Topological quantum synchronization of fractionalized spins

Kavli Affiliate: Joel E. Moore | First 5 Authors: Christopher W. Wächtler, Joel E. Moore, , , | Summary: The gapped symmetric phase of the Affleck-Kennedy-Lieb-Tasaki (AKLT) model exhibits fractionalized spins at the ends of an open chain. We show that breaking SU(2) symmetry and applying a global spin-lowering dissipator achieves synchronization of these fractionalized […]

Three-dimensional imaging of embedded interfaces with multislice ptychography

Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Jianhua Zhang, Cong Su, Salman Kahn, Huaidong Jiang | Summary: We demonstrate the application of multislice ptychography to a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set. The propagation from the top flake, through the interface, to the bottom flake is […]

Three-dimensional imaging of buried heterointerfaces

Kavli Affiliate: Alex Zettl | First 5 Authors: Colum M. O’Leary, Haozhi Sha, Jianhua Zhang, Cong Su, Salman Kahn | Summary: We report three-dimensional (3D) structure determination of a twisted hexagonal boron nitride (h-BN) heterointerface from a single-view data set using multislice ptychography. We identify the buried heterointerface between two twisted h-BN flakes with a […]
