Chiral symmetry condensed matter
WebChiral symmetry is a symmetry of QCD in the limit that the quark masses are set equal to zero. However, this symmetry is not manifest in the spectrum of hadron masses, even after we correct for the fact that the masses of quarks are not exactly zero. Instead, this symmetry is realized in a different way; it is said to be spontaneously broken. WebSurface superconductivity has recently been observed on the (001) surface of the topological crystalline insulator Pb1-xSnxTe using point-contact spectroscopy
