Research Interests and Activities

In the last years I have concentrated on one project only: the elaboration of the microscopic tetron theory. It is a model for the substructure of Quarks and Leptons and actually a new Conception of the Universe, because it deals with many contemporary problems, from the understanding of fermion families and quark lepton masses and mixings to the problem of the accelerated expansion of the universe (dark energy). I have become so convinced of this approach that in the meantime I consider the whole physical reality through the glases of this model. Everything seems so clear and plausible now.

The main features of the microscopic theory can be described as follows:

I.

-Our universe is a 3-dimensional elastic substrate which once has condensed and now expands within some higher dimensional space (with dimension >=6).

-The elastic substrate is built from invisible 'tetron' constituents with bond length about the Planck length and binding energy the Planck energy.(*)

-All ordinary matter quarks and leptons are quasiparticle excitations gliding on the elastic tetron substrate.

-Since the quasiparticles fulfill Lorentz covariant wave equations, they perceive the universe as a 3+1 dimensional spacetime continuum lacking a preferred rest system.

-Any type of mass/energy induces curvature on the spacetime continuum as determined by the Einstein equations.

II.

-The 24 known quarks and leptons arise as excitations of a tetrahedral fiber structure, which is made up from 4 tetrons and extends into 3 additional 'internal' dimensions.(**)

-While the laws of gravity are due to the elastic properties of the substrate, particle physics interactions take place within the internal fibers, with the characteristic interaction energy being the Fermi scale.

-The masses of quarks and leptons can be determined from a Heisenberg type of Hamiltonian which describes the interactions of 2 neighboring tetrons.(***)

-3 of the quasiparticle excitations naturally have tiny masses, due to the conservation of total internal angular tetron momentum, and correspond to the 3 neutrino species.

-As a consequence of the free rotatability of the tetron isospins over each base point there is a local SU(2)xU(1) gauge symmetry.

-Electroweak spontaneous symmetry breaking takes place when neighboring tetron isospins align (freeze out) at energies/temperatures below the Fermi scale.

-Weak parity violation arises from the handedness of the internal tetrahedrons.

-Finally, Higgs fields and gauge bosons are excitations of bound tetron-antitetron pairs of neighboring fibers.

(*) Tetrons transform as the spinor representation 4 of SO(6) resp 8 of SO(6,1).
(**) Actually the tetrahedrons are formed by tetron isospin vectors and have a tetrahedral Shubnikov symmetry.
(***) The Hamiltonian can be written in terms of the tetron isospin vectors, see the enclosed review talk.

Details of the model like symmetry breaking, distribution of charges and mass generation are to be found in the following publications:

Space and Family, my first paper on the subject, contains the main idea and a geometrical interpretation, which is still relevant at this time e.g. for inclusion of gravity. Spacetime is considered discrete at very small distances, with only permutation symmetry transformations remaining relevant. When a fermion tetrahedron moves through a gravitational field, the directions of its 4 tetrons are given by the 4-bein which defines the gravitational field at that point.

World of Tetrons contains a first approach to the formation of vector bosons from tetrons

My 2021 Talk at the 16th Marcel Grossmann Meeting in Rome gives a good overview on the subject.

In 2022 I have returned to particle physics and tried to understand the origin of the Weinberg angle from tetron properties. Results are described, for example, in my Contribution to the 2023 Hamburg Conference of the European Physical Society and in reference 11 of that file, i.e. in B. Lampe, Fortsch. Phys. 72 (2024) 5, 2300258. In this connection I have written 2 recent articles, one with a ab initio calculation of the PMNS and CKM mixing of quarks and leptons and of the mixing between Z-boson and photon.

For the dedicated reader, I present my archives of how the tetron model has developed between 2007 and 2017, and in particular in the important years 2012, 2013 und 2014, and of how ich nahezu jeden Stein umgewendet habe, um den der Weisen zu finden:

Finally, I include some personal memories about the history of the microscopic model:
The ground laying idea actually started as early as 1987. When I visited Fermilab that summer, I was accompanied by my wife and our son half a year old. We stayed for a month and were given the opportunity to live in one of the traditional houses on the Fermilab property. We did it with ease to bring the fire brigade to the scene on one of the first days.

At that time there were the `preon models' - assuming quarks and leptons to be composed of smaller constituents - and the community had just agreed that such models cannot be built in a natural and consistent manner, most of all because of the extreme difference between the pointlikeness and necessarily high masses of the constituents and the relatively small masses of most quarks and leptons. I had followed the ansatz with curious interest, but not written any paper on the subject, feeling that this kind of approach was missing some essential ingredient.

Anyhow my main work was on QCD and my task at Fermilab was to discuss properties of hadron jets with someone from the lab staff. We had some interesting conversations, but when it came to filling a permanent scientific position the other year, I got away empty handed, as in all other institutions where I ever introduced myself.

The colleague had time only in the afternoons, so in the mornings I felt free to try to invent some ideas about the underlying nature of the quark lepton multiplet structure. There are so many reliable experimental results in that area that I thought quark and lepton properties to be a good starting point in order to develop a really fundamental theory. I further thought that if anything is of importance at all in this world of shadows, it is not logics or biology, not money or the rules of societies, but the deep structure of the physical universe.

I did not want to follow the mainstream SUSY, GUTs, Strings etc. These models emphasize symmetry (which is important, no question) but do not place enough value on a possible real material background, on which in my opinion any symmetry structure having to do with matter has to rely. I wanted to take this into account, when starting to develop a unified theory of my own. Since I had made elaborate studies in natural philosophy, I thought that I could do better.

In reality, my considerations did not start with such high demands. I set my sights lower and tried to get forward step by step. So actually, during my Fermilab stay I did not come up with final answers. I just made some observations which were to become important in later years. Namely, I noticed that the total of 24 quarks and leptons had some structural similarity to the ordering of the 24 group elements of the tetrahedral point group. Could be an accident, but I scanned many possibilities and did not find better answers.

Since as a young student I had some interest in theoretical chemistry, I began to restudy some textbooks on the tetrahedral point group with the idea in mind that tetrahedrons could supply a quark lepton substructure in a somehow more consistent manner than preon models do. It was only much later, in the new millenium, that I began to consider physical space to be made up of a discrete tetrahedral isospin arrangement and the observed `elementary particles' as excitations thereon.

The tetrahedral point group stayed in my head for a while, before I decided to publish, at least as a preprint, in 1998. Shortly afterwards I left scientific research because I did not find a permanent position. For a while I was frustrated and avoided all physics topics. It was only another 10 years later and after writing a novel of about 1000 pages, dealing with the side issues of life, that I returned to the problem, now as a private scholar and at first in a rather playful manner.

The first main problem I encountered was that the representation spaces of the tetrahedral group do not match the quark lepton multiplet structure exactly. In 2012 I realized that one of the tetrahedral black-and-white point groups when taken over from spin to isospin space does a better job. Accordingly, I introduced a tetrahedron of isospin vectors, and considered their interaction as a sort of `isomagnetism'. Quarks and leptons were then interpreted as vibrations of the isospin vectors. I noticed quite soon that there naturally arise 3 massless modes (interpreted as neutrinos) whose masselessness can be attributed to the conservation of isospin. I furthermore realized that (in contrast to an ordinary tetrahedron) a tetrahedron of pseudovectors is chiral, and that this can be used to explain the parity violation of the weak interacation.

In 2013 I united physical and isospin space to a larger 6-dimensional space, with a corresponding 6+1 dimensional spacetime continuum and began to understand the SM Higgs mechanism as an alignment of isospin vectors in that space. This requires that each point of 3-dimensional physical space actually is a tetrahedron, not extending into physical space but into the 3 extra dimensions. In other words, our universe is an invisible elastic substrate, microscopically formed by aligned isospin tetrahedrons. The tetrahedrons consists of tetrons transforming and making up the backbone of our universe. Furthermore, the transformations in isospin space are not just abstract symmetry operations but corresonds to real rotations in 3 extra dimensions. and the SM SSB is obtained as an `isomagnetic' symmetry breaking where isospin vectors form tetrahedrons which are aligned thus breaking the original isospin SU(2) symmetry.

I solved in passing another problem I always have had with particle physics philosophy. How does electron on one side of the universe know that it should behave the same way as an electron on the other side? How can all the information about the SM SSB buried in objects as light as neutrinos?

Also the vast difference beween the Planck and the Fermi scale (known as the hierarchy problem) becomes understandable within the tetron theory.
