Summary: Exact propagating topological solitons are discovered in the easy-plane phase of ferromagnetic spin-1 Bose-Einstein condensates, appearing as kinks in the transverse magnetization. They can only propagate when a longitudinal magnetic field is present and have two types: a low energy branch with positive inertial mass and a higher energy branch with negative inertial mass. At the maximum speed, both types become identical.

Summary: In this study, we developed a spacetime-covariant Hamilton principle for the evolution of barotropic flows of a perfect fluid in the presence of an external axial-vector potential. It was found that the axial-current anomaly in quantum field theories with Dirac fermions can be interpreted as a kinematic property of classical hydrodynamics, and interesting effects can occur under the simultaneous actions of the electromagnetic field and the axial-vector potential. By using the Hamilton principle, we obtained the extended Euler equations accounting for the axial potential and derived anomalies in the divergence of the axial and vector currents. Our approach provides a hydrodynamic expression for the vector and axial currents and establishes a platform for studying flows with a chiral imbalance and their associated anomalies.

Summary: This study systematically examines the apparent diffusion of vortices in ultraquantum turbulence (UQT) in superfluid helium-4, showing that vortices exhibit universal anomalous diffusion at small times and transition to normal diffusion at large times. The findings suggest a generic scaling property of vortex velocity, with the simulation reproducing recent experimental observations and providing insights into turbulent transport and universal vortex dynamics in quantum fluids.

Summary: We studied anomalous chiral symmetry breaking in two-flavor QCD induced by gravitational and QCD-instantons within asymptotically safe gravity. We found that gravitational instantons in this scenario can generate contributions to the 't Hooft coupling, affecting anomalous U(1)(A) breaking at low energy scales.

Summary: Due to the Weyl anomaly, an axial vector field generates anomalous chiral currents in spacetime with boundaries, which are not invariant under gauge transformations. This paper investigates the anomalous chiral current in AdS/BCFT and finds that the minimal holographic model of the axial vector field fails to produce the expected chiral current. To address this issue, the authors propose the addition of a suitable boundary action. The shape dependence of holographic chiral current is obtained and shown to agree with the field-theoretical result.

Summary: In this study, the thermodynamics of superfluids is reexamined, leading to two key clarifications. Firstly, the density and pressure distribution is obtained for a given set of normal and superfluid velocities, showing that counter heat currents induce pressure depression and centripetal force. Secondly, it is demonstrated that the ideal two-fluid hydrodynamics can be understood as a collection of equilibrium conditions where entropy is maximized.

Summary: An intrinsic anomalous Hall effect is predicted to exist in a bosonic chiral superfluid in a 2D hexagonal boron nitride optical lattice. The high-frequency limit of the Hall conductivity is determined by finite loop current correlations, while the dc Hall conductivity traces back to the noninteracting band Berry curvature at the condensation momentum.

Summary: This study aims to investigate the diffusion of biological macromolecules in the cytoplasm, where there is a strict limitation on the accessible volume. By studying the thermal motion of spherical colloidal beads in giant unilamellar vesicles (GUVs), it is found that confinement and environmental viscoelasticity result in anomalous motion pathways for the encapsulated microbeads. This anomalous diffusion is dependent on the ratio between the particle and GUV volume, as well as the viscosity of the particle's liquid environment.

Summary: Theoretical results on the stability of half-quantum vortices (HQVs) in highly anisotropic Nafen aerogel-confined He-3 superfluid phases are reported. Two superfluid phases, a nematic superfluid and a chiral superfluid, are identified in He-3-Nafen, both hosting arrays of HQVs as stable states. These HQVs have distinct magnetic and topological signatures in the nematic and chiral phases of He-3-Nafen.

Summary: This article presents an analytical description of the local density of states (LDOS) for a microcavity with chiral exceptional points (EPs), demonstrating the unconventional behavior of quantum emitters (QEs) due to the non-Lorentzian response of EPs. The study reveals that the LDOS contribution from chiral EPs can interfere destructively or constructively with the linear Lorentzian profile, resulting in null Purcell enhancement or narrowed linewidth of Rabi splitting, respectively. The research also discovers that an open microcavity with chiral EPs supports atom-photon bound states for population trapping and decay suppression. The work showcases the unique cavity quantum electrodynamics enabled by chiral EPs and their potential applications in quantum optics devices.

Summary: In this paper, the Kinematical vortical effect (KVE) transport coefficients are studied using the Zubarev quantum-statistical density operator for the Rarita-Schwinger-Adler theory. The relationship with the gravitational anomaly is demonstrated and a prediction is made about the possible form of the transport coefficients for massless fields with arbitrary spin.

Summary: This study explores the effects of longitudinal expansion on the order parameter using the chiral fluid dynamics model, showing that oscillations gradually diminish and quark density moves towards forward rapidity with an increase in chemical potential. The dissipation present also plays a role in reducing the oscillations.

Summary: The text discusses the phenomenon of polarization rotation for light interacting with chiral materials and chiral fermions interacting with quantum electrodynamics plasma. It demonstrates that the rotation of polarization is perpendicular to both vorticity and fermion momentum, and it also exists in quantum chromodynamics plasma with vorticity. The effect could lead to generation of a vector current when the probe fermions contain momentum anisotropy.

Summary: The study develops covariant chiral kinetic theory with Landau level basis to investigate a magnetized plasma under perturbations of a transverse electric field and steady vorticity. By considering the vacuum shift, it is found that the resulting current and stress tensor in both cases match consistently with magnetohydrodynamics constitutive equations. The solution in the vorticity case contains shifts in temperature and chemical potential, as well as excitations of the lowest Landau level states, leading to new contributions to vector charge and axial current density.

Summary: In this study, we propose a method called dilepton helical rate, which counts the weighted difference between right-handed and left-handed lepton pairs. The weight is determined by the momentum difference of the lepton pairs projected onto an auxiliary vector. We derive the helical rate in a quark-gluon plasma and find that it is maximized when the auxiliary vector is parallel to the vorticity, resulting in a nearly spherical oblate ellipsoidal distribution. We suggest that this method can be used as a vortical-meter for quark-gluon plasma.

Summary: In this study, we investigate the fluctuation effect of the order parameter in a holographic superconductor model under the non-equilibrium system. Near the critical point, we derive the time-dependent Ginzburg-Landau effective action governing the dynamics of the fluctuating order parameter. Through a semi-analytical approach, we compute the time-dependent Ginzburg-Landau action up to quartic order of the fluctuating order parameter and first order in time derivative.
