How to tame a giant oscillation

How to tame a giant oscillation, Published online: 22 April 2019; doi:10.1038/s41567-019-0510-z

Experiments and simulations show that trains of droplets in microfluidic networks undergo synchronized oscillations, and that strategies to prevent these oscillations can help maintain uniform distribution of red blood cells in microcirculation.

Violating Bell’s inequality with remotely connected superconducting qubits, Published online: 22 April 2019; doi:10.1038/s41567-019-0507-7

A deterministic violation of the Bell inequality is reported between two superconducting circuits, providing a necessary test for establishing strong enough quantum entanglement to achieve secure quantum communications.

Experimental characterization of two-particle entanglement through position and momentum correlations, Published online: 22 April 2019; doi:10.1038/s41567-019-0508-6

Single-particle resolved measurements in an ultracold-atom experiment reveal an intuitive picture of quantum correlations, providing strong constraints on the full density matrix of the two-particle system in the presence of interactions.

Topological triply degenerate point with double Fermi arcs

Topological triply degenerate point with double Fermi arcs, Published online: 22 April 2019; doi:10.1038/s41567-019-0502-z

In acoustic metamaterials, unconventional chiral quasiparticles exhibit multifold band degeneracy points, each carrying non-zero topological charges, giving rise to the topologically protected negative surface refraction.

Oscillating droplet trains in microfluidic networks and their suppression in blood flow

Oscillating droplet trains in microfluidic networks and their suppression in blood flow, Published online: 22 April 2019; doi:10.1038/s41567-019-0486-8

Droplet sequences in microfluidic networks are shown to form trains that oscillate between branches of the network. Control of this effect suggests a mechanism by which red blood cells might avoid certain pathologies by minimizing oscillations.

Deep-subwavelength features of photonic skyrmions in a confined electromagnetic field with orbital angular momentum, Published online: 15 April 2019; doi:10.1038/s41567-019-0487-7

Magnetic textures known as skyrmions have gathered much attention in recent years. It is now shown that focused vector beams can also give rise to photonic skyrmion-like structures.

Emergence of the geometric phase from quantum measurement back-action

Emergence of the geometric phase from quantum measurement back-action, Published online: 15 April 2019; doi:10.1038/s41567-019-0482-z

Following a closed evolution in the Hilbert space, the state vector of a quantum system accumulates a geometric phase factor. A series of weak measurements reveal the origin of this in the back-action of any quantum measurement.

Large and reversible myosin-dependent forces in rigidity sensing

Large and reversible myosin-dependent forces in rigidity sensing

Large and reversible myosin-dependent forces in rigidity sensing, Published online: 08 April 2019; doi:10.1038/s41567-019-0477-9

High-resolution experiments attribute surprisingly large forces to the molecular motors helping a cell sense its surroundings. A two-state theory interprets the contractile properties of these motors as emergent features of their collective behaviour.

Wound healing coordinates actin architectures to regulate mechanical work

Wound healing coordinates actin architectures to regulate mechanical work, Published online: 08 April 2019; doi:10.1038/s41567-019-0485-9

When a wound heals, different types of branched and bundled actin structure form, each designed to perform a specific function. Experiments and theory now suggest that the actin architecture depends on the stiffness of the cell’s surroundings.

Symmetry-enhanced discontinuous phase transition in a two-dimensional quantum magnet

Symmetry-enhanced discontinuous phase transition in a two-dimensional quantum magnet, Published online: 08 April 2019; doi:10.1038/s41567-019-0484-x

A phase transition often implies symmetry breaking in the system. However, an unconventional first-order phase transition is predicted, where higher-order symmetry than that of the underlying Hamiltonian emerges exactly at the phase boundary.

Stable coherent terahertz synchrotron radiation from controlled relativistic electron bunches, Published online: 08 April 2019; doi:10.1038/s41567-019-0488-6

A feedback loop based on chaos control theory permits the generation of stable and coherent terahertz radiation from relativistic electron bunches in synchrotron light sources.

An experimental study of living cells suggests that single myosin molecules are capable of generating unusually large forces. The observation is supported by a theoretical model — and demonstrates the complexity of in vivo force generation.

Two-dimensional skyrmion bags in liquid crystals and ferromagnets, Published online: 01 April 2019; doi:10.1038/s41567-019-0476-x

Structures containing multiple skyrmions inside a larger skyrmion—called skyrmion bags—are experimentally created in liquid crystals and theoretically predicted in magnetic materials. These may have applications in information storage technology.

If you were ever puzzled about the fact that the detectors at the Large Hadron Collider record huge datasets despite the tiny probability of two protons colliding, this is for you. Steven Goldfarb and Katarina Anthony connect the dots.

Large work extraction and the Landauer limit in a continuous Maxwell demon

Large work extraction and the Landauer limit in a continuous Maxwell demon, Published online: 01 April 2019; doi:10.1038/s41567-019-0481-0

A continuous version of the Maxwell demon is a machine that repeatedly monitors a system, but extracts work only on state change. Arbitrarily large quantities of work can thus be extracted, as demonstrated by DNA hairpin pulling experiments.
