We investigate the radiation of optical angular momentum by a dipole gas under uniform magnetic field with an unpolarized source at its center. Conservation of angular momentum implies a torque on both the source and the surrounding environment. We study the separate spin and orbital contributions to the radiated angular momentum.

The Gottesman-Kitaev-Preskill (GKP) code is a promising bosonic quantum error-correcting code, encoding logical qubits into a bosonic mode in such a way that many physically relevant noise types can be corrected effectively. A particularly relevant noise channel is the pure loss channel, which the GKP code is known to protect against. In particular, it is commonly pointed out that losses can be corrected by the GKP code by transforming the losses into random Gaussian displacements through a quantum-limited amplification channel. However, implementing such amplification in practice is not ideal and could easily introduce an additional overhead of noise from associated experimental imperfections. Here, we analyze the performance of teleportation-based GKP error correction against loss in the absence of an amplification channel. We show that amplification is not required to perform GKP error correction and that performing amplification actually worsens the performance for practically relevant parameter regimes.

Black holes (BHs) traversing a dark matter cloud made out of a self-interacting scalar soliton are slowed down by two complementary effects. At low subsonic speeds, the BH accretes dark matter, and this is the only source of dragging along its motion, if we neglect the backreaction of the cloud's self-gravity. The situation changes at larger supersonic speeds where a shock appears. This leads to the emergence of an additional friction term, associated with the gravitational and scalar pressure interactions and with the wake behind the moving BH. This is a long distance effect that can be captured by the hydrodynamical regime of the scalar flow far away from the BH. This dynamical friction term has the same form as the celebrated Chandrasekhar collisionless result, albeit with a well-defined Coulomb logarithm and a prefactor that is smaller by a factor $2/3$. The infrared cutoff is naturally provided by the size of the scalar cloud, which is set by the scalar mass and coupling, whilst the ultraviolet behavior corresponds to the distance from the BH where the velocity field is significantly perturbed by the BH, which is determined by pressure effects. As a result, supersonic BHs are slowed down by both the accretion drag and the dynamical friction. This effect will be potentially detectable by future gravitational wave experiments as it influences the phase of the gravitational wave signal from inspiralling binaries.

We present a scheme for the charging of a quantum battery based on the dynamics of an open quantum system undergoing coherent quantum squeezing and affected by an incoherent squeezed thermal bath. We show that quantum coherence, as instigated by the application of coherent squeezing, is key in the determination of the performance of the charging process, which is efficiency-enhanced at low environmental temperatures and under a strong squeezed driving.

We consider the nonlinear Schr"odinger equation with nonlocal derivatives in a two-dimensional periodic domain. For certain orders of derivatives, we find a type of quasi-breather solution dominating the field evolution at low nonlinearity levels. With the increase of nonlinearity, the structures break down, giving way to Rayleigh-Jeans (or wave turbulence) spectra. Phase-space trajectories associated with the quasibreather solutions are found to be close to that of the linear system and almost periodic. We employ two methods to search for nearby periodic solutions (e.g., exact breathers), yet none are found. Given these distinguishing behaviors, we interpret this structure in the context of Kolmogorov-Arnold-Moser (KAM) theory.

We propose a scheme that generates period-doubled responses via periodically driving certain Hamiltonians hosting quantum many-body scars, akin to recent experimental observations in driven Rydberg atom arrays. Our construction takes advantage of an su(2) spectrum generating algebra associated with the static quantum-scarred Hamiltonian, which enacts a $ensuremath{pi}$ rotation within the scar subspace after one period of time evolution with appropriately chosen driving parameters. This yields period-doubled (subharmonic) responses in local observables for any choice of initial state residing in the scar subspace. The quasienergy spectrum features atypical $ensuremath{pi}$-paired eigenstates embedded in an otherwise fully thermal spectrum. The protocol requires neither a large driving frequency nor a large driving amplitude and is thus distinct from the prethermalization physics in previous investigations of the driven PXP model. We demonstrate our scheme using several spin-1/2 and spin-1 quantum scarred models possessing an exact su(2) spectrum generating algebra, as well as a symmetry-deformed PXP model, where the su(2) algebra is only approximate. Our results extend the class of models hosting quantum many-body scars that can be leveraged to yield time-crystalline behaviors under periodic driving.

Antiferromagnetic (AFM) thin films have been proposed as a promising material for manipulating perpendicular magnetic anisotropy (PMA) in ferromagnetic (FM) thin films. In this work, a series of epitaxially grown AFM/Co/Fe structures are investigated, in which the AFM layer is composed of fcc ${mathrm{Fe}}_{50}{mathrm{Mn}}_{50}$ and vertically expanded face-centered-tetragonal Mn films with distinct three-dimensional quadratic-type and two-dimensional layered spin structures, respectively. Our findings demonstrate that an individual AFM film in the composite AFM layer not only can enhance the long-range AFM ordering in its adjacent AFM neighbor but also can exert control over the neighbor's AFM spin structure; these modulation mechanisms subsequently induce PMA in an adjacent FM film. The research sheds light on the AFM proximity effects within the AFM composite layers and their profound influence on PMA induction in adjacent FM layers, offering essential insights for improving control over PMA with AFM layers.

Recently, unusual $ensuremath{pi}$ phase shifts in Little-Parks experiments performed on two systems derived from the layered superconductor $2Htext{ensuremath{-}}{mathrm{TaS}}_{2}$ were reported. These systems share the common feature that additional layers have been inserted between the $1Htext{ensuremath{-}}{mathrm{TaS}}_{2}$ layers. In both cases, the $ensuremath{pi}$ phase shift has been interpreted as evidence for the emergence of exotic superconductivity in the $1H$ layers. Here, we propose an alternative explanation assuming that superconductivity in the individual $1H$ layers is of conventional $s$-wave nature derived from the parent $2Htext{ensuremath{-}}{mathrm{TaS}}_{2}$. We show that a negative Josephson coupling between otherwise decoupled neighboring $1H$ layers can explain the observations. Furthermore, we find that the negative coupling can arise naturally assuming a tunneling barrier containing paramagnetic impurities. An important ingredient is the suppression of non-spin-flip tunneling due to spin-momentum locking of Ising type in a single $1H$ layer together with the inversion symmetry of the double layer. In the exotic superconductivity scenario, it is challenging to explain why the critical temperature is almost the same as in the parent material and, in the $4mathit{Hb}$ case, the superconductivity's robustness to disorder. Both are nonissues in our picture, which also exposes the common features that are special in these two systems.

Using large-scale density-matrix renormalzation group calculations and minimally augmented spin-wave theory, we demonstrate that the phase diagram of the quantum $S=frac{1}{2}phantom{rule{4pt}{0ex}}{J}_{1}$--${J}_{3}$ ferro-antiferromagnetic model on the honeycomb lattice differs dramatically from the classical one. It hosts the double-zigzag and Ising-$z$ phases as unexpected intermediaries between ferromagnetic and zigzag states that are also extended beyond their classical regions of stability. In broad agreement with quantum order-by-disorder arguments, these collinear phases replace the classical spiral state.

We introduce a classification of the radial spin textures in momentum space that emerge at the high-symmetry points in crystals characterized by nonpolar chiral point groups $({D}_{2},$ ${D}_{3},$ ${D}_{4},$ ${D}_{6},$ $T,$ $O)$. Based on the symmetry constraints imposed by these point groups in a vector field, we study the general expression for the radial spin textures up to third order in momentum. Furthermore, we determine the high-symmetry points of the 45 nonpolar chiral space groups supporting a radial spin texture. These two principles are used to screen materials databases for archetypes that go beyond the basic hedgehog radial spin texture. Among the selected materials we highlight the axion insulator candidate ${mathrm{Ta}}_{2}{mathrm{Se}}_{8}mathrm{I}$, the material proposed for dark matter detection ${mathrm{Ag}}_{3}mathrm{Au}{mathrm{Te}}_{2}$, and heazlewoodite ${mathrm{Ni}}_{3}{mathrm{S}}_{2}$, a conventional metal predicted to exhibit current-induced spin polarization. We point out that the symmetry analysis proposed in this Letter is more general and extends to studying other vector properties in momentum space.
