Authors: Kiefer, Philip; Hakelberg, Frederick; Wittemer, Matthias; Bermudez, Alejandro; Porras, Diego; Warring, Ulrich; Schaetz, Tobias Contribution: Article Journal: PHYSICAL REVIEW LETTERS Publication date: 2019/11/21 DOI: 10.1103/PhysRevLett.123.213605 Abstract: We demonstrate Floquet engineering in a basic yet scalable 2D architecture of individually trapped and controlled ions. Local parametric modulations of detuned trapping potentials steer the strength of long-range [...]

Cold atoms in twisted-bilayer optical potentials

2020-01-16T12:54:15+01:00Tags: , , |

Authors: Gonzalez-Tudela, A.; Cirac, J., I Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2019/11/06 DOI: 10.1103/PhysRevA.100.053604 Abstract: The possibility of creating crystal bilayers twisted with respect to each other has led to the discovery of a wide range of novel electron correlated phenomena the full understanding of which is still under debate. Here we propose [...]
