Welcome to the Nature Communications Editors’ Highlights webpage on condensed-matter physics. Each month our editors select a small number of Articles recently published in Nature Communications that they believe are particularly interesting or important.

The aim is to provide a snapshot of some of the most exciting work published in the area of condensed-matter physics at Nature Communications.

Make sure to check the Editors' Highlights page each month for new featured articles.

Quantum Hall phases have chiral edge modes, which could be used to explore and exploit the quantum properties of electrons. Interactions in these edge states lead to relaxation and decoherence, hindering any realistic exploitation. Here the authors observe spectroscopically the decay and revival of the excitation created by injection of an electron into the edge mode. Their results confirm phase-coherent transport and quantify the effect of dissipation-induced decoherence.

Conventional qubit readout methods in silicon spin qubits destroy the quantum state, precluding any further computations based on the outcome. Here, the authors demonstrate quantum non-demolition readout using a second qubit of the same kind, making for a scalable approach.

The Dirac spin liquid is a candidate description for the strongly correlated behaviour of some quantum magnets. Song et al. study the symmetry dependence physics of monopole excitations and argue that the lattice-dependent consequences for magnetic ordering may provide a unifying picture for 2D quantum magnetism.

One of the proposed explanations for the unusual pseudogap behaviour of cuprate superconductors is the formation of an electron nematic phase. Murayama et al. find magnetic anisotropy in the pseudogap regime of HgBa2CuO4+δ, providing evidence for anomalous nematic ordering.

Most theoretical studies of open quantum systems make several simplifying approximations but experimental devices, and some natural systems, now operate in regimes where those methods break down. Lambert et al. introduce a tractable approach to the spin-boson model without relying on the Born, Markovian and rotating wave approximations.

Strong correlation effects in metals lead to unconventional emergent behavior that depends on the nature of interactions at the microscopic scale. Deng et al. identify distinct signatures of the so-called Mott and Hund regimes, which may guide the theoretical understanding of correlated materials.

The boundaries of fractional quantum Hall states can host multiple, interacting one-dimensional edge modes, which test our understanding of strongly interacting systems. Here the authors observe the edge-mode equilibration transition that was predicted for the ν=2/3 fractional quantum Hall state.
