People’s potential

Frustration can be critical

Δευ, 30/09/2019 - 00:00

Nature Physics, Published online: 30 September 2019; doi:10.1038/s41567-019-0668-4

An unusual flavour of critical phenomena with a stable quantum critical phase of matter is observed in a strongly correlated material and linked to the underlying lattice structure.

Quantum-critical phase from frustrated magnetism in a strongly correlated metal

Δευ, 30/09/2019 - 00:00

Nature Physics, Published online: 30 September 2019; doi:10.1038/s41567-019-0666-6

A phase of quantum-critical behaviour is observed in a kagome lattice material. This arises from the interplay of strong interactions between electrons, and the frustration that arises both from the interactions and the lattice geometry.

Magnetic fields alter strong-field ionization

Δευ, 30/09/2019 - 00:00

Nature Physics, Published online: 30 September 2019; doi:10.1038/s41567-019-0653-y

Experiments with two counter-propagating laser beams report the observation that the photon momentum is shared between the electron and parent ion in strong-field ionization, which results from the photon’s magnetic field acting on the electron.

Author Correction: Enhancement of interlayer exchange in an ultrathin two-dimensional magnet

Quantum superposition of molecules beyond 25 kDa

Nature Physics, Published online: 23 September 2019; doi:10.1038/s41567-019-0663-9

Matter-wave interference experiments demonstrate quantum superposition of molecules consisting of up to 2,000 atoms—the heaviest objects to show this quantum behaviour to date. This provides a bound on potential modifications to quantum mechanics.

Semimetallic molecular hydrogen at pressure above 350 GPa

Δευ, 23/09/2019 - 00:00

Nature Physics, Published online: 23 September 2019; doi:10.1038/s41567-019-0646-x

The predicted metallization of hydrogen has long fascinated high-pressure physicists. Conductivity and spectroscopic measurements now reveal that above pressures of 350 GPa, hydrogen starts to conduct in a manner akin to a semimetal.

Femtosecond-resolved observation of the fragmentation of buckminsterfullerene following X-ray multiphoton ionization

Δευ, 23/09/2019 - 00:00

Nature Physics, Published online: 23 September 2019; doi:10.1038/s41567-019-0665-7

X-ray pump–probe experiments reveal that the molecular structure of C60 molecules substantially delays their fragmentation following photoionization. This may help to understand X-ray laser-induced radiation damage on molecules.

Floquet approach to <span class="stix">ℤ</span><sub>2</sub> lattice gauge theories with ultracold atoms in optical lattices

Δευ, 16/09/2019 - 00:00

Nature Physics, Published online: 16 September 2019; doi:10.1038/s41567-019-0649-7

An effective Hamiltonian exhibiting $${\Bbb Z}_2$$ Z 2 symmetry has been engineered by implementing a Floquet-based method on ultracold bosons in an optical lattice, providing a first step towards quantum simulation of $${\Bbb Z}_2$$ Z 2 lattice gauge theories with ultracold matter.

Kibble–Zurek universality in a strongly interacting Fermi superfluid

Δευ, 16/09/2019 - 00:00

Nature Physics, Published online: 16 September 2019; doi:10.1038/s41567-019-0650-1

The Kibble–Zurek mechanism, that is, the spontaneous formation of topological defects in a system crossing a continuous phase transition, is observed in a strongly interacting Fermi gas, where the underlying symmetry plays a crucial role.

Enhancement of interlayer exchange in an ultrathin two-dimensional magnet

Δευ, 16/09/2019 - 00:00

Nature Physics, Published online: 16 September 2019; doi:10.1038/s41567-019-0651-0

Few-layer magnetic materials sometimes show a different form of magnetism from their thicker equivalents. The authors contend that the mechanism is changes in the stacking order in the thin limit that modify the interlayer exchange interaction.

Engaged in gauge theory

Δευ, 16/09/2019 - 00:00

Nature Physics, Published online: 16 September 2019; doi:10.1038/s41567-019-0664-8

Two independent cold-atom experiments have demonstrated the building blocks for the quantum simulation of dynamical gauge fields — an advance that holds promise for our understanding of computationally intractable problems in high-energy physics.

The odd free surface flows of a colloidal chiral fluid

Δευ, 09/09/2019 - 00:00

Nature Physics, Published online: 09 September 2019; doi:10.1038/s41567-019-0603-8

A chiral fluid comprising spinning colloidal magnets exhibits macroscopic dynamics reminiscent of the free surface flows of Newtonian fluids, together with unique features suggestive of Hall—or odd—viscosity.

Dynamics of soliton crystals in optical microresonators

Δευ, 09/09/2019 - 00:00

Nature Physics, Published online: 09 September 2019; doi:10.1038/s41567-019-0635-0

A dissipative Kerr soliton crystal state is a temporally ordered regular ensemble of soliton pulses within a cavity. Chaotic driving of optical resonators enables the defect-free creation and dynamical characterization of these states.

Model oddity

Δευ, 09/09/2019 - 00:00

Nature Physics, Published online: 09 September 2019; doi:10.1038/s41567-019-0633-2

A model fluid comprising rotating magnetic particles behaves according to the equations of hydrodynamics, but for a few key differences due to broken mirror symmetry. The resulting active chiral fluid is characterized by parity-odd Hall viscosity.
