WebApr 11, 2024 · We theoretically investigate, within Schwinger-boson mean-field theory, the transition from a gapped Z 2 quantum spin liquid, in a J 1 − J 2 Heisenberg spin-1 2 system in a honeycomb lattice, to a chiral Z 2 spin-liquid phase under the presence of time-reversal symmetry-breaking scalar chiral interaction (with amplitude J χ).We numerically obtain a … WebFeb 14, 2024 · Inside the guide field, a direct current spin rotator (DC1, not depicted) is placed in front of the interferometer and produces a local effective magnetic field in x-direction.
Oil Blobs Spin in a Pore Full of Ferrofluid in a Rotating Magnetic Field
Spin is a conserved quantity carried by elementary particles, and thus by composite particles (hadrons) and atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum. The orbital angular momentum operator is the quantum-mechanical … See more As the name suggests, spin was originally conceived as the rotation of a particle around some axis. While the question of whether elementary particles actually rotate is ambiguous (as they appear point-like), … See more Particles with spin can possess a magnetic dipole moment, just like a rotating electrically charged body in classical electrodynamics. … See more Spin projection quantum number and multiplicity In classical mechanics, the angular momentum of a … See more In tables of the spin quantum number s for nuclei or particles, the spin is often followed by a "+" or "−". This refers to the parity with … See more In ordinary materials, the magnetic dipole moments of individual atoms produce magnetic fields that cancel one another, because each dipole points in a random direction, with the overall average being very near zero. Ferromagnetic materials below their See more Operator Spin obeys commutation relations analogous to those of the orbital angular momentum: $${\displaystyle \left[{\hat {S}}_{j},{\hat {S}}_{k}\right]=i\hbar \varepsilon _{jkl}{\hat {S}}_{l},}$$ See more Spin has important theoretical implications and practical applications. Well-established direct applications of spin include: • Nuclear magnetic resonance (NMR) spectroscopy in chemistry; • Electron spin resonance (ESR … See more WebMany technologically useful magnetic oxides are ferrimagnetic insulators, which consist of chemically distinct cations. Here, we examine the spin dynamics of different magnetic cations in ferrimagnetic NiZnAl-ferrite (Ni 0.65 Zn 0.35 Al 0.8 Fe 1.2 O 4) under continuous microwave excitation.Specifically, we employ time-resolved x-ray ferromagnetic … children\u0027s hospital north campus
