The anomalous Nernst effect (ANE), in which a thermal gradient drives a transverse charge current, can have both extrinsic and intrinsic origins. The intrinsic ANE should be enhanced when the Fermi level is in close proximity to Weyl points in the band structure. Magnetic Heusler alloys allow for tuning both the topology of the band structure and the position of the Fermi level. Here, the authors show that this tunability can be used to enhance the intrinsic ANE in epitaxial Heusler alloy thin films.

The mechanism responsible for the generation of optically induced spin currents upon femtosecond laser-pulse excitation of ultrathin ferromagnetic layers is still a heavily debated topic. In this paper, the authors study the phase of spin-current induced terahertz spin waves in noncollinear bilayer structures to probe spin currents in Fourier space. They measure a significant laser-pulse energy dependence of the spin-wave phase, which is quantitatively consistent with a spin current that is proportional to the time derivative of the magnetization.

Supercurrent transport requires vortices in superconductors to be pinned by material defects. Vortices are trapped in minima of the pinning potential landscape, and one has to determine what fraction of this landscape comes with a positive curvature. Such a curvature analysis is done by studying the Hessian matrix of the landscape. The authors find the stable area fraction to be unexpectedly low (yellow color in the figure). In particular, for Gaussian random landscapes it is . The results offer new hints for optimizing pinning landscapes. Their transdisciplinary application to natural landscapes exhibits a surprising universality.

The emergence of topological superconductivity and Majorana bound states in superconductor nanowire structures relies on a large induced topological gap, usually assumed to require strong coupling between superconductor and nanowire. However, strong coupling also brings detrimental effects such as the need for large critical Zeeman fields and the emergence of trivial zero-energy states. This work demonstrates that the aforementioned problems can be drastically mitigated in the weak-coupling regime, while retaining the robust properties of topological superconductivity including large topological gaps.

The discovery of charge density wave (CDW) order in the kagome-lattice superconductor VSb is interesting because of the potential interplay between CDW and superconductivity. This paper demonstrates that the CDW order is associated with a sudden hardening of a longitudinal optical phonon mode at the CDW ordering wave vector, thus establishing that the wave vector dependent electron-phonon coupling must play an important role in the CDW order of VSb.

The discovery of the paramagnetic spin-triplet superconductor UTe has made a large impact on condensed matter physics. The multiple superconducting phases in UTe under pressure are a fingerprint of the spin-triplet superconductivity. Here, the authors study the physical properties of this material under pressure using Te nuclear magnetic resonance measurements. NMR Knight shift and nuclear spin-lattice relaxation rate measurements reveal that Kondo coherence and superconductivity simultaneously disappear, indicating the importance of the heavy-fermion state for the superconductivity.
