This static high-pressure x-ray diffraction study of iridium investigates previous reports of a core-level crossing at 80 GPa, whereby the authors find no evidence for such a transition. Further computational investigations reveal that a core-level crossing does occur in iridium, but only at 400 GPa. In addition, the efficacy of bismuth as a pressure-transmitting medium is demonstrated, maintaining a uniaxial stress component in the sample below 2% up to 159 GPa.

Altermagnets are an unconventional type of magnetic state with various appealing properties, both from the fundamental and applied physics perspectives. By investigating the impact of spin-orbit coupling on these states, this work reveals that all altermagnets are intrinsically noncollinear and that their Zeeman splittings possess symmetry-protected nodal lines. These features endow altermagnets with a remarkable resilience against external magnetic fields.

The authors provide an analytic theory of the transport of magnetization in a set of interacting anisotropic spin chains. Even though these are many-body systems with diffusive transport on average, the full distribution that gives rise to that average is far from Gaussian – with fluctuations that, unlike conventional diffusion, are comparable to the mean. This is an example of how systems with the same hydrodynamics can belong to distinct dynamical universality classes.

Antiskyrmions, like skyrmions, are topologically protected magnetic quasiparticles, but exhibit greater stability and no transverse motion compared to skyrmions. This study employs calculations to investigate the polar layer stacking of two monolayers of a two-dimensional magnetic material CrI, which can lead to the emergence of antiskyrmions. Atomistic spin dynamics simulations demonstrate the realization of antiskyrmions in Mn-doped CrI and shows that their spin texture can be switched by ferroelectric polarization of the polar bilayer.

The magnetoelastic coupling of magnetic and elastic excitations enables the generation of elastic waves carrying angular momentum. In a quantum picture, this corresponds to a resonant conversion of magnons to chiral phonons and vice versa. This study showcases this conversion process using a simple and versatile experimental platform consisting of a metallic magnetic thin film on a crystalline substrate. These findings allow us to study the impact of crystal symmetry on angular momentum transport by phonons and investigate phononic birefringence.

The topological Hall effect (THE) is a Hall response that arises from the deflection of motion of charge carriers flowing through nontrivial spin textures. Here, the authors observe a significant THE and investigate its interplay with the spin-polarized topological surface states in a proximity-magnetized topological insulator/ferrimagnet heterostructure. Specifically, they demonstrate a sign change in THE via a top electrical gate as the Fermi level is tuned from the electron-doped to the hole-doped region of the gapped Dirac cone.

Topological magnon edge modes have been proposed for the realization of robust, low-loss spintronic devices. However, ubiquitous many-body interactions that do not preserve particle number significantly compromise their topological protection. The authors show here that these interactions can lead to significant edge mode damping, hybridization with bulk modes, and coupling between edge modes on opposite sides. These findings pose challenges for the experimental realization of topological magnon edge modes, but can be overcome by the application of large magnetic fields.

This work develops a systematic theoretical framework to determine the low-energy effective “diamagnetic” response associated with superconductivity and excitonic superfluidity in strongly interacting electronic models hosting isolated nearly flat bands. The results can be used to derive upper bounds on the transition temperatures for superconductivity and excitonic superfluidity without making any mean-field type approximations. The same theoretical framework can also be extended with very few modifications, to address questions related to ferromagnetism in flat bands and magnetic circular dichroism.

The eigenstate thermalization hypothesis (ETH) represents a cornerstone in the theoretical understanding of the emergence of thermal behavior in closed quantum systems. Here, the authors investigate to what extent the ETH holds for non-Hermitian Hamiltonians, relevant for open and monitored quantum systems, and come to the surprising conclusion that fluctuations are greatly enhanced, indicating the breakdown of thermalization.

The authors determine here the minimal spin Hamiltonian of manganese silicide from analysis of muon spin rotation experimental data measured in its helical and conical phases. The model includes Heisenberg and Dzyaloshinskii-Moriya interactions between the Mn nearest neighbors. In particular, information is derived on the orientation of the Moriya vector that cannot be inferred from the symmetry of the Mn-Mn bond. This result enforces constraints for future theoretical works, e.g., on the origin of the stability of the magnetic skyrmions phase.

The topological Hall effect (THE) is a Hall response that arises from the deflection of motion of charge carriers flowing through nontrivial spin textures. Here, the authors observe a significant THE and investigate its interplay with the spin-polarized topological surface states in a proximity-magnetized topological insulator/ferrimagnet heterostructure. Specifically, they demonstrate a sign change in THE via a top electrical gate as the Fermi level is tuned from the electron-doped to the hole-doped region of the gapped Dirac cone.

Topological magnon edge modes have been proposed for the realization of robust, low-loss spintronic devices. However, ubiquitous many-body interactions that do not preserve particle number significantly compromise their topological protection. The authors show here that these interactions can lead to significant edge mode damping, hybridization with bulk modes, and coupling between edge modes on opposite sides. These findings pose challenges for the experimental realization of topological magnon edge modes, but can be overcome by the application of large magnetic fields.

This work develops a systematic theoretical framework to determine the low-energy effective “diamagnetic” response associated with superconductivity and excitonic superfluidity in strongly interacting electronic models hosting isolated nearly flat bands. The results can be used to derive upper bounds on the transition temperatures for superconductivity and excitonic superfluidity without making any mean-field type approximations. The same theoretical framework can also be extended with very few modifications, to address questions related to ferromagnetism in flat bands and magnetic circular dichroism.
