mechanics in Einstein's work on quantum theory has been repeatedly stressed. Nevertheless, in this paper we argue that Einstein's attitude to Boltzmann's principle was more complex than is usually understood. In fact, there are significant differences and nuances that in our opinion have yet to be sufficiently considered, in the various interpretations and uses Einstein made of this principle in his work on quantum theory, more specifically between 1905 and the First Solvay Conference, in 1911.

NMR and relative quantum theory.

Assumptions on which NMR dynamical studies have been based for nearly 50 years are consistent with a relative quantum theory based on Minkowski spacetime. A symmetry condition required by the existence of reference frames takes over the usual role of particle permutation symmetry, leaving a quantum theory of relative motion which only involves observables.

[The concepts of quantum theory can be introduced into psychophysiology].

There are some ideas in the quantum mechanics, which may be assimilated by psychophysiology. The concept of interference alternatives, advanced by Richard Feynman, may extend the subject matter of the notion of need. The quantum theory assumes virtual transitions. The idea of the physical virtual process may be the rational basis for subjective reality.

Patient-practitioner-remedy (PPR) entanglement. Part 6. Miasms revisited: non-linear quantum theory as a model for the homeopathic process.

The possibility that non-linear quantum theory could be used to model PPR entanglement is discussed in relation to the treatment of miasms. In this model, miasms are imagined as disease entities behaving like solitary waves, or 'solitons' which, when trapped in a therapeutic state space, requiring equally soliton-like (miasmatic or high potency) remedies to effectively 'annihilate' them.

Application of the quantum theory of atoms in molecules to selected physico-chemical and biophysical problems: focus on correlation with experiment.

This article reviews how the quantum theory of atoms in molecules (QTAIM) can be used to predict experimental physico-chemical properties of molecules of biologic interest: the amino acids, the polycyclic aromatic hydrocarbons (PAH), and the opiates, for example, morphine and PEO. The predicted experimental properties are as diverse as the partial molar volumes, the free energies of hydration, the second code-letter in the genetic code, the resonance energies, and the proton spin-spin coupling constants. Recent examples of the utilization of QTAIM to construct excellent statistical models (with squared correlation coefficients (r(2)) > 0.9) correlating properties of the electron density and of the pair density to experiment are reviewed. Some new results on the solvent effects on electron delocalization are also presented.

Quantum theory of light and noise polarization in nonlinear optics.

We present a consistent quantum theory of the electromagnetic field in nonlinearly responding causal media, with special emphasis on Chi(2) media. Starting from QED in linearly responding causal media, we develop a method to construct the cubic Hamiltonian expressed in terms of the complex nonlinear susceptibility in a quantum mechanically consistent way. In particular, we show that the method yields the nonlinear noise polarization, which together with the linear one is responsible for intrinsic quantum decoherence.

Quantum theory of spin dynamics of exciton-polaritons in microcavities.

We present the quantum theory of momentum and spin relaxation of exciton-polaritons in microcavities. We show that giant longitudinal-transverse splitting of the polaritons mixes their spin states, which results in beats between right- and left-circularly polarized photoluminescence of microcavities, as was recently experimentally observed [Phys. Rev. Lett. 89, 077402 (2002)]]. This effect is strongly sensitive to the bosonic stimulation of polariton scattering.

Quantum theory of spontaneous emission by real moving atoms.

We outline the solution of a fundamental problem in quantum theory which has hitherto lacked a proper solution, namely, finding the requisite quantum theoretical framework guaranteeing that the calculated inverse spontaneous emission rate of a moving atom, as a composite system of charged particles interacting with the Maxwell field, is slowed down exactly as in time dilation.

Entanglement model of homeopathy as an example of generalized entanglement predicted by weak quantum theory.

Homeopathy is scientifically banned, both for lack of consistent empirical findings, but more so for lack of a sound theoretical model to explain its purported effects. This paper makes an attempt to introduce an explanatory idea based on a generalized version of quantum mechanics (QM), the weak quantum theory (WQT). WQT uses the algebraic formalism of QM proper, but drops some restrictions and definitions typical for QM. This results in a general axiomatic framework similar to QM, but more generalized and applicable to all possible systems. Most notably, WQT predicts entanglement, which in QM is known as Einstein-Podolsky-Rosen (EPR) correlatedness within quantum systems. According to WQT, this entanglement is not only tied to quantum systems, but is to be expected whenever a global and a local variable describing a system are complementary. This idea is used here to reconstruct homeopathy as an exemplification of generalized entanglement as predicted by WQT. It transpires that homeopathy uses two instances of generalized entanglement: one between the remedy and the original substance (potentiation principle) and one between the individual symptoms of a patient and the general symptoms of a remedy picture (similarity principle). By bringing these two elements together, double entanglement ensues, which is reminiscent of cryptographic and teleportation applications of entanglement in QM proper. Homeopathy could be a macroscopic analogue to quantum teleportation. This model is exemplified and some predictions are derived, which make it possible to test the model.

Environmental management: principles from quantum theory.

Management of the environment is a critical role component for any health care provider. Turmoil, multiple relationships, and new ways of "doing business" characterize today's health care system, and traditional management techniques, based on Newtonian physics may no longer be effective. Principles helpful for managing the current health care environment may be found in quantum theory. These include (1) the world is unpredictable; (2) the intent of the observer influences how the world is seen; and (3) interrelationships are what count, not the things themselves. These principles are derived from the work of Wheatley, who applied the quantum theoretical framework to leadership. Strategies for gaining competence in managing the new environment are explored. Such strategies include shared governance, the process of delegation, and coordination of services. These strategies may be helpful to colleagues in education as well as in practice.
