  • Landau damping and transit-time damping are known resonant wave-particle interactions in which energy is transferred from the wave to ions or electrons in the plasma. The authors study collisionless energy transfer in a plasma of deuterium and carbon atoms, observing that more energy is transferred to the heavier carbon ions, suggestive of a mass-dependence in the process.

  • While gender disparities in the science, technology, engineering, and mathematics (STEM) disciplines are widely noted, the citation gap is still understudied and awareness remains low. Here, we address citation inequity in physics and describe individual and collective mitigation initiatives, including the citation diversity statement.

  • This study extends the notion of the non-Hermitian skin effect to the regime where many-body interactions dominate single particle energetics, reminiscent of fractional quantum Hall systems. It reveals the emergence of a family of "skin cluster" states, with distinct forms such as vertex, topological, interface, extended, and localized skin clusters.

  • Light-induced superconductivity is a recent phenomenon where many aspects of the underlying physics are still to be fully understood. Here, the authors analyse coupled Ginzburg-Landau and Maxwell equations to investigate the dynamics of the quantum states when a superconductor is irradiated by a laser pulse.

  • Quantum spin liquids are a series of materials which exhibit an absence of magnetic order down to absolute zero and may have applications for data storage and memory. Here, using numerical simulations, the authors propose that the magnetic frustration in a quantum spin liquid may also lead to pronounced magnetocaloric effects near the quantum critical point with potential application as materials for refrigerants.

  • Kagome metals can house a complex interplay of competing phenomenon and there has been significant investigation into how to engineer the resultant properties, as well as understand the underlying physics. Here, the authors investigate the competition between charge density wave order and superconductivity for CsV3Sb5 using a combination of high-pressure and muon spin rotation measurements.

  • Measuring the in-plane mechanical stress in a taut membrane is challenging, but fundamental to basic research and practical applications, from engineering to tissues. Here, the authors propose an accurate measurement technique of the in-plane stress in thin films based on the speed of elastic waves measured through optical coherence tomography, and demonstrate it on a rubber membrane, common household plastic wrap, and leather skin of an Irish frame drum.

  • Authors introduce a new class of topological materials, namely projected topological branes that are holographic images of higher-dimensional topological crystals, and feature either emergent crystalline or aperiodic quasicrystalline order. They manifest bulk-boundary and bulk-lattice defect correspondences of parent crystals and open a realistic route to harness four and higher-dimensional topological crystals in three-dimensional world.

  • A central problem in magnetized fusion plasmas is to understand whether the plasma edge sustains a turbulent state and transitions to improved confinement. The authors simulate the detailed organization of turbulence from the primitive flux-driven kinetic equations including plasma-solid interaction and identify basic mechanisms which allow to cure the oft-reported shortfall of turbulence power in the plasma edge and to describe spontaneous onset of a transport barrier.

  • Quantum fluctuations stabilize dense self-bound macroscopic quantum states in quantum gases. This work places an Erbium dipolar ultracold atomic gas with dominantly attractive long-range interactions in a 1D periodic lattice, and uses interferometric techniques and numerical modeling to characterize the importance of beyond mean-field effects, revealing the emergence of spatially-extended and single-site localized (2D) droplets and signatures of an anisotropic 2D soliton.

  • Josephson junctions have applications in quantum circuits but producing and controlling the coupling between junctions is challenging. The authors characterize the electronic transport properties of two adjacent Josephson junctions, demonstrating short-range coherent coupling indicative of a nonlocal Josephson effect.

  • This study confirms that a classical channel model can be used for describing random fluctuations in LEO-to-ground quantum atmospheric channels. It shows that practical engineering designs for future QKD missions can be conveniently conducted using the verified channel model, and that deep learning can predict channel fluctuations.

  • Superconducting spintronics aims to utilise the interaction between magnetic order and superconductivity in order to enhance the performance of a spintronics-based device. Here, the authors experimentally investigate a superconducting spin valve and report a crossover from giant magnetoresistance to the superconducting spin-valve effect as function of material thickness.

  • A new class of topological systems has been recently discovered, it has been dubbed the Euler insulator and can manifest in two-dimensional systems. The authors present an experimental implementation for realizing the Euler insulator with 171Yb+ ion trapped by an electrode-surface trap where the topological indicators such as the Euler class, Wilson loop flow and entanglement spectrum for the theoretical and experimental models clearly show the presence of a fragile phase

  • Spin-triplet superconductors are expected to host topological excitations, which makes them potentially useful materials for future quantum technologies. Here, the authors theoretically report a triple point semimetal that, through triple point fermions, stabilizes an s-wave spin-triplet pairing distinct from conventional BCS and other multi-band superconductors.

  • Most bound quantum states in condensed matter systems emerge due to two-body interactions. Here, the formation of a stable three-particle bound state, induced by irreducible three-particle interactions in an antiferromagnetic spin ladder, is evidenced analytically and numerically for realistic material parameters.
