Observation of Floquet topological phases with large Chern numbers
Kai Yang, Shaoyi Xu, Longwen Zhou +7
One of the most intriguing advantage of Floquet engineering is to generate new phases with large topological invariants. In this work, we experimentally simulate a periodically que…
Structural analysis of nuclear spin clusters via two-dimensional nanoscale nuclear magnetic resonance spectroscopy
Zhiping Yang, Xi Kong, Zhijie Li +9
Two-dimensional Nuclear Magnetic Resonance (NMR) is essential in molecular structure determination. The Nitrogen-Vacancy (NV) center in diamond has been proposed and developed as a…
Floquet dynamical quantum phase transitions
Kai Yang, Longwen Zhou, Wenchao Ma +8
Dynamical quantum phase transitions (DQPTs) are manifested by time-domain nonanalytic behaviors of many-body systems.Introducing a quench is so far understood as a typical scenario…
Magnetic Resonance Imaging of Single Atoms
Philip Willke, Kai Yang, Yujeong Bae +2
Magnetic resonance imaging (MRI) revolutionized diagnostic medicine and biomedical research by allowing a noninvasive access to spin ensembles. To enhance MRI resolution to the nan…
Enhanced quantum coherence in exchange coupled spins via singlet-triplet transitions
Yujeong Bae, Kai Yang, Philip Willke +3
Manipulation of spin states at the single-atom scale underlies spin-based quantum information processing and spintronic devices. Such applications require protection of the spin st…
