Network experiment demonstrates converse symmetry breaking

Mon, 20/01/2020 - 00:00

Nature Physics, Published online: 20 January 2020; doi:10.1038/s41567-019-0742-y

An experiment with three alternating-current generators demonstrates converse symmetry breaking—a phenomenon whereby the system achieves frequency synchronization when its component systems are tuned asymmetrically.

Echo in a single vibrationally excited molecule

Mon, 20/01/2020 - 00:00

Nature Physics, Published online: 20 January 2020; doi:10.1038/s41567-019-0762-7

Following an impulsive laser excitation of a single molecule, a dispersed vibrational wave-packet is partially rephased by a second pulse, and a wave-packet echo is observed. This wave-packet echo probes ultrafast intramolecular processes in the isolated molecule.

Bioelectrical domain walls in homogeneous tissues

Mon, 20/01/2020 - 00:00

Nature Physics, Published online: 20 January 2020; doi:10.1038/s41567-019-0765-4

A detailed theoretical and experimental investigation of homogeneous cell tissues finds that they can undergo spontaneous spatial symmetry breaking through a purely electrophysiological mechanism.

Many-body physics with individually controlled Rydberg atoms

Mon, 20/01/2020 - 00:00

Nature Physics, Published online: 20 January 2020; doi:10.1038/s41567-019-0733-z

This Review Article outlines the techniques necessary for the manipulation of neutral atoms and making use of their interactions, when excited to Rydberg states, to achieve the goal of quantum simulation of many-body physics.

Dynein harnesses active fluctuations of microtubules for faster movement

Mon, 20/01/2020 - 00:00

Nature Physics, Published online: 20 January 2020; doi:10.1038/s41567-019-0757-4

The motor protein dynein is associated with microtubule force generation in the cell; how it interacts with cytoskeletal fluctuations is still an open question. Here the authors show that dynein can harness these fluctuations to generate power and move faster towards the minus-end of microtubules.

Negative representation and instability in democratic elections

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0739-6

In a mathematical model of democratic elections, electoral instability is shown to be linked to negative representation, which occurs when a shift in electoral opinions pushes the election outcome in the opposite direction.

Electromagnetically induced transparency at a chiral exceptional point

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0746-7

The optical analogue of electromagnetically induced transparency and absorption can be modulated by chiral optical states at an exceptional point, which is shown in a system of indirectly coupled microresonators.

Near-Earth magnetotail reconnection powers space storms

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0749-4

Magnetic reconnection in the near-Earth magnetotail is observed to power a space storm, although suppression of magnetic reconnection caused by the Earth’s magnetic dipole was expected close to Earth.

Spectromicroscopic measurement of surface and bulk band structure interplay in a disordered topological insulator

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0759-2

The authors develop a high-spatial-resolution photoemission technique to show variation of the energy of the Dirac point of approximately 50 meV. They also find an interplay between bulk and surface states.

Variational quantum unsampling on a quantum photonic processor

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0747-6

The variational quantum unsampling protocol provides a way to realize verification and inference of near-term quantum circuit outputs. This protocol is then experimentally verified on a quantum photonic processor.

From ferromagnets to electoral instability

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0761-8

An electoral model predicts that polarized and alienated voters lead to unstable elections, like phase transitions in an Ising model. Such physics-inspired models may help political scientists devise electoral reforms to quench instability.

Observation of exciton polariton condensation in a perovskite lattice at room temperature

Mon, 13/01/2020 - 00:00

Nature Physics, Published online: 13 January 2020; doi:10.1038/s41567-019-0764-5

Non-equilibrium Bose–Einstein condensation of exciton polaritons in chains of lead halide perovskite pillars can occur at room temperature. These condensates have long spatial coherence.

The cost of synchronization

Nature Physics, Published online: 08 January 2020; doi:10.1038/s41567-019-0735-x

Synchronization of biochemical oscillators that are responsible for biological rhythms costs free energy. This theoretical result suggests that part of the adenosine triphosphate molecules consumed by a Kai oscillator is necessary for synchronization.

Nature Physics, Published online: 08 January 2020; doi:10.1038/s41567-019-0781-4

The need to control and manipulate the properties of quantum materials has led to a burst of interest in their properties out of equilibrium. Understanding this regime represents an opportunity for theorists and experimentalists alike.
