Penrose, Twistor algebra, J. A. Yelleshpur Srikant, Emergent unitarity from the amplituhedron, JHEP 01 (2020) 069 [arXiv:1906.10700] [INSPIRE]. Instead of describing scattering processes in terms of familiar variables like position and time and depicting them in thousands of Feynman diagrams, the BCFW relations are best couched in terms of strange variables called twistors, and particle interactions can be captured in a handful of associated twistor diagrams. For example for pure Yang Mills there are all plus(or minus) helicity amplitude, at tree level they all vanish. We are independent media, totally supported by you. In the maximal sign-flip case they are finite one-loop octagons.

Penrose developed twistors also with a quantum gravity motivation: they provide a very different set of basic variables, with usual space-time points not the fundamental objects. Hodges is a wonderful story of someone who didnt follow fashion, but stuck to pursuing something truly worthwhile, its great that he has now been getting attention for this, as his work has become useful for more popular research programs. As usual, Arkani-Hamed was a clear and very engaging speaker. In the mid-2000s, more patterns emerged in the scattering amplitudes of particle interactions, repeatedly hinting at an underlying, coherent mathematical structure behind quantum field theory.

The amplituhedron A 6, 2 (2) is the image of the top-cell for the positive Grassmannian G + (2, 6), labelled by the decorated permutation {3,4,5,6,7,8}. At one time (about 1980) N=8 SUGRA was considered a candidate theory of everything until it was noticed that its gauge group is too small and it does not have chiral fermions or room for symmetry breaking. endobj For those who keep asking about interesting, promising ideas about fundamental physics to work on, twistors are something they definitely should look into. But even 2-gluon to 4-gluon processes were so complex, a group of physicists had written two years earlier, that they may not be evaluated in the foreseeable future., Stephen Parke and Tomasz Taylor, theorists at Fermi National Accelerator Laboratory in Illinois, took that statement as a challenge. The U.S. Department of Energy's Office of Scientific and Technical Information On its own the theory is very interesting but of limited use. This is exciting because people have always speculated that some of these things may be emergent in theories of quantum gravity. Article [1], Using twistor theory, BrittoCachazoFengWitten recursion (BCFW recursion) relations involved in the scattering process may be represented as a small number of twistor diagrams.

It was a geometric representation of real particle data, such as the likelihood that two colliding gluons will turn into four gluons. According to the principle of unitarity, the sum of the probabilities for every possible outcome is 1. Certainly texts that address the probabilities of different particle interactions will be incomplete without mentioning this overall connection to geometry. In keeping with this idea, the new geometric approach to particle interactions removes locality and unitarity from its starting assumptions. The basic idea was that the central objects of the theory were rays of light, twistors, rather than particles, and the various terms of the method could be interpreted as volumes of tetrahedrons in twistor space.

There was just one problem: they didn't know why. endobj The tree amplituhedron is a positive geometry encoding the tree-level scattering amplitudes 7 in the momentum super-twistor space 8 and we can think of it as the generalisation of projective polytopes into the Grassmannian space, in the same way as the positive Grassmannian is the generalisation of a projective simplex. endstream Is something's right to be free more important than the best interest for its own species according to deontology? This would presumably require superstring theory to have the same dual superconformal symmetry as super Yang Mills, or some other even more elaborate infinite dimensional symmetry.

In the 1980s, the US was constructing the Texas Superconducting Super Collider. Karp and L.K. Arkani-Hamed and Trnka discovered that the scattering amplitude equals the volume of a brand-new mathematical object the amplituhedron. Moderators are staffed during regular business hours (New York time) and can only accept comments written in English. Why is superdeterminism generally regarded as a joke? In fact, as detailed in a paper posted to arXiv.org in December by Arkani-Hamed, Bourjaily, Cachazo, Alexander Goncharov, Alexander Postnikov and Jaroslav Trnka, the twistor diagrams gave instructions for calculating the volume of pieces of this object, called the positive Grassmannian.

I think it is more accurate to say that with the amplituhedron space-time is derived rather than emergent. Nx\5 F] {. Equivalently, the amplituhedron can be fully described in binary: canonical projections of the geometry down to one dimension have a specified (and maximal) number of "sign flips" of the projected data. stream But something was still missing. [clarification needed] They are encoded in the positive geometry of the amplituhedron, via the singularity structure of the integrand for scattering amplitudes. Google Scholar. Phys. geometry significantly advances a decades-long effort to reformulate quantum field theory, the body of laws describing elementary particles and their interactions. N. Arkani-Hamed and J. Trnka, The Amplituhedron, JHEP 10 (2014) 030 [arXiv:1312.2007] [INSPIRE]. [1], The twistor approach is relatively abstract. Having space-time and unitarity as a derived concept may be a step towards emergence but it is not the same thing. Plato said it 2500 years ago (tongue in cheek), My main sources of info are the latest 130 minute talk at. You can easily do, on paper, computations that were infeasible even with a computer before..

[1] Arkani-Hamed suggests this is why amplituhedron theory simplifies scattering-amplitude calculations: in the Feynman-diagrams approach, locality is manifest, whereas in the amplituhedron approach, it is implicit. N. Arkani-Hamed, H. Thomas and J. Trnka, Unwinding the Amplituhedron in Binary, JHEP 01 (2018) 016 [arXiv:1704.05069] [INSPIRE]. This is a modest advance in mathematical physics, one that for some reason a few months ago garnered a lot of hype (see here for more about this). One can get into an argument about what of such currently fashionable ideas are the ones that are not worthwhile, but if you want an example, Ive made it very clear what I think of the multiverse. Emergence of space-time implies that space and time are approximate and there are places such as a black hole singularity where they cease to be a smooth manifold. This undermines the case for even a transient, unobservable existence for such virtual particles. T. Dennen, I. Prlina, M. Spradlin, S. Stanojevic and A. Volovich, Landau Singularities from the Amplituhedron, JHEP 06 (2017) 152 [arXiv:1612.02708] [INSPIRE].

On this Wikipedia the language links are at the top of the page across from the article title. I have advocated the idea that string theory has very large symmetries in the form of necklace algebras so these ideas seem on the right track to me. Schwarz and J. Scherk, Supersymmetric Yang-Mills Theories, Nucl. Yesterday Nima Arkani-Hamed was here at Columbia, giving a theory seminar on the topic of the Amplituhedron, which is a characterization of the integration region in a calculation of scattering amplitudes by integrating over regions in the so-called positive Grassmannian. It is possible that true emergence may be a feature in a wider generalisation of the theory especially if it can be applied to quantum gravity where emergence is expected to be a feature.

Recently, a strange duality has been found between string theory and quantum field theory, indicating that the former (which includes gravity) is mathematically equivalent to the latter (which does not) when the two theories describe the same event as if it is taking place in different numbers of dimensions. The seemingly irreconcilable conflict between gravity and quantum field theory enters crisis mode in black holes. A preprint version of the article is available at arXiv.
