The definition of a spin quantum number is a measure of the intrinsic angular momentum that an elementary particle has. This number is denoted as ms where m stands for momentum and s stands for spin, and spin is the fourth quantum number that describes a particle. The spin of a particle ...
We consider here the problem of a "giant spin", with spin quantum number S鈮 1, interacting with a set of microscopic spins. Interactions between the microscopic spins are ignored. This model describes the low-energy properties of magnetic grains or magnetic macromolecules (ferromagnetically or ...

In the impurity potential, S is the spin quantum number, \(\left( {S_\mu ^x,S_\mu ^y,S_\mu ^z} \right)\) is the direction of the localized magnetic moment, and μ indexes the different scattering channels, including different orbitals in a single impurity and multiple sites in ...
In particular, we show that the phase-string sign structure is associated with the quantum fluctuation or the transverse part of S2 = 3/4 in the one-hole case with Sz = ±1/2. It is such quantum fluctuation, in addition to the longitudinal Sz = ±1/2 component, that ...
In theory, whether or not the coupling constant Kij describes the exchange effects or also the (effective) magnetic spin–spin coupling depends on the calculation of the approximate wave function, i.e., it depends on the Hamiltonian chosen for the calculation of the wave function. In experiment...

The first set is obtained at a special value of the anisotropy ( q = \exp(i2\pi (N-1)/N) q = \exp(i2\pi (N-1)/N) ) and describes in particular the ground state and nearby excitations as a sum of free-fermion quasienergies. The second set of solutions provides the energies ...
The model describes low-energy fermions interacting with their own collective spin fluctuations, which soften at the antiferromagnetic transition. We argue that in 2D, the system has two typical energies—an effective spin-fermion interaction g and an energy ωsf below which the system behaves as ...
Quantum spin liquids (QSLs) have been at the forefront of correlated electron research ever since their proposal in 1973, and the realization that they belong to the broader class of intrinsic topological orders. According to received wisdom, QSLs can ar
