First-order exchange approximation
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1963It is shown that when the Born approximation is applied to rearrangement collisions in the customary way, terms of the first order in the interaction energy between the colliding particles are omitted from the exchange scattering amplitude.

The Heisenberg ferromagnet with higher-order exchange [PDF]
The authors investigate the properties of ferromagnetic spin systems with higher-order exchange interactions, in particular with four-spin terms of the form (Si.Sj)(Sk.Sl) and (Si.Sj)(Sj.Sk). Using the Green function equation of motion method, and simple decoupling approximations, they obtain renormalised spin-wave energies, magnetisation curves, and ...

Order Exchange Key in Data Encryption
2012This Paper presents a new data encryption conception and algorithm. Generally the method of encryption is fixed and different key gets different encryption result. In this paper, one general data encryption key DK is used, and from the DK key we can get another key MK which is used to change the encryption method.
