摘要
We have made a computer investigation of coherent effects in polarized systems of nuclear or electron spins using a microscopic approach. The many-body problem is reduced to simulation of dynamics of spins that interact with each other and with external fields. We show that a spin system in a resonance circuit can emit a coherent superradiative pulse when the system is initially in an essentially unstable state. For a polarized spin system without circuit, we have found a new regime of coherent emission in the case of an external resonance pumping.
