  • Plasma created nanoparticles have become a valuable technological product in many fields, from solar cells to pharmaceutical applications. The authors use self-excited dust density waves to study the properties of an electron depleted plasma containing nanodust particles, and show that a variation of particle size and concentration has only minor effects on the ion generation and density.

  • Porous media that display a gradient in the structure of their networks are common in nature, but the understanding of the drainage patterns in such media is still limited. We propose a theoretical framework that allows to better quantify these patterns, and we validate it both with experiments in 3D printed models and with numerical simulations.

  • Organic solar cells, despite their high power conversion efficiencies, suffer from open circuit voltage losses making them less appealing in terms of applications. Here, the authors, supported with experimental data on small molecule photovoltaic cells, relate open circuit voltage to photovoltaic gap, charge-transfer state energy, and donor-acceptor interfacial morphology.

  • Anomalous-diffusion identifies the departure of diffusive dynamics from the traditional Brownian-motion and is a signature feature of a large number of complex soft-matter and biological systems. This article reports an analysis of an easy to implement method to decide on the type of an apparent anomaly, even in the presence of localisation errors.

  • Accurate understanding of the dynamics of correlated quantum many-body systems is of interest in many fields. Here the authors explain the exchange–correlation induced red-shift and incipient roton feature of the dynamic structure factor of the warm dense electron gas in terms of electronic pair alignment model.

  • Berry curvature is the key component underlying various band geometric characteristics of solid state systems. Here, the authors investigate second-order susceptibility using perturbation theories and time-dependent simulations showing that the transverse optical response in insulators is governed by an interband Berry curvature dipole.

  • Dissipative optical solitons can exhibit bound states with exciting molecule-like interactions. This work demonstrates the reconfigurable switching of soliton molecular complexes beyond diatomic molecules in an ultrafast laser system, which provides novel perspectives in understanding soliton interactions and triggers potential applications in ultrafast science.

  • The study of topological defects in matter is a topic of extensive interest, but it remains challenging when it concerns non-equilibrium active matter. The authors experimentally and computationally demonstrate that obstacles immersed in a two-dimensional active liquid crystal can pin a type of defects and slow down the dynamics of nearby defects.

  • The classical picture of cyclotron resonance fails to describe the interaction between large-amplitude plasma waves and low-energy particles. The authors identify anomalous resonance, or nonlinear modification of the classical resonant condition by strong wave field, by ultrafast spacecraft measurements that are consistent with test-particle simulations.

  • Light-matter interaction has been dominated by Born-Oppenheimer approximation for centuries. Here the authors proposed a light-matter interaction mechanism beyond this approximation, proposing stimulated phonon polariton-mediated light-matter interaction, showing further understanding and applications in the fields of optics/photonics and condensed-matter physics.

  • In topological physics, the bulk-boundary correspondence is of great interest in both Hermitian and non-Hermitian systems. This work unveils a similar universal modulation instability-rogue wave correspondence in integrable models, which may offer a way of better understanding the physics of nonlinear waves as well as of obtaining exact rogue wave solutions.

  • Relativistic theories brought the operational notion of time to the center stage of physics. Here, the authors show that effective unitary dynamics is not guaranteed if this notion is extended to quantum mechanics when relativistic corrections are considered in relational frameworks.

  • While it is widely believed that high-temperature superconductivity in cuprate materials arises from an intertwined interplay between charge and spin fluctuations, the microscopic coupling between charge and spin degrees of freedom still remains a mystery in these materials. Here, the authors profit from neutron scattering with superior beam focusing to probe the subtle spin-density wave order under uniaxial pressure, and demonstrate that charge and spin orders respond to the external tuning parameter in the same manner.

  • Space-time wave packets are optical pulses synthesized from light waves carrying strong correlations between their spatial and temporal degrees of freedom and show many anomalous behaviors such as superluminal propagation. In this study, the authors proposed a way of amplifying space-time wave packets by nonlinear optical parametric processes, which will widen the applications of the new optical wave packets.

  • It is intriguing but challenging to control the complex dynamics of topological defects that emerge in nonequilibrium spatiotemporal systems. Through an effective modelling this work explores a viable way to controllably vary the properties of persistent defect dynamics in self-propelled active smectics via the competition of activity and boundary confinements with different topology and geometry.

  • Chiral magnets are known to exhibit interesting electromagnetic properties that result from the coupling of electrons with nontrivial magnetic spin textures. Here, the authors demonstrate the interesting responses observed in the field-dependent longitudinal resistivity of a centrosymmetric magnet arises from domain morphology transitions.

  • With increasing temperature, current peaks in biased double quantum dots broaden and acquire a background stemming from the impact of environmental degrees of freedom such as phonons. Here, the authors measure this effect in an InAs heterostructure and demonstrate that it can be captured theoretically by two bosonic baths that model charge and current fluctuations.

  • Flat bands in twisted transition metal dichalcogenide semiconductors can host a wide array of strongly correlated states of matter. Here, the authors theoretically identify a rich phase diagram of charge-ordered states with exotic magnetic ordering emerging in a new class of honeycomb Moiré superlattices.

  • High harmonic generation in solids has been intensively studied for compact extreme ultraviolet light sources and for understanding of the inner workings of solids. In this study, the authors conducted polarization-resolved nonlinear spectroscopy of silicon with numerical calculations and uncovered the significant influence of van Hove singularities on the processes of high harmonic generation.
