Imposing PT-symmetry and pseudo-Hermitian symmetry on an electric circuit with non-reciprocal couplings results in a complex morphology of degenerate eigenvalues that might yield new possibilities in sensing and dynamical engineering.
A biomolecular motor exploits a rigid-to-flexible transition of a protein tether, which allows thermal fluctuations to draw together vesicle membranes. This entropic motor helps traffic material into and around cells.
Although quantum spin liquids have long been theoretically studied, an experimental demonstration has remained challenging. An inorganic oxide presents an ideal candidate to realize this disordered state.
A quantum engineering technique powered by disorder offers access to local correlation functions down to single-site resolution in nuclear spin ensembles, allowing the study of both spin and energy hydrodynamics.
Calculations support experiments in predicting the existence and properties of point defects in solids but often do not correctly capture their details. A different method can significantly improve the prediction of defect structures and properties.
Atom trap trace analysis has emerged as a powerful technique for detecting trace radioisotopes of noble gases. The successful application of the method to a calcium isotope now opens the possibility of extension to other metal isotopes.
Levitated nanoparticles can now be cooled to the motional ground state in two dimensions. This advance could enable a new generation of macroscopic quantum experiments.
Developing tissues undergo collective cell movement and changes to their material properties, such as flow characteristics. Now tissue fluidity is linked to tissue growth.
The production of particle–antiparticle pairs in a vacuum — the Schwinger effect — requires extreme conditions that are out of reach of tabletop experiments. A mesoscopic simulation of this phenomenon has now been carried out in graphene devices.
The combination of magnetic and non-magnetic layers in (MnBi2Te4)(Bi2Te3) is predicted to produce topologically protected states on the surface. Experiments now show that the nature of the topmost layer controls the location of these states.
Time-varying photonics constitutes an emerging concept where a material’s time-dependence is used to achieve novel functionalities. A temporal double-slit-diffraction experiment demonstrates the feasibility of time-modulating materials to control light.
The strong interaction is modified in the presence of nuclear matter. An experiment has now quantified with high precision and accuracy the reduction of the order parameter of the system’s chiral symmetry, which is partially restored.
The study of complexity of unitary transformations has become central to quantum information theory and, increasingly, quantum field theory and quantum gravity. A proof of how complexity grows with system size demonstrates the power of a geometric approach.
The discovery of an unexpectedly large thermoelectric response in a 2D material establishes its power to probe the entropy carried by its charge carriers in the hotly debated strange metal phase.
