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.

“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.

Energy and charge transfer processes like Interatomic Coulombic Decay (ICD) play an important role in the relaxation of excited atoms or molecules in dense media such as biological tissue. Here, we present a method to experimentally determine the site-specific efficiency of the ICD process, which is in quantitative agreement with theoretical calculations.

It is established that topological spin textures are a rich source for emergent physical properties; it remains a major challenge, however, to unravel their local structure and topological connections. Here, the authors apply X-ray vector magnetic tomography to gain insight into the magnetic structure near Bloch points at permalloy microstructures and identify several topological monopoles and dipoles within the domain wall core.

For decades hole dynamics were thought to be invisible in the transient spectroscopy of quantum dots. Here, the authors use a combination of time and frequency resolution of 2D electronic spectroscopy to reveal previously unobserved hole dynamics and rationalize these dynamics from a conceptual transition from continuum to atomistic theories of quantum dot excitonics.

Borophene, a single layer of boron atoms, has many of the exotic properties of its better-known cousin graphene. Here, the authors use ab initio calculations to understand the atomic origin of the tilt in the two-dimensional Dirac cone of 8Pmmn borophene, thereby suggesting atomic substitutions to vary the tilt.

Realising a topological superconductor with non-Abelian excitations is a central goal for the development and application of topological qubits. Here, the authors theoretically predict the emergence of intrinsic non-Abelian topological superconductivity that occurs when a ‘maximal’ twist angle of 30 degrees is introduced between two layers of a topologically trivial spin-triplet valley-singlet superconductor.

Motivated by the recent discovery of superconductivity in infinite layer nickelates, the authors study the correlation and temperature phase diagram of LaNiO₂ and NdNiO₂, using embedded DMFT combined with DFT. Their study offers insight into the low-energy physics of the paramagnetic and magnetic states, shedding some light on the mechanism of superconductivity and lack of magnetic order in these systems.

Capillary rise is a process whereby a liquid spontaneously rises against gravity within a narrow space due to capillary forces; but even though it is a well-understood phenomenon in smooth channels, predictive models to account for surface roughness are lacking. Here, the authors develop a theory of capillary rise in textured channels, supported by simulations and experiments, demonstrating the complex interplay between channel width, texture and wettability.
