WebWe observe chiral domains in the paraelectric nematic phase of a chemically achiral ferronematic. This behaviour is due to spontaneous symmetry breaking arising from saddle splay elasticity and helical segregation, the first example of this In particle physics, chiral symmetry breaking is the spontaneous symmetry breaking of a chiral symmetry – usually by a gauge theory such as quantum chromodynamics, the quantum field theory of the strong interaction. Yoichiro Nambu was awarded the 2008 Nobel prize in physics for describing this phenomenon ("for … See more Quantum chromodynamics Experimentally, it is observed that the masses of the octet of pseudoscalar mesons (such as the pion) are much lighter than the next heavier states such as the octet of See more • Conformal anomaly • Little Higgs See more
