    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).


  • Photonic Ising machines exploit the parallelism and high propagation speed of light to solve combinatorial optimization tasks. The authors propose and demonstrate a photonic Ising machine with a fully reconfigurable optical vector-matrix transformation system and a modified algorithm based on simulated annealing, solving 20 and 30-spin Ising problems with high ground state probability.

  • Many excitable systems share a common feedback motif, but how such feedback acts on biomechanical systems remains largely unexplored. By extending the cellular vertex models to incorporate mechanochemical feedback and excitability, the authors explore how cellular mechanics and geometry regulate the propagation of active stresses in excitable media.

  • The advent of non-Hermitian optics carries new possibilities in manipulating optical response, offering alternative ways to enhance the quantum coherence of plasmonic resonances. Based on a theoretical model, the authors calculate a quantum yield enhanced by two orders of magnitude at room temperature, achieved by integration of a plasmonic antenna in a photonic cavity operated at a chiral exceptional point.

  • Since 1974, it was theoretically postulated that black holes, despite their name, emit radiation with a spectrum like that of a black body. Utilizing surface gravity water waves to emulate black hole physics, the authors reveal the emergence of a logarithmic phase singularity analogous to that predicted by Hawking in black holes, whose energy distribution associated with the singularity results in a Fermi-Dirac distribution instead of the familiar Bose-Einstein statistics of the Hawking radiation.

  • Epsilon-near-zero materials are promising to realize ultrafast all-optical devices, but their integration into photonic chips requires simultaneously wide broadband operativity, low-losses and Si-compatiblity. The authors propose a Si-compatible multilayer metamaterial capable of all-optical switching response times of few hundred femtoseconds.

  • Magnetic frustration of spins often leads to nontrivial spin textures and anomalous Hall responses, but typically below the magnetic transition temperature. The authors observe a giant unconventional anomalous Hall conductivity in the triangularlattice antiferromagnet PdCrO2 well above its Neel temperature, attributed to spin cluster skew scattering.

  • Steady-State Microbunching (SSMB) is emerging as a new concept for accelerator-based light sources to meet demands for high average power radiation at short wavelengths. The authors present findings from a proof-of-principle experiment that agree with theoretical expectations in multiple aspects, laying the foundation for the future realization of SSMB.

  • When a pulsed laser interacts with tissue, the molecules in the sample get excited to a higher energy state and relax either nonradiatively, leading to thermal damage, or via de-excitation processes, frequently associated with photodamage. Here, the authors explore how different photodamage mechanisms unfold across a spectrum of intense near-infrared femtosecond pulses.
