Advanced published papers regarding valid unification theories?

[Potential]

Questions: Where can I obtain the most advanced published papers regarding valid unification theories? If there are none, which published papers will get me closest when combined in their respective categories?

Comment: It is obvious to me through speculation, physical laws have yet to become discovered which bind everything together in harmonic concert. In my view, these solutions can be discovered when the ability to drill down to the Planck Length occurs. My thinking is, there is another layer of information beyond this smallest conceived measurement that can provide proof of unification. I also have a hunch this minute layer not only separates a vein of high unified energy, but it is expected to be impossible for us to, particle jump, to the other side.

From Wikipedia, the free encyclopedia

In physics, the Planck length, denoted, is unit of length, equal to about 1.6 × 10-35 meters. It is a base unit in the system of Planck units, the most widely used system of natural units. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum (celeritas), Planck's constant, and the gravitational constant. Current theory suggests that 1 Planck length is the smallest distance or size about which anything can be known.

You might start here: http://pdg.lbl.gov/2008/reviews/rpp2008-rev-guts.pdf,
also here is a good reference: http://arxiv.org/abs/0807.4921.

The subject is a broad one, and there are also several books dedicated to it which are good.

It depends on how you see the problem of unification. From one perspective the central unification problem is to reconcile quantum theory with our theory of geometry (how geometry is affected by matter and why we ordinarily experience it as almost but not quite the same as the flat geometry of Pythagoras and Euclid.)

In other words, the central unification problem is a quantum theory of what space and time are and how they interact with matter.

At the present, our dominant theory of what space and time are, and how geometry interacts with matter, is 1915 classic General Relativity.

Quantum field theory (QFT) our basic theory of matter has not been put on a GR basis. One way of stating the unification goal I'm talking about is to reach a general relativistic quantum field theory. To construct a new model of spacetime, and to rebuild QFT on that new geometric foundation.

There are several quite different ways of seeing the main unification goal and it would be arrogant and not very bright to pretend that only one is the correct one, or that only one version of the goal subsumes all the others. In any case you can pick up on a variety of different currents just by keeping alert. I will describe one.

You ask about an up-to-date paper. Here is something rather surprising. I think that from one perspective one of the most advanced papers is written for general audience and was published in the Scientific American last year!

It is called The Self-Organizing Quantum Universe. It's extensively illustrated with graphics that help get the ideas across. Published July 2008. Shows what a new picture of spacetime might turn out to look like. Interesting fractal quality down at Planck length scale. Space no longer 3D at very small scale---dimensionality becomes fractional and declines down to numbers like 2.1 and 1.9, reminiscent of fractals.
Several other approaches to quantum geometry/gravity have also shown signs of this fractal or chaotic behavior of geometry at very small scale. One thinks of seething wormholes, foam, froth, something. Not the regular continuum. Perhaps a Heisenberg uncertain concept of continuum. Anyway a new model of the continuum is emerging from several of these QG approaches. The special thing about this SciAm article is that it reports on a mathematical model of quantum continuum which looks right at large scale.
At large scale it gives a classic solution to General Relativity, one with dark energy, and realistic accelerating expansion as we seem to be detecting today. The socalled De Sitter universe. This is good news, so I guess that is why that team made the Scientific American with their result.

If you want more technical articles, they have links at the end of the SciAm article, and also you can ask. They are easy to get.

TY BenTheMan!

TY Marcus!

Marcus...very interesting you mentioned fractal...

Interesting fractal quality down at Planck length scale.

...because, allot of information can be squeezed in a fractal similar to a hologram...

A geometric pattern that is repeated at ever smaller scales to produce irregular shapes and surfaces that cannot be represented by classical geometry. Fractals are used especially in computer modeling of irregular patterns and structures in nature.

French, from Latin frāctus, past participle of frangere, to break. See fraction.

In computer graphics it has been shown that the vast amount of information contained in a natural scene can be compressed very effectively by identifying the basic set of fractals therein together with their rules of construction. When the fractals are reconstructed, a close approximation of the original scene is reproduced.
