説明
<jats:title>Fermionic Quantum Magnetism</jats:title> <jats:p> Optical lattices loaded with cold atoms have been used successfully as quantum simulators of condensed matter systems; however, in the case of fermionic quantum magnetism, achieving low enough temperatures has been a major obstacle. <jats:bold> Greif <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6138" page="1307" related-article-type="in-this-issue" vol="340" xlink:href="10.1126/science.1236362">1307</jats:related-article> , published online 23 May; see the Perspective by <jats:bold> <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6138" page="1297" related-article-type="in-this-issue" vol="340" xlink:href="10.1126/science.1239873">Porto</jats:related-article> </jats:bold> ) selectively tuned the exchange interactions in an optical lattice of fermions, forcing a redistribution of entropy such that in the low-entropy subsystem the effective temperature was sufficiently low enough to lead to magnetic correlations. </jats:p>
