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.

The fractional quantum anomalous Hall effect occurs when the Hall resistance in a material is quantized to fractional multiples of the fundamental unit h/e^{2} at zero magnetic field. Observing the effect in a system consisting of a combination of five-layer graphene and hexagonal boron nitride enriches the family of topological matter phases, and opens up new opportunities in quantum computation.

Implantable electric pacemakers save millions of lives worldwide, but they aren’t perfect. A proof-of-concept study shows that using light to regulate a heartbeat might be a better option than existing strategies.

A method for configuring light-trapping devices promises better optical nanodevices by amplifying light and enhancing the emission efficiency of luminescent nanomaterials — without the need for complex technology upgrades.

Maxwell’s demon refers to extracting a resource through measurement in a system, which for a quantum system can be done in a completely energy-conserving way. The authors present such a Maxwell’s demon method of subtracting bosonic energy of excited qubits for Janes-Cummings interactions to generate an out-of-equilibrium state.

Integer and fractional quantum anomalous Hall effects in a rhombohedral pentalayer graphene–hBN moiré superlattice are observed, providing an ideal platform for exploring charge fractionalization and (non-Abelian) anyonic braiding at zero magnetic field.

Exploring the impact of higher-order interactions in swarmalator systems, the authors analyze a model with pairwise and higher-order interactions, revealing four collective states. They find that even with predominantly repulsive pairwise interactions, elevated higher-order interactions sustain correlation among the swarmalators and minute fractions of higher-order interactions induce abrupt transitions between states.

Lattice gauge theory, a subset of gauge theory, has been successfully applied to a range of quantum systems allowing for the investigation of localised phenomena within these systems. Here, the authors consider a non-Hermitian lattice model observing a quantum disentangled liquid state that exists in both the localised and delocalised phases.

Ageing is a non-linear, irreversible process that defines many properties of glassy materials. Now, it is shown that the so-called material-time formalism can describe ageing in terms of equilibrium-like properties.

In 2023, a number of experiments on trilayer 2D structures uncovered new exciton states that have an electrically-tunable dipole moment and show a quantum many-body phase diagram.
