Abstract: A brief review of alternative phenomenological approaches to the spin dynamics of antiferromagnets are discussed in virtue of modern interest to ultrafast spin dynamics and it application. Specific properties of antiferromagnets, first of all, the… read more here.

Abstract: We develop a nonperturbative theory for hole dynamics in antiferromagnetic spin lattices, as described by the t-J model. This is achieved by generalizing the self-consistent Born approximation to nonequilibrium systems, making it possible to calculate… read more here.
