晶格中结晶偶极玻色子的序参量与探测

Order parameter and detection for crystallized dipolar bosons in lattices

Budhaditya Chatterjee, Axel U. J. Lode

摘要:

研究了一维光晶格中具有偶极-偶极相互作用玻色子的基态性质。值得注意的是,结晶过程发生强偶极相互作用。在这里,我们提供了一个详细的表征和方法来测量所得的晶相。使用减少的单体密度矩阵的本征值,我们定义了一个序参量,产生的密度和两体密度的分析相一致的图。我们证明,相图可以检测实验使用单次测量的方差。

英文摘要:

We explore the ground-state properties of bosons with dipole-dipole interactions in a one-dimensional optical lattice. Remarkably, a crystallization process happens for strong dipolar interactions. Herein, we provide a detailed characterization and a way to measure the resulting crystal phase. Using the eigenvalues of the reduced one-body density matrix we define an order parameter that yields a phase diagram in agreement with an analysis of the density and two-body density. We demonstrate that the phase diagram can be detected experimentally using the variance of single-shot measurements.
