Quantum number, any of several quantities of integral or half-integral value that identify the state of a physical system such as an atom, a nucleus, or a subatomic particle. Quantum numbers refer generally to properties that are discrete (quantized) and
gives the spin quantum numbers of some popular NMR nuclei. The projection of the angular momentum vector I onto an arbitrary axis (labelled z) is also quantized: [3]Iz=mħ where the magnetic quantum number, m, can have values between +I and −I in integral steps: [4]m=+I,+I−...
The symmetry has been observed in certain nuclei, particularly those with a large number of nucleons. Its applicability is limited to specific regions of the nuclear chart and certain energy regimes. Its study has contributed to the understanding of nuclear structure and dynamics in nuclear physics...
Spins of electrons in silicon MOS quantum dots combine exquisite quantum properties and scalable fabrication. In the age of quantum technology, however, the metrics that crowned Si/SiO2as the microelectronics standard need to be reassessed with respect to their impact upon qubit performance. We chart...
I recall with gratitude the series of highly inspiring discussions with Professor Joe Paldus that culminated in an attempt to chart the framework of a generalization of this connection to systems that consist of elementary particles with higher elementary spins [2]. This generalization was motivated,...

Over the preceding decade, levitational optomechanics has emerged as a versatile platform for addressing crucial questions in the physical sciences, ranging from the macroscopic limits of quantum mechanics1 to the thermodynamic limits of computation2. It makes use of optical forces, which are generated...
FIG. 1C is a flow chart showing an example process195for increasing polarization of a spin ensemble. The example process195can be performed, for example, in the example magnetic resonance system100shown in FIG. 1A or in another type of system. The example process195shown in FIG. 1C can ...
