摘要:

我们使用三个囚禁原子离子自旋的集合对具有横向场的伊辛模型进行了量子模拟。通过对哈密顿量的精细操作,我们直接探测了各种场的基态和伊辛耦合的形式,从而得到了这个微观系统中磁序的相图。该技术可扩展到更大数量的捕获离子自旋,其中接近热力学极限的相变可以在理论变得难以处理的情况下进行研究。

英文摘要:

We perform a quantum simulation of the Ising model with a transverse field using a collection of three trapped atomic ion spins. By adiabatically manipulating the Hamiltonian, we directly probe the ground state for a wide range of fields and form of the Ising couplings, leading to a phase diagram of magnetic order in this microscopic system. The technique is scalable to much larger numbers of trapped ion spins, where phase transitions approaching the thermodynamic limit can be studied in cases where theory becomes intractable.
