Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.
Local thermodynamic measurements of a twisted transition metal dichalcogenide heterostructure reveal competition between unconventional charge order and Hofstadter states. This results from the presence of both flat and dispersive electronic bands, whose energetic ordering can be experimentally tuned.
A trilayer copper oxide superconductor, which exhibits the highest superconducting critical temperature as a function of the number of copper–oxygen planes, is shown to have unusual doped hole distribution and interaction between the planes.
The valley Hall effect offers an additional degree of freedom in 2D materials than can have implications for optoelectronic-based applications but measuring and controlling the effect is challenging. Here, the authors offer an approach to measure the valley Hall response using strain to induce variations in the particle density from which information on the Hall conductivity can be taken.
Performing quantum computing in the NISQ era requires reliable information on the gate noise characteristics and their performance benchmarks. Here, the authors show how to estimate the individual noise properties of any quantum process from the noisy eigenvalues of its corresponding quantum channel.
Acoustically driven spin control of silicon monovacancies can be used to measure the resonant properties and dynamical strain distribution in lateral overtone bulk acoustic resonators.
Emily Draper explains how to design and build electrochemical equipment for neutron scattering experiments with simple, at-hand components and techniques.

A nickel-based compound has shown evidence of a superconducting state at a temperature of 80 kelvin. The material bridges a gap between other nickelates and a notable class of superconductor containing copper.
