Degree of coherence for electromagnetic fields
Optics Express, 2003 The relationship between the visibility of fringes and the degree of spatial coherence in electromagnetic two-pinhole interference is assessed. It is demonstrated that the customary definition of the degree of coherence of an electromagnetic field is flawed and a new quantity, free of the formal drawbacks, is introduced.

Coherence, purity and correlation for superconducting charge qubits
Results in Physics, 2023 In a model consisting of two superconducting charge qubits (SC-Qs), we study how the Josephson energy (JE) and temperature have an influence on the coherence, the degree of mixedness, and the nonclassical correlation.

Random pulse source with the temporal multi-complex degree of coherence
Results in Physics, 2023 Based on the coherence theory, the non-stationary optical fields with the complex degree of coherence (CDOC) are expanded from stationary fields, and random pulse sources with temporal multi-complex degree of coherence (TMCDOC) is introduced. Theoretical

A method for estimating coherence of molecular mechanisms in major human disease and traits
BMC Bioinformatics, 2020 Background Phenotypes such as height and intelligence, are thought to be a product of the collective effects of multiple phenotype-associated genes and interactions among their protein products.
