Physical Realization of the Parity Anomaly in Condensed Matter Physics
Physical Review Letters, 1986We show that a PbTe-type narrow-gap semiconductor with an antiphase boundary (or domain wall) has currents of abnormal parity and induced fractional charges. A model is introduced which reduces the problem to the physics of a Dirac equation with a soliton in background electric and magnetic fields.

Parity and chivalry in nuclear physics
Nature, 1997Forty years ago, the world of physics was stunned by the discovery that nuclear beta-decay does not respect symmetry between left and right. But the credit for this conclusion has not been properly attributed.

Parity of esteem between mental and physical health
BMJ, 2014Means different things to different people, making it difficult to enforce Although parity of esteem between mental and physical health has been a high profile political issue in the UK since 2011, debates about the relative esteem and provision for mental and physical health are long standing.

Atomic parity violation as a probe of new physics
Physical Review Letters, 1990Effects of physics beyond the standard model on electroweak observables ares studied using the Peskin-Takeuchi isospin-conserving, S, and -breaking, T, parametrization of ``new'' quantum loop corrections. Experimental constraints on S and T are presented. Atomic parity-violating experiments are shown to be particularly sensitive to S with existing data

Parity nonconservation in nuclear physics
Physics of Atomic Nuclei, 2002We present an overview of the parity-nonconservation effects in nuclear physics. In the processes of polarized neutron scattering by nuclei, apart from the ordinary dynamical enhancement, we also consider the additional resonant enhancement in the entrance channel due to the proximity of the compound-nucleus p-wave resonance.

Digital-Physical Parity for Food Fraud Detection
2019Food fraud has an adverse impact on all stakeholders in the food production and distribution process. Lack of transparency in food supply chains is a strong factor contributing to food fraud. With limited transparency, the insights on food supply chains are fragmented, and every participant has to rely on trusted third parties to assess food quality ...

Parity–Time Symmetry Synthetic Lasers: Physics and Devices
Advanced Optical Materials, 2019AbstractThe invention of the laser has revolutionized modern science and engineering as well as our daily lives. Recently, a new class of lasers based on concepts borrowed from parity–time symmetry in quantum mechanics has emerged. Parity–time symmetry, initially applied to condensed matter systems, extends canonical quantum theory to non‐Hermitian ...

Parity Violation in Atomic Physics
1991Physicists have been convinced for a long time that the laws of nature do not distinguish between left and right, and therefore parity (mirror symmetry) is conserved in all interactions. The discovery in 1956 that parity is not conserved for the weak interaction governing β-decay had an immediate and profound influence on nuclear and elementary ...
