Wavefront shaping can reduce uncertainties due to measurement noise through disordered media—key to many imaging applications. Optimal precision can be achieved using light fields that are eigenstates of an operator related to the medium’s scattering matrix.
Starting from a strongly correlated state, with highly non-Gaussian correlations, a Gaussian state can emerge dynamically over time. Experiments with ultracold atoms show how the mixing between phase and density fluctuations plays the crucial role.
Characterizing the epithelial tissue of a shape-shifting marine animal as an integrated composite material reveals a ductile-to-brittle phase transition that captures how the tissue responds to failure.
In twisted bilayer graphene, the moiré potential, strong electron–electron interactions and a magnetic field conspire to split the flat band into topologically non-trivial subbands.
Resonant excitation of phonons by a laser pulse switches the magnetization of a thin yttrium iron garnet film. This particular combination of longitudinal optical phonons results in a quadrupolar pattern, but this could be tailored in the future.
Measurements of a superconducting infinite-layer nickelate show that its upper critical field is largely isotropic despite its quasi-two-dimensional structure. This indicates that, unusually for layered oxides, the superconductivity is Pauli-limited.
Strong quadratic coupling between the motion of a membrane and the energy states of a qubit enables the creation of a non-classical energy-squeezed state in the mechanical oscillator.
In a beam-driven plasma wakefield accelerator, the energy spread of an electron bunch is reduced with respect to the plasma entrance, which is achieved through setting a positive energy chirp that rotates the bunches’ longitudinal phase space.
Momentum-space transport behaviour studied in a quench-cooled isolated atomic Bose gas shows a self-similar scaling character, implying the existence of a far-from-equilibrium universality class.
Neutron-scattering measurements on the magnetically ordered triangular-lattice compound FeI2 reveal a dispersive band of mixed dipolar–quadrupolar fluctuations just above its ground state—a quantum excitation without a classical counterpart.
A periodically driven Floquet quantum many-body system initially prepared in a far-from-equilibrium state may exhibit prethermalization: that is, before reaching its thermal equilibrium the system first relaxes to a long-lived quasistationary state.
Majorana bound states should appear at both ends of a nanowire if it is in the topological regime. This paper reports that, in many cases, zero-bias conduction peaks only occur on one end of the wire, which casts doubt on whether they are Majoranas.
