囚禁离子系统中的竞争多体相互作用

Competing many-body interactions in systems of trapped ions

A. Bermudez, D. Porras, M. A. Martin-Delgado

摘要:

提出并理论分析了激光诱导囚禁离子间3-自旋相互作用的实验方案,通过适当选择激光的强度和频率,3-自旋耦合可以占主导地位或与2-自旋项和磁场相当.通过这种方式,捕获的离子可以用来研究自然界中没有对应物的奇异量子相。我们研究了有效三自旋哈密顿量的有效性条件,并定性地预测了系统的量子相图。

英文摘要:

We propose and theoretically analyse an experimental configuration in which lasers induce 3-spin interactions between trapped ions.By properly choosing the intensities and frequencies of the lasers, 3-spin couplings may be dominant or comparable to 2-spin terms and magnetic fields. In this way, trapped ions can be used to study exotic quantum phases which do not have a counterpart in nature. We study the conditions for the validity of the effective 3-spin Hamiltonian, and predict qualitatively the quantum phase diagram of the system.
