In atomic physics, spin–orbit coupling, also known as spin-pairing, describes a weak magnetic interaction, or coupling, of the particle spin and the orbital motion of this particle, e.g. the electron spin and its motion around an atomic nucleus. One of its effects is to separate the energy of internal states of the atom, e.g. spin-aligned and ...
In physics, the C parity or charge parity is a multiplicative quantum number of some particles that describes their behavior under the symmetry operation of charge conjugation. Charge conjugation changes the sign of all quantum charges (that is, additive quantum numbers ), including the electrical charge , baryon number and lepton number , and ...
The renormalization group was initially devised in particle physics, but nowadays its applications extend to solid-state physics, fluid mechanics, physical cosmology, and even nanotechnology. An early article [ 2 ] by Ernst Stueckelberg and André Petermann in 1953 anticipates the idea in quantum field theory .
In the 16 June 2017, issue of Science, Yin et al. report setting a new quantum entanglement distance record of 1,203 km, demonstrating the survival of a two-photon pair and a violation of a Bell inequality, reaching a CHSH valuation of 2.37 ± 0.09, under strict Einstein locality conditions, from the Micius satellite to bases in Lijian, Yunnan ...
Ligand-Field scheme summarizing σ-bonding in the octahedral complex [Ti(H 2 O) 6] 3+. In molecular symmetry terms, the six lone-pair orbitals from the ligands (one from each ligand) form six symmetry-adapted linear combinations (SALCs) of orbitals, also sometimes called ligand group orbitals (LGOs).
Iranian activist Kianoosh Sanjari, who died by suicide this week in protest at political imprisonments by the regime, was buried Friday in the capital Tehran. Sanjari took his own life Wednesday ...
Rory McIlroy's charge at the Abu Dhabi Championship faltered when he found water off his drive and made double bogey on the last hole on Saturday, leaving him five shots off the lead held by Paul ...
The J/ψ (J/psi) meson / ˈ dʒ eɪ ˈ s aɪ ˈ m iː z ɒ n / is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark.Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as "charmonium" or psions. [1]
