spinsystem
A spin system is a collection of quantum spins, often localized on lattice sites or embedded in engineered structures, used to model magnetic properties of materials or to realize quantum devices. The term spin system is often written as spin system or, in some contexts, as spinsystem. Each spin represents a quantum angular momentum degree of freedom, characterized by a spin quantum number S, with possibilities ranging from spin-1/2 to higher values. In solids, spins typically arise from electrons in atomic orbitals or from nuclear spins, and they interact via various couplings.
The behavior of a spin system is governed by its Hamiltonian, which includes exchange interactions between
Spin systems are studied across condensed matter physics and quantum information science. They are probed with
Dynamics of spins involve relaxation and decoherence as spins exchange energy with their environment. Spin diffusion
