Vortices in Tunable Dipolar Bose-Einstein condensates with Attractive Interactions​

S. Sabari, R. Sasireka, R. Radha, A. Uthayakumar, L. Tomio

We investigate the formation of vortices in quasi-two-dimensional dipolar Bose-Einstein Condensates (BECs) through the interplay between two-body contact and long-ranged dipole-dipole interactions (DDIs), as both interactions can be tuned from repulsive to attractive. By solving the associated Gross-Pitaevskii equation for a rotating system, our initial approach concentrates on stabilizing a collapsing condensate with attractive s-wave two-body interactions by employing sufficiently large repulsive DDIs. Subsequently, the same procedure was applied after reversing the signs of both interactions to evaluate the sensitivity of vortex formation to such an interchange of interactions. As a reference to guide our investigation, valid for generic dipolar atomic species, we have assumed a condensate with the strong dipolar dysprosium isotope, 164Dy. The correlation of the results with other dipolar BEC systems was exemplified by considering rotating BECs with two other isotopes, namely 168Er and 52Cr. For a purely dipolar condensate (with zero contact interactions) under fixed rotation, we demonstrate how the number of visible vortices increases as the DDI becomes more repulsive, accomplished by tuning the orientation of the dipoles through a characteristic angle parameter.

(Changes of the rotational period observed in various magnetized accreting sources are generally attributed to the interaction between the in-falling plasma and the large-scale magnetic field of the accretor)

My Opinion.
Dipolar jets expel matter, some at the speed of light, which, in my opinion, is fully expelled from the CORE and not by infalling matter. A prime example of nucleosynthesis.

Context. Changes of the rotational period observed in various magnetized accreting sources are generally attributed to the interaction between the in-falling plasma and the large-scale magnetic field of the accretor. A number of models have been proposed to link these changes to the mass accretion rate, based on different assumptions on the relevant physical processes and system parameters. For X-ray binaries with neutron stars, with the help of precise measurements of the spin periods provided by current instrumentation, these models render a way to infer such parameters as the strength of the dipolar field and a distance to the system. Often, the obtained magnetic field strength values contradict those from other methods used to obtain magnetic field estimates.
Aims. We want to compare the results of several of the proposed accretion models. To this end an example application of these models to data is performed.
Methods. We reformulate the set of disk accretion torque models in a way that their parametrization are directly comparable. The application of the reformulated models is discussed and demonstrated using Fermi/GBM and Swift/BAT monitoring data covering several X-ray outbursts of the accreting pulsar 4U 0115+63.
Results. We find that most of the models under consideration are able to describe the observations to a high degree of accuracy and with little indication for one model being preferred over the others. Yet, derived parameters from those models show a large spread. Specifically the magnetic field strength ranges over one order of magnitude for the different models. This indicates that the results are heavily influenced by systematic uncertainties.

Particle acceleration by magnetic reconnection in geospace​

Mitsuo Oka, Joachim Birn, Jan Egedal, Fan Guo, Robert E. Ergun, Drew L. Turner, Yuri Khotyaintsev, Kyoung-Joo Hwang, Ian J. Cohen, James F. Drake

Particles are accelerated to very high, non-thermal energies during explosive energy-release phenomena in space, solar, and astrophysical plasma environments. While it has been established that magnetic reconnection plays an important role in the dynamics of Earth's magnetosphere, it remains unclear how magnetic reconnection can further explain particle acceleration to non-thermal energies. Here we review recent progress in our understanding of particle acceleration by magnetic reconnection in Earth's magnetosphere. With improved resolutions, recent spacecraft missions have enabled detailed studies of particle acceleration at various structures such as the diffusion region, separatrix, jets, magnetic islands (flux ropes), and dipolarization front. With the guiding-center approximation of particle motion, many studies have discussed the relative importance of the parallel electric field as well as the Fermi and betatron effects. However, in order to fully understand the particle acceleration mechanism and further compare with particle acceleration in solar and astrophysical plasma environments, there is a need for further investigation of, for example, energy partition and the precise role of turbulence.

Observation of the Einstein-de Haas Effect in a Bose-Einstein condensate​

Hiroki Matsui, Yuki Miyazawa, Ryoto Goto, Chihiro Nakano, Yuki Kawaguchi, Masahito Ueda, Mikio Kozuma

The Einstein-de Haas effect is a phenomenon in which angular momentum is transferred from microscopic spins to mechanical rotation of a rigid body. Here, we report the first observation of the Einstein-de Haas effect in a spinor-dipolar Bose-Einstein condensate where quantized vortices emerge in depolarized spinor components through coherent angular-momentum transfer from microscopic atomic spins to macroscopic quantized circulation. Experimental results clearly show that the spherical symmetry of the condensate is dynamically broken into the axisymmetry by an intrinsic magnetic dipole-dipole interaction.

Phase alignment in a lattice of exciton-polaritonic Bose-Einstein condensates​

N.V. Kuznetsova, D.V. Makarov, N.A. Asriyan, A.A. Elistratov

Dynamics of exciton-polariton Bose-Einstein condensate is examined by means of the stochastic Gross-Pitaevskii equation including non-Markovian coupling to the excitonic reservoir. Attention is concentrated on properties of the condensate lattice created by laser beams providing incoherent pumping of the reservoir. It is shown that phase ordering of the lattice depends on temperature. The crossover between the in-phase (``ferromagnetic'') and the checkboard (``antiferromagnetic'') orders is accompanied by variation of the steady-state condensate density. Also it is shown that the condensate lattices can retain ordered pattern for temperatures which are much higher than the critical temperature of a single spot, probably due to suppression of the modulational instability.

Chiral supersymmetry dipolar electromagnetic vector fields can attract matter in contraction and expansion via jets.
For example, some contraction to the core of M87 covers thousands of light years.
Jets have a width of over a light month, and jets expand over 100,000 light years.

Magnetar field dynamics shaped by chiral anomalies and helicity​

Clara Dehman, José A. Pons

The chiral magnetic effect (CME), a macroscopic manifestation of the quantum chiral anomaly, induces currents along magnetic field lines, facilitating mutual conversion between chiral asymmetry and magnetic helicity. Although the finite electron mass suppresses chiral asymmetry through spin-flip processes, we demonstrate that the CME remains effective and plays a significant role in the magnetic field evolution of magnetars. The magnetic helicity acts as a persistent internal source of chiral asymmetry, which mediates the redistribution of magnetic energy across spatial scales, without requiring an external energy source. Focusing on the neutron star crust, we show that this mechanism reshapes the magnetic field configuration inherited at birth and, within a hundred years, amplifies both toroidal and poloidal large-scale dipolar components (relevant for spin-down) up to

G at the expense of small-scale structures. Our results offer a microphysical mechanism, alternative to traditional hydrodynamic dynamo models, establishing a new framework for understanding magnetar field dynamics.

Magnetic field morphologies in convective zones influenced by a turbulent surface layer​

Anna Guseva, Ludovic Petitdemange, Charly Pinçon

Spectropolarimetric observations show that many low-mass stars possess large-scale poloidal magnetic fields with considerable dipole component, which in some cases exhibit temporal dynamics - cycles or reversals. Although it is widely accepted that their magnetic fields are generated by the dynamo process, it is hard to reproduce coherent oscillations of large-scale magnetic fields with a dipolar symmetry as observed for the Sun when turbulent and compressible regimes are explored. Most previous 3D numerical studies partially avoided this problem by considering a numerical domain with low density stratification, which may correspond to neglecting surface effects where density drops considerably. To address this question, we perform direct numerical simulations of convective dynamos in extreme parameter regimes of both strong turbulence and strong density stratification, using software MagIC. Our simulations exhibit rotationally-influenced large-scale convective motions surrounded by a turbulent compressible surface layer. We find complex time variations of the magnetic field in flow regimes of predominantly dipolar configuration with respect to the few large-scale harmonics. In such regimes, turbulent surface layer induces global magnetic pumping mechanism, transporting magnetic energy into the deep interiors of our dynamo model. Dipole magnetic fields are found in regimes of transition between solar- and anti-solar differential rotation, and interact dynamically with it. The spatial distribution and temporal behavior of the large-scale fields is consistent with observations of low-mass stars, which suggest magnetic pumping could promote time-dependent magnetic fields with a dipolar symmetry as observed for the Sun and other solar-like stars. Our results suggest a parameter path in which dynamo models with a complex multiscale dynamics should be explored.

VAST-MeMeS: Characterising non-thermal radio emission from magnetic massive stars using the Australian SKA Pathfinder​

Barnali Das, Laura N. Driessen, Matt E. Shultz, Joshua Pritchard, Kovi Rose, Yuanming Wang, Yu Wing Joshua Lee, Gregory Sivakoff, Andrew Zic, Tara Murphy

Magnetic massive stars are stars of spectral types O, B and A that harbour

kG strength (mostly dipolar) surface magnetic fields. Their non-thermal radio emission has been demonstrated to be an important magnetospheric probe, provided the emission is fully characterised. A necessary step for that is to build a statistically significant sample of radio-bright magnetic massive stars. In this paper, we present the `VAST project to study Magnetic Massive Stars' or VAST-MeMeS that aims to achieve that by taking advantage of survey data acquired with the Australian SKA Pathfinder telescope. VAST-MeMeS is defined under the `VAriable and Slow Transient' (VAST) survey, although it also uses data from other ASKAP surveys. We found radio detections from 48 magnetic massive stars, out of which, 14 do not have any prior radio detections. We also identified 9 `Main-sequence Radio Pulse Emitter' candidates based on variability and circular polarisation of flux densities. The expanded sample suggests a lower efficiency in the radio production than that reported in earlier work. In addition to significantly expanding the sample of radio-bright magnetic massive stars, the addition of flux density measurements at

GHz revealed that the spectra of incoherent radio emission can extend to much lower frequencies than that assumed in the past. In the future, radio observations spanning wide frequency and rotational phase ranges should be conducted so as to reduce the uncertainties in the incoherent radio luminosities. The results from these campaigns, supplemented with precise estimations of stellar parameters, will allow us to fully understand particle acceleration and non-thermal radio production in large-scale stellar magnetospheres.
