一维量子多体系统的高效模拟

Efficient simulation of one-dimensional quantum many-body systems

G. Vidal

摘要:

我们提出了一种数值方法来模拟量子自旋链和系统的时间演化,根据局部相互作用的哈密顿量。该方案的效率取决于模拟进化中涉及的纠缠量。数值分析表明,这种方法可以用来,例如,有效地计算足够规则,但在其他任意一维量子多体系统的低能量动力学的时间依赖性。

英文摘要:

We present a numerical method to simulate the time evolution, according to a Hamiltonian made of local interactions, of quantum spin chains and systems alike. The efficiency of the scheme depends on the amount of the entanglement involved in the simulated evolution. Numerical analysis indicate that this method can be used, for instance, to efficiently compute time-dependent properties of low-energy dynamics of sufficiently regular but otherwise arbitrary one-dimensional quantum many-body systems.
