  • Watching a single molecule move calls for measurements that combine ultrafast temporal resolution with atomic spatial resolution; this is now shown to be possible by combining scanning tunnelling microscopy with lightwave electronics, through a technique that involves removing a single electron from the highest occupied orbital of a single pentacene molecule in a time window shorter than an oscillation cycle of light.

  • The interaction of a molecule with a specific surface has been shown to produce consistent unidirectional motion driven by voltage pulses. The mechanism can even facilitate the transport of molecular cargo.

  • Cognitive psychologist Gary Marcus researches language acquisition and the evolution of the brain at New York University. On the release of his latest book, Guitar Zero — a personal yet scientific investigation of how people become musical — he explains how a love of music and a computer game helped him to overcome a lack of rhythm and learn to play the guitar.

  • By using a pump–probe atomic force microscopy detection scheme, electron spin transitions between non-equilibrium triplet states of individual pentacene molecules, as well as the ability to manipulate electron spins over tens of microseconds, is demonstrated.

  • The near field of a terahertz wave confined to a scanning probe tip provides femtosecond atomic-scale forces that coherently modulate the switching probability of a molecule between two stable adsorption geometries.

  • A study of the electronic structure of molecular wires as a function of their length reveals strong coupling between electrons and molecular vibrations. The mechanism provides a means to coherently couple electronic levels by nuclear motion, and possibly to mechanically control electron transport in molecular electronics.

  • Resonant charge transport to and from molecules and their corresponding charge-state transitions are critical to understanding electrically driven processes. Here, the authors investigate the charge-state lifetimes of single molecules through NaCl films of 3 to 5 monolayers thickness.

  • Spin-polarized defects in 2D materials are attracting attention for future quantum technology applications, but their controlled fabrication is still challenging. Here, the authors report the creation and characterization of effective spin 1/2 defects via the atomically-precise generation of magnetic carbon radical ions in 2D WS2.

  • Time-resolved lightwave-driven scanning tunnelling spectroscopy is developed to investigate how the spin–orbit-split energy levels of a selenium vacancy within a WSe2 monolayer shift under phonon displacement. Ultrafast snapshots of the electronic tunnelling spectra reveal transient energy shifts up to 40 meV.
