Scarcely any term connects art and science more closely than symmetry. This was already a theme in ancient times, as is found in Vitruvius, for example. On the beach of an unknown island, a shipwrecked traveler finds neatly arranged geometric figures. Can he conclude from this that there is an intelligent creator (perhaps even a god)?

Abstract The postwar Red Scare and McCarthyism solidified Anderson’s left-of-center politics. He solidified his position at Bell Labs by using the concept of superexchange to explain neutron scattering data from transition metal oxides.

Physical Review Letters, 1985
The spontaneous symmetry breaking in higher-dimensional unified field theories is discussed in a general setting. A purely geometric symmetry-breaking mechanism involving no free parameters is presented, in which the symmetry is broken by the higher-dimensional metric through Einstein's equation.

Symmetry Breaking Breaks Friction
Acta Physica Hungarica A) Heavy Ion Physics, 2004The harmonic analysis of the symmetry breaking is used to study the interaction and inter-layer motion of double-wall carbon nanotubes shells. The tremendous total symmetry reduction with respect to the high symmetry of the isolated layers results in low interaction: its decreasing with the symmetry breaking rate explains the observed small friction.

Symmetry and symmetry breaking
2023This entry begins with a brief description of the historical roots and emergence of the concept of symmetry that is at work in modern science. It then turns to the application of this concept to physics, distinguishing between two different uses of symmetry: symmetry principles versus symmetry arguments.

Symmetries and symmetry breaking
2017Abstract The spontaneous breaking of symmetries (SSB) is discussed for global symmetries and Goldstones theorem is derived. The renormalisation of theories with SSB is studied using the effective potential. Then SSB is applied to the Abelian Higgs model, both on the classical and quantum level.

AbstractFor the quartic tensor models, the critical point at which the continuum limit is reached corresponds to a phase transition accompanied by a symmetry breaking. This chapter analyzes a simplified quartic tensor model for which the vacuum state in the broken phase can be identified.
