5 days ago · Spin (physics) Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [1] [2] : 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory .
May 23, 2024 · Group structure. The rotation group is a group under function composition (or equivalently the product of linear transformations ). It is a subgroup of the general linear group consisting of all invertible linear transformations of the real 3-space . [2] Furthermore, the rotation group is nonabelian.
May 25, 2024 · These spin representations are also characterized as the finite-dimensional projective representations of the special orthogonal group that do not factor through linear representations. Equivalently, a spinor is an element of a finite-dimensional group representation of the spin group on which the center acts non-trivially. Overview
May 16, 2024 · Here, we provide a confined magnetic rectangular element to modulate the standing spin waves, by changing the saturation magnetisation ( MS ), exchange constant ( A ), and the aspect ratio of rectangular magnetic elements via micromagnetic simulation. It is found that the bulk mode and the edge mode of the magnetic element form a hybrid with ...
May 24, 2024 · For maximum spin, one must brush the ball well in a very fast motion. Without adequate speed, the spin is not very high. Similarly, with a lot of speed but a poor brushing motion, the spin is also a little lacking. Once you become more familiar with spin, you can also use the ball’s movement to help you analyze the spin on the ball. As ...
2 days ago · In this study we investigate the dynamics of tunable spin-orbit-coupled spin-1 Bose-Einstein condensates confined within a harmonic trap, focusing on rapid transport, spin manipulation, and splitting dynamics. Using shortcuts to adiabaticity, we design time-dependent trap trajectories and spin-orbit-coupling strength to facilitate fast transport with simultaneous spin flip. Additionally, we ...
