量子模拟器中磁相变的量子催化
Quantum Catalysis of Magnetic Phase Transitions in a Quantum Simulator
摘要：
我们控制量子涨落，以创建一个可调的纵向磁场使用6至10个原子离子自旋系统的经典伊辛模型的基态磁相位。由于长程伊辛相互作用，各种基态自旋组态被多个一级相变分开，这在我们的零温度系统中不能由热涨落驱动。相反，我们使用横向磁场作为量子催化剂来观察完整的分形魔鬼楼梯的第一步，它出现在热力学极限，可以映射到大量的多体和能量优化问题。
英文摘要：
We control quantum fluctuations to create the ground state magnetic phases of a classical Ising model with a tunable longitudinal magnetic field using a system of 6 to 10 atomic ion spins. Due to the long-range Ising interactions, the various ground state spin configurations are separated by multiple first-order phase transitions, which in our zero temperature system cannot be driven by thermal fluctuations. We instead use a transverse magnetic field as a quantum catalyst to observe the first steps of the complete fractal devil's staircase, which emerges in the thermodynamic limit and can be mapped to a large number of many-body and energy-optimization problems.
