Exact dynamics of XX central spin models
arXiv:0904.0695 · doi:10.1088/0031-8949/2009/T135/014049
Abstract
The dynamical behavior of a star network of spins, wherein each of N decoupled spins interact with a central spin through non uniform Heisenberg XX interaction is exactly studied. The time-dependent Schrodinger equation of the spin system model is solved starting from an arbitrary initial state. The resulting solution is analyzed and briefly discussed.
