    Communications Physics has a 2-year impact factor of 5.5 (2022), a mean decision times of 7 days to first editorial decision and 50 days to first post-review decision (2023).


  • The authors report about a proof-of-principle experiment that demonstrates the recovery of a Hydrogen plasma accelerator at the sub-nanosecond timescale. The result is obtained with a pump-andprobe setup and represent a step forward for the next-generation of compact high-repetition rate plasma-based accelerators.

  • Neural networks perform computations through finely tuned patterns of connections, but it remains unclear how these connections lead to specific computations. Here, the authors introduce a neural network that can perform computations while also being mathematically solvable, providing new insights into the link from connections to computation.

  • The authors study the collective behavior of ellipsoidal active particles, which is richer and less understood than that of their spherical counterparts. They find a variety of states such as cluster formation, local polar order, polar flocks, and disordered states, and obtain an analytical expression for the pair-distribution function, which allows a quantitative characterization of the system’s state.

  • Twisted monolayer-bilayer graphene has attracted intense interest due to its rich symmetry-broken states which can be tuned by an external electric field. Here, the authors determine the ground states at half-filling of the conduction band under opposite electric field and report on a symmetry-broken Chern insulator state with its Chern number closely related to the half-filling ground states.

  • Ising problems are ubiquitous in physics, hence the exploration of new methods to tackle Ising problems with large scale and dense connectivity is of great interest. The authors propose a variational autoregressive architecture with a message passing mechanism that uses the interactions between spin variables, while previous methods build on the correlations only.

  • Coherent perfect absorption allows to entirely dissipate the energy impinging on both single and multimode systems, but it typically does not allow for a control of the phase quadratures. Here, the authors implement coherent interferometric control of the phase quadratures in two strongly-coupled electromechanical nanoresonators.

  • Controlling microrobot movement in blood vessels is vital for medical treatments but is challenging due to red blood cells. This study combines simulations, experiments, and machine learning to demonstrate how hematocrit levels and robot geometry affect its locomotion characteristics in blood

  • A quantum dot-superconductor array can form a Kitaev chain which hosts Majorana zero modes at a sweet spot. The authors examine how to enhance the excitation gap of the Majorana zero modes, which is crucial for implementing topological quantum computing with enhanced protection.
