Tuning the Lifetime and Spectral Readout of Single-Atom Magnets with a Vector Magnetic Field

Abstract Magnetic atoms on insulating films are promising candidates for information storage at the atomic scale, but practical operation requires their magnetic lifetimes and readout to be controllable. Here, we study holmium (Ho) single-atom magnets on MgO using electron spin r...

Discovery and Manipulation of a Single Polaron in a Monolayer Mott Insulator

Abstract Polarons are quasiparticles composed of excess electrons and local lattice distortions that are crucial for understanding many-body physics. However, atomic-scale observation and manipulation of an intrinsic polaron in strongly correlated systems still remain elusive. He...
