Revived interest in proton-boron fusion has been fuelled by new laser matter interaction schemes with several possible applications. The authors report on a tabletop laser experiment that observes proton-boron fusion with an emphasis on the secondary cross-section peak around 150 keV.

The generation of spin-current is integral for the successful development of spintronic devices however the orbital counterpart is also expected to be potentially advantageous. Here, using Ni/Ti bilayers, in combination with tight binding calculations, the authors investigate the spin torque efficiency that occurs as a result of the orbital Hall effect, observing that orbital currents can propagate over longer distances than the spin currents.

The single-photon isolator is in high demand for optical communications and optical information processing in the quantum regime, but the noise is still a limitation. Here, the author theoretically propose a noiseless single-photon isolator scheme and demonstrate experimentally using hot atoms.

Magnetic molecules have chemically tunable electronic states that could be used for quantum technologies, but they are often surrounded by a nuclear spin bath causing decoherence. In this study, the authors experimentally investigate the electron-nuclear coupling approaching the clock transition and develop a simple theoretical model which gives a good qualitative understanding of the observed dynamics.

Active systems made of self-propelled units are widespread in nature, and Active Brownian particles (ABPs) are one of the simplest such system The authors theoretically and numerically investigate the collective assembly of ABPs finding a new re-entrant phase that enables motility-induced phase separation, which is dependent solely on activity.

Understanding the interaction of active matter with the random environment is relevant to the navigation of living entities within disordered media. This study introduces a minimal model of active particles that are repelled by both each other and the randomly distributed obstacles to reveal new chiral modes of collective patterns as a function of the quenched noise due to the stochastic nature of the environment.

Third-harmonic generation frequency combs grant telecom pump laser sources the direct and simultaneous access to both the near infrared and the visible spectral regions. The authors model the broadband and temporally dispersive dual-comb generation, and identify conditions for accessing a regime supporting two distinct and coexisting cavity solitons.

Current Rydberg quantum processors suffer from limitations in fidelity and scalability. Here, the authors address these limitations by proposing highly controllable multi-qubit operations that utilize the Fermi scattering of Rydberg electrons trapped in an optical lattice.

Precise modelling of solar cells devices under various conditions is essential to guide improvements in optimisation and performance of future technologies. Here, the authors present a holistic numerical model, verified with real-world data of thin-film CIGS modules, that can conduct loss analysis and predict the energy yield of thin film solar cells.

Electron-phonon coupling plays a fundamental role in the properties of conventional superconductors and is typically understood using BCS theory. Here, the authors study electron-phonon dynamics in the weak-coupling regime of Eliashberg theory identifying the similarities and differences between the two models in the dirty limit.

Fast and high-resolution Fourier transform spectrometers are indispensable for cutting-edge infrared spectroscopy. In this study, the authors employed a newly-designed fast-rotating retroreflective, broadband delay line demonstrating fast dual-comb spectroscopy with a single mid-infrared optical comb from a quantum cascade laser emitting at 8 micrometers.

“Previous studies investigating the creation of optical frequency combs through parametric modulation of microresonators rely on lumped-element models that do not consider how the modulations are spatially distributed. The current study underscores the crucial role of these spatial distributions in SNAP bottle microresonators, particularly in producing optical frequency combs with low repetition rate.

Spin dynamics induced by intense terahertz pulses are commonly observed by magnetooptical effects. Here, we show that magnetorefractive effect provides a second-harmonic magnon signal whose amplitude is comparably strong with the linear component, making it an efficient probe for detecting the inherent nonlinear spin dynamics in orthoferrites.
