    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).


  • One of the most considered applications for quantum-inspired algorithms is solving combinatorial optimization problems. In this manuscript, the authors benchmark several quantum-annealing-inspired algorithms against other state-of-the-art optimizers and quantum annealer, comparing their success probabilities and time-to-solution.

  • Laser-driven X-rays can provide ultrashort pulses of broadband light, well suited for femtosecond timescale absorption spectroscopy. Here the authors measure the extended X-ray absorption features of a copper sample using a laser wakefield accelerator, in a single shot; important for studying samples driven to extreme and non-equilibrium states.

  • Understanding how cancer cells regulate their size is still largely an open question. The authors propose a method to infer the division strategy of leukemia cells via live cell fluorescence labeling and flow cytometry measurements combined with a mathematical model based on size-dependent growth and division rates.

  • The bulk-boundary correspondence and the tenfold classification table are important concepts for topological insulators and superconductors as they determine the nature or absence of topological boundary states. Using generalized Su-Schrieffer-Heeger and Kitaev models, the authors demonstrate topological domain-wall states in the classes where topology is thought to be impossible.

  • Living in groups is a key survival strategy for biological systems, yet its dependency on environmental characteristics is not fully understood. Exploiting active colloids in controlled optical landscapes as a model system, the authors demonstrated that the spatial complexity of the environment determines both the size and stability of these groups.

  • The rupture of thin liquid films has mostly been studied for supported films, where the substrate creates ambiguity in identifying the processes at film level that lead to rupture. Focusing on spontaneous rupture, the authors portray the complete life-cycle of freely suspended films of pure liquid, corroborating that deterministic hole formation precedes the stochastic spontaneous rupturing of thin films.

  • While various photonic lattices with topologically nontrivial band structures have been realized, how to measure topological invariants in such systems with photon losses has not been clearly understood. We find that the topological winding number can be measured even in the presence of photon loss by generalizing the concept of the mean-chiral displacement originally developed for lossless systems.

  • 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.
