0000048655 00000 n manuscripts have not been received by the Editorial Office yet. The behavior of electrons in solids is intimately related to symmetry and dimensionality, and it is the interaction of these two that dictates the topological properties of materials. 0000051475 00000 n The below list represents only planned manuscripts. Such a dynamical rearrangement of symmetry describes, in well definite formal terms, metamorphosis processes. 0000013018 00000 n Our conclusions apply to elementary particle physics, condensed matter physics and to the physics of the living phase of the matter (biology and neuroscience) and can be as well applied to some aspects of linguistics in the generation of meanings, in the transition from syntax to semantics. As Yang has stated: Symmetry dictates interaction. For example, spin flip operations with the quaternions, (This article belongs to the Special Issue, Nonlinearity in Quantum Mechanics may have extrinsic or intrinsic origins and is a liable route to a chaotic behaviour that can be of difficult observations. ;q�K�V��e���e6~Vf�?�$6��Â�N��w�ޞe6[M�C9�!��l��C�-�wh������A��D9ow�=�펷����$�@ Typically, the amplitude of this (electric or magnetic) moment is called the transition moment. When it was first published in the 1950s, most people did not expect it to survive. The metamorphosis phenomenon is generated by the loss of infrared contributions in physical states and observables due to their localized nature. 0000010930 00000 n 0000019064 00000 n They act on the Hilbert space. All manuscripts are thoroughly refereed through a single-blind peer-review process. So, I'll give one trivial example and then I'll make it more elaborate… Help us to further improve by taking part in this short 5 minute survey, Special Issues and Collections in MDPI journals, A Knot Theoretic Extension of the Bloch Sphere Representation for Qubits in Hilbert Space and Its Application to Contextuality and Many-Worlds Theories, The Emergence of Chaos in Quantum Mechanics, The role of symmetry in physics: historical and philosophical aspects, CPT symmetry in particles physics and cosmology, PT symmetry, dissipative systems, and quantum computing, Dynamical symmetries and chaotic behavior in physical systems, Irreversibility and time-symmetry breaking. In the end, it is correct to say “That symmetry dictates interactions, that geometry is at the heart of physics” (Chen Non Yang, Einstein's impact on theoretical physics, Contemporary Physics, 1980). In Quantum Mechanics, the Symmetry is implemented by a Unitary Transformation U ^ acting on states and observables. 0000018865 00000 n The. “Symmetry Dictates Interaction” ——For the Jubilee of the Non-abelian Gauge Fields LI Hua-Zhong (Advanced Research Center and Physics Department, Zhongshan University, Guangzhou 510275, China) We will discuss two famous conjectures about symmetry in quantum gravity. However, by the 1970s, after the first round of experimental evidences, and after some imp… 0000001776 00000 n The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs).

Precision measurements and symmetry tests that aim to challenge the Standard Model (SM) of electroweak interactions and probe/discover its possible extensions (BSM) Qweak muon g-2. However, electromagnetism is an Abelian gauge theory. ... symmetry dictates interaction; PDF download. Some of these Yang summarized the gauge invariance approach to the study of fundamental interactions with the expression 'symmetry dictates interaction' ; this goes well with the principle above that one should include the cross term because it obeys symmetry. 0000125444 00000 n A crucial role in the metamorphosis processes is played by the coherence of the correlations generating order and self-similar fractal patterns. 0000003342 00000 n The closest suggestion comes from condensed matter and the numerous points of contact with QFTs. 0000003071 00000 n of symmetry is the existence of conservation laws. Δ o Δ o Δ o e g (σ*) e g (σ*) e g (σ*) t (π) t 2g (n.b.) The dissipative dynamics and evolution, the arising of the arrow of time and entanglement are also discussed. Manuscripts can be submitted until the deadline. Dr. Roberto PassanteGuest Editors. 0000007036 00000 n 0000126095 00000 n The coherence of the correlations generating order and self-similar fractal patterns plays a crucial role. 0000125600 00000 n How did this concept evolve in physics? It is a sign of the high level of coherence of our theories on the nature that even the GR, in spite of physical differences, were later revealed to belong to the same "mathematical key bunch" of gauge theories. Even today, one can still admire this synthesis, which foreshadows the powerful notion of symmetry breaking, at the base of unification programs in cosmology and particle physics. The first example of this was general relativity where Einstein employed the symmetry of space-time under local changes of coordinate to determine the laws of gravity. We use cookies on our website to ensure you get the best experience. One can claim that “Symmetry dictates Interaction”, as stated by Yang. Deadline for manuscript submissions: 30 November 2020.

Our dedicated information section provides allows you to learn more about MDPI. 0000006715 00000 n In other words, certain elements of symmetry can coexist with certain phenomena, but they are not necessary. Among the many important contributions you made, people consider Yang–Mills theory to be the most important. 1. submitted to MDPI journals are subject to peer-review. 0000159110 00000 n Modern theories of fundamental interactions are based on the concept of "connections," a generalization of the vector potential A. So it's not a symmetry of anything. Research articles, review articles as well as short communications are invited. 0000049203 00000 n For example, spin flip operations with the quaternions, Subscribe to receive issue release notifications and newsletters from MDPI journals, You can make submissions to other journals. 0000020034 00000 n 0000018323 00000 n 0000002284 00000 n Symmetry often plays a fundamental role in modern quantum physics.
