Cooling the motion of mechanical resonators to the ground state and subsequent advances in cavity optomechanics have been made possible by resolved-sideband cooling — an atomic-physics-inspired technique — first demonstrated in a 2008 Nature Physics paper.
A new measurement from the LHCb experiment at CERN's Large Hadron Collider impinges on a puzzle that has been troubling physicists for decades — namely the breaking of the symmetry between matter and antimatter.
A model describing spin-dependent conduction in metals underpins modern magnetic technologies. Magnetotransport under the fundamental conditions of this model has now been probed experimentally.
The traditional approaches to quantum information processing using either discrete or continuous variables can be combined in hybrid protocols for tasks including quantum teleportation, computation, entanglement distillation or Bell tests.
Nonlocal, nonlinear interactions of optical beams can be described by the Newton–Schrödinger equation for quantum gravity, offering an analogue for studying gravitational phenomena.
A scanning tunnelling microscopy study of monolayer FeSe on strontium titanate reveals that this intriguing system has a plain s-wave pairing symmetry.
Interacting optical wavepackets in the presence of a thermal optical nonlinearity are described by the same mathematics as the gravitational self-interaction of quantum wavepackets, providing a way of emulating gravitational phenomena in the lab.
The formation of vortex arrays in rotating Fermi gases is not limited to ultracold gases but may be relevant in nuclei and neutron stars, so it is important to be able to calculate their properties in a realistic fashion.
Radiation–matter interactions can become highly nonlinear when using high-intensity X-ray free-electron lasers. Under such conditions, it is shown that nonlinear Compton scattering has an anomalous redshift, whose origin remains unclear.
An interferometric measurement based on high-harmonic generation now provides direct access to the electron wavefunction during field-induced tunnelling.
Using post-selection and electromagnetically induced transparency in a cold atomic gas it is now possible to generate a strong nonlinear interaction between two optical beams, bringing nonlinear optics into the quantum regime.
Due to its structural simplicity, iron selenide is an attractive system for understanding the electronic mechanism for superconductivity in iron-based materials. A theoretical study now examines the influence of magnetic frustration in this system.
Systems exhibiting slow relaxation to equilibrium are often characterized in terms of an effective temperature arising from a modified fluctuation–dissipation theorem. Single-molecule experiments provide direct evidence for the validity of this idea.
