Last but not least, it must be further investigated whether light manifests itself differently under different conditions. One of these manifestations is represented by an axisymmetric solution of the present theory, which has the nonzero angular momentum of a boson particle. Another is represented by a plane-polarized wave having zero angular momentum. 

Particles of integer spin (e.g., spin 1 or spin 0) are called bosons. Particles... 

As a result of the interaction between the molecule and the boson field, the bare molecule becomes dressed with a cloud of boson particles in the language of Sect. 2 the dressed molecule is an elementary excitation in the many-body system of molecules and boson particles. The number density of dressing boson particles is given by... 

Subject and relatedness - developments via fermion-boson, particle-wave, structure-phase, and processing-information dualities into the preliminary final destinations of matter and consciousness ontogenesis retracting (universe) phylogenesis. 

An instability-induced grand transition from quantum vacuum to material existence might have created our universe. Energy and entropy gradients mediated duality developments and transitions between fermions and bosons, particles and waves, structure and phase into the process-information dualities of life patterns. At the interface to the universe, life patterns developed a preliminary finite duality between existent matter and self-consciousness fields. By this grand transition a facility of awareness beyond space and time originated that transformed its theses/antitheses tensions into creativity. 

According to the Pauli principle, the complete wave function (including both space and spin coordinates) of a system of identical fermions (particles with halfintegral spin) must be antisymmetric with respect to interchange of any two fermions. The complete wave function of a system of identical bosons (particles with integral spin) must be symmetric with respect to interchange of any two bosons. 

The deuterium (D or H) contained in CD3 has nuclear spin 7=1 and belongs to the class of bosons (particles with integer value of spin) [88]. The Pauli principle... 

This equation has at least one advantage over the Schrodinger equation ct and x, y, z enter the equation on equal footing, whieh is required by special relativity. Moreover, the Fock-Klein-Gordon equation is invariant with respect to the Lorentz transformation, whereas the Schrodinger equation is not. This is a prerequisite of any relativity-consistent theory, and it is remarkable that such a simple derivation made the theory invariant. The invariance, however, does not mean that the equation is accurate. The Fock-Klein-Gordon equation describes a boson particle because vk is a usual scalar-type function, in contrast to what we will see shortly in the Dirac equation. 

The third volume highlights chemical reactivity through molecular structure, chemical bonding (introducing bondons as the quantum bosonic particles of the chemical field), localization from Hiickel to Density Functional expositions, especially how chemical principles of electronegativity and chemical hardness decide the global ehemieal reactivity and interaction ... 

The nucleons interact through their constituents, and their strong interaction can also be depicted as boson exchange. (All interaction quanta are bosons, i.e., particles with integer spins.) The strongly interacting bosons (particles with integer spins), which take part in the nucleon-nucleon interaction, are called mesons. These are n°, K", K°, K , ri°, p, p°, p ,... 

Hubbard Hamiltonians are model Hamiltonians describing the low-energy physics of interacting fermionic and bosonic particles in a lattice [105]. They have the general tight-binding form... 

The above discussion of the intermolecular potentials and of the stability of collision systems in reduced dimensionality provides the microscopic justification for studying an ensemble of polar molecules in two-dimensions interacting via (modified) dipole-dipole potentials. At low temperatures T < ficoj., the general many-body Hamiltonian has the form of Equation 12.5. As an example of the possibilities offered by potential engineering to realize novel many-body quantum phases, we here focus on bosonic particles interacting via the effective potential =D/p of Equation 12.6,... 

Finally, let me jump back to Chapter 1 on Bondons on Grapheme Nanoribbons with Topological Defectsin which novel features of the bosonic particle associated with the chemical bonding field - the bondon -recently created by Prof Putz to fulfill the particle-wave duality (another basal symmetry present in Nature) are disclosed. The existence of these... 

When properly interpreted, the Klein-Gordon equation gives quite satisfactory results for bosonic particles. However, there are reasons for rejecting it for the description of an electron. For instance, it does not accommodate the spin i nature of the electron. Furthermore, the occurrence of a second derivative with respect to time makes it difficult to introduce the notion of stationary states. To derive an alternative equation, Dirac" tried to find a Lorentz invariant equation of the form... 

It was actually chosen before the Higg Boson armouncement. One of the things that was interesting and just a little bit of inspiration was the search for the Higg Boson particle and the way that the particle changed the understanding of the universe and science. 

The B-E distribution applies to bosons (particles with integral spin) for which no restrictions are placed on the occupancy number. The negative 1 in the denominator allows the occupancy of the groimd state to get very large as T 0 which is known as Bose condensation. The transition of He to superfluid He-11 at 2.17 K (the so-called lambda transition) is an example of Bose condensation. 

The derivation of the ensembles presented in this section is completely general and also valid for quantum systems. However, it is not complete as quantum statistics of quantum particles such as photons, electrons, protons, etc., requires the additional consideration of fermionic and bosonic particle symmetries, respectively, in dependence of their particle spin. In all applications presented in this book, we only consider classical or semiclas-sical systems, where the quantum effects are hidden in the parametrization of the effective potentials used in the models. The assumption is that mesoscopic systems such as macromolecules and molecular aggregates behave sufficiently cooperatively to allow for the investigation of the net effect only, but not the individual quantum-mechanical...
