  Exploiting disorder to probe spin and energy hydrodynamics

  Probing strongly interacting quantum systems with high spatial resolution can be challenging. An experiment now uses disorder in nuclear spin chains as a local probe to investigate spin and energy hydrodynamics.

  Critical prethermal discrete time crystal created by two-frequency driving

  Time-crystalline order appears in periodically driven systems with broken time-translation symmetry. Now, a protocol based on pulse drives of different frequencies is used to create and continuously observe time crystals with long lifetimes.

  Singlets singled out

  The state that forms at low temperatures in a quantum antiferromagnet on a kagome lattice has been debated for decades. Nuclear magnetic resonance has now shown the gradual emergence of entangled spin singlets in a disordered kagome antiferromagnet.

  Spin currents go nuclear

  Generating pure spin currents is a necessary part of many spintronic devices. Now there is a new mechanism for doing this, utilizing nuclear spin waves.

  Experimentally probing topological order and its breakdown through modular matrices

  Fundamental fingerprints of topological orders may be characterized uniquely and purely by experimental means. Here the authors provide a proof of principle demonstration using interferometric measurement in a two-dimensional lattice system.

  Para-hydrogen raser delivers sub-millihertz resolution in nuclear magnetic resonance

  A method for narrowing the NMR linewidth of specific molecules to the sub-millihertz range—two orders of magnitude below the natural linewidth—could open up new avenues for molecular characterization.

  Few-second-long correlation times in a quantum dot nuclear spin bath probed by frequency-comb nuclear magnetic resonance spectroscopy

  Using a frequency-comb nuclear magnetic resonance spectroscopy technique it is possible to probe the fluctuations in the nuclear spin bath of a self-assembled quantum dot and reveal long nuclear spin correlation times over one second.

  External high-quality-factor resonator tunes up nuclear magnetic resonance

  Reducing the signal-to-noise ratio is a never-ending challenge for many types of experiments. Now, improved ratios are reported for nuclear magnetic resonance set-ups combining an external high-Q resonator and a low-Q input coil.

  Sensing and atomic-scale structure analysis of single nuclear-spin clusters in diamond

  Being able to sense nuclear spin dimers is an important next step towards single-molecule structural analysis from NMR measurements. Now the sensing of a single ¹³C–¹³C nuclear spin dimer near a nitrogen–vacancy centre in diamond is reported, together with a structural characterization at atomic-scale resolution.

  Harnessing nuclear spin polarization fluctuations in a semiconductor nanowire

  Ensembles of nuclear spins display thermal fluctuations—spin noise—that interfere with nuclear magnetic resonance measurements of samples below a threshold size. Experiments on nanowires show that by monitoring spin noise in real time and applying instantaneously adjusted radiofrequency pulses, spin polarization distributions that are narrower than the thermal distribution can be obtained.

  Long live the spin

  A technique for protecting out-of-equilibrium nuclear spin states from thermalization while offering a route to converting them into observable NMR signal is an important contribution to a field that welcomes every bit of extra signal.

  Accessing long-lived nuclear singlet states between chemically equivalent spins without breaking symmetry

  Short nuclear spin–lattice relaxation times have long been a challenge for magnetic resonance imaging. The alternative of using long-lived nuclear spin states has so far required symmetry breaking, but a method of controlling these states without breaking the symmetry of the spin system has now been demonstrated.
