The observation of surprisingly large thermal Hall ratios in a growing number of mainly oxide-based insulators is a major puzzle and raises the question about potential mechanisms that can induce a thermal Hall effect in materials with dominant charge-neutral heat carriers. Here, the authors report the finding of comparable thermal Hall ratios in a series of charge-compensated topological insulators and discuss this observation in the context of a recent proposal that a thermal Hall effect can result from skew scattering of phonons on charged defects.

Phonons that have angular momentum and propagate in crystals are known as chiral phonons. The authors demonstrate the selective observation of chiral phonons in -quartz, the most typical chiral crystal, by circularly polarized Raman spectroscopy. They clarify the Raman tensors of the chiral phonons verifying the angular momentum conservation law in the Raman process, involving photons and the chiral phonon. This study suggests the possibility of controlling the angular momentum and propagation direction of chiral phonons via the Raman process.

Half-polarized neutron diffraction is used to measure the microscopic local magnetization density in the prototypical Kitaev material -RuCl, aiding in the determination of the elusive low-energy Hamiltonian. The magnetization density around each Ru ion is seen to be anisotropic, with hybridization resulting in a significant fraction of the moment associated with Cl atoms. First-principles calculations that take into account both the spin and orbital magnetization via Wannier functions elucidate the origin of the anisotropy.

Geometric frustration, magnetic anisotropy, and reduced dimensionality are responsible for the plethora of magnetic phases observed in the quantum antiferromagnet CsCoB. Among them are a commensurate magnetization plateau, a longitudinal spin density wave, and an incommensurate spin-fan structure. Even more unusual is the excitation spectrum. It is an hierarchy of successive bound states of fractional kink quasiparticles. To understand this rich physics, one has to know the spin Hamiltonian, and that can only be determined in high-field spectroscopic measurements.

Fractionalized excitations arise in many exotic phases of matter. Signatures of these quasiparticles are broad continua in linear response, hard to distinguish from other sources of broadening. The authors explore here excitations of emergent one-dimensional structures within pyrochlore magnets, demonstrating how nonlinear spectroscopy can be used to obtain sharp signatures of both fractionalized spinon and conventional magnon excitations. Varying the polarization of the probe fields enables either spinons or magnons to be observed and enables extraction of microscopic Hamiltonian parameters.

Amperean superconductivity is stemming from attractive effective electron-electron interactions mediated by a transverse gauge field. Amperean superconductivity has been recently proposed to occur at temperatures on the order of 1 K in two-dimensional electron gases embedded inside deep subwavelength optical cavities. Here, the authors generalize the microscopic theory of cavity-induced Amperean superconductivity to the case of graphene and then argue that this superconducting state cannot be achieved in the deep subwavelength regime.

Flat bands of surface states in noncentrosymmetric superconductors accompanied by a full gap in the bulk would be an alternative route to a strongly interacting two-dimensional Fermi system. They could provide a robust platform for quantum computation. Here, the authors explore a way to stabilize such bands in the entire surface Brillouin zone by introducing an additional spin-rotation symmetry that forces the direction of the spin-orbit-coupling vector not to depend on the momentum component, normal to the surface.

Ferrotoroidic order refers to a spontaneous vortex arrangement of magnetic dipoles, which has recently been established as the fourth primary ferroic state of matter. Thus far, ferrotoroidic order has been studied extensively in insulators, but much less investigated in metallic materials. Here, the authors demonstrate the visualization of ferrotoroidic domains in metallic NdB by spatial distribution measurements of optical second harmonic generation (SHG). This study will stimulate research on unique functionalities of ferrotoroidic order in metals, such as an electric current induced domain switching.

A vast landscape of topological phases of matter with emergent quasiparticles has been explored in the past two decades, but the majority of them are 2D or 3D in essence and far fewer 1D counterparts are known to exist. Here, first-principles calculations reveal a multitude of topological fermions near the Fermi level in the quasi-one-dimensional alloy VGa, which becomes a multigap nodeless superconductor below 3.6 K, raising the possibility of realizing topological superconductivity in this quasi-1D system.

Amperean superconductivity is stemming from attractive effective electron-electron interactions mediated by a transverse gauge field. Amperean superconductivity has been recently proposed to occur at temperatures on the order of 1 K in two-dimensional electron gases embedded inside deep subwavelength optical cavities. Here, the authors generalize the microscopic theory of cavity-induced Amperean superconductivity to the case of graphene and then argue that this superconducting state cannot be achieved in the deep subwavelength regime.

Flat bands of surface states in noncentrosymmetric superconductors accompanied by a full gap in the bulk would be an alternative route to a strongly interacting two-dimensional Fermi system. They could provide a robust platform for quantum computation. Here, the authors explore a way to stabilize such bands in the entire surface Brillouin zone by introducing an additional spin-rotation symmetry that forces the direction of the spin-orbit-coupling vector not to depend on the momentum component, normal to the surface.
