If one measures the spin along a vertical axis, electrons are described as "spin up" or "spin down", based on the magnetic moment pointing up or down, respectively. To mathematically describe the experiment with spin + particles, it is easiest to use Dirac's bra–ket notation. As the particles pass through the Stern–Gerlach device, they are ...
Schematic of the spin Hall effect Schematic of the inverse spin Hall effect. The spin Hall effect (SHE) is a transport phenomenon predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971. [1] [2] It consists of the appearance of spin accumulation on the lateral surfaces of an electric current-carrying sample, the signs ...
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
In particle physics, spin polarization is the degree to which the spin, i.e., the intrinsic angular momentum of elementary particles, is aligned with a given direction. [1] This property may pertain to the spin, hence to the magnetic moment, of conduction electrons in ferromagnetic metals, such as iron, giving rise to spin-polarized currents ...
Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. [1] [2] Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism for spin angular momentum.

According to the Tax Foundation, Trump’s proposed tax cut would reduce tax revenue by about $1.4 trillion from 2025 to 2034, measured on a conventional basis.
Alabama finished the season 9-3, missing out on the SEC title game after in-conference losses to Tennessee — who made the CFP as the No. 9 seed — and unranked opponents Oklahoma and Vanderbilt.
The magnetization is effectively spin-locked around an effective B 1 field created by the vector sum of the applied B 1 and any off-resonant component. The spin-locked magnetization will relax with a time constant T 1ρ , which is the time it takes for the magnetic resonance signal to reach 37% (1/e) of its initial value, M x y ( 0 ...
