101Doublet-triplet splitting problem — In particle physics, the doublet triplet (splitting) problem is a problem of some Grand Unified Theories, such as SU(5), SO(10), E 6. Grand unified theories predict Higgs bosons (doublets of SU(2)) arise from representations of the unified group… …
102Stochastic electrodynamics — In theoretical physics, Stochastic electrodynamics (SED) refers to a theory which posits that the interaction of elementary particles with the vacuum radiation field, or zero point field, is ultimately responsible for various familiar quantum… …

104Order operator — In quantum field theory, an order operator or an order field is a quantum field version of Landau s order parameter whose expectation value characterizes phase transitions. There exists a dual version of it, the disorder operator or disorder… …
105Quantum inequalities — IntroductionQuantum inequalities are local constraints on the magnitude and extent of distributions of negative energy density in space time. Initially conceived to clear up a long standing problem in quantum field theory (namely, the potential… …
106Spectral asymmetry — In mathematics and physics, the spectral asymmetry is the asymmetry in the distribution of the spectrum of eigenvalues of an operator. In mathematics, the spectral asymmetry arises in the study of elliptic operators on compact manifolds, and is… …
107Volume operator — A quantum field theory of General Relativity provides operators that measure the geometry of space time. The volume operator V(R) of a region R is defined as the operator that yields the expectation value of a volume measurement of the region R,… …
108Subjective logic — is a type of probabilistic logic that explicitly takes uncertainty and belief ownership into account. In general, subjective logic is suitable for modeling and analysing situations involving uncertainty and incomplete knowledgeA. Jøsang.… …
109Mu problem — In theoretical physics, the μ problem is a problem of supersymmetric theories, concerned with understanding the parameters of the theory. The supersymmetric Higgs mass parameter μ appears as the following term in the superpotential: μHuHd. It is… …
