ACCRETION ONTO A MAGNETIC DIPOLE: RESULTS OF 2D NUMERICAL SIMULATIONS

Odessa Astronomical Publications, 2017
Different regimes of accretion to a star with a dipole magnetic field were investigated using 2D numerical axisymmetric resistive MHD simulations. Numerical technique was improved over our recently published results (Toropin et al., 1999, referred as T99

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

Ligand Engineering for Precise Control of Ultrathin CsPbI3 Nanoplatelet Superlattices for Efficient Light‐Emitting Diodes

Advanced Materials, EarlyView.
In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.

Decoherence of quantum local fisher and uncertainty information in two-qubit NV centers

Scientific Reports
This study aims to investigate the decoherence of the quantum correlation dynamics of two qubit nitrogen-vacancy (NV) centres through local quantum uncertainty (LQU), local quantum Fisher information (LQFI), and concurrence.

Enhanced terahertz magnetic dipole response by subwavelength fiber

APL Photonics, 2018
Dielectric sub-wavelength particles have opened up a new platform for realization of magnetic light. Recently, we have demonstrated that a dipole emitter by a sub-wavelength fiber leads to an enhanced magnetic response.

Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids

Advanced Materials, EarlyView.
Strong dipole–dipole interactions give rise to an emergent polar smectic phase with spontaneous chiral symmetry breaking. This resulting polar heliconical smectic superstructure enables novel functionalities in polar fluids, such as color modulation driven by electric field strength and frequency, as well as second‐harmonic generation amplification ...

Field‐Programmable Mobile Magneto‐Photonic Metaparticles for Active Light Manipulation and Steering

Advanced Materials, EarlyView.
We report magneto‐photonic metaparticles that integrate magnetic actuation with nanoimprinted metagratings, enabling mobile and programmable beam steering in aqueous environments. This platform achieves real time, directional light control beyond static or line‐of‐sight systems, while remaining compatible with scalable fabrication, providing a ...

Circular motion and collisions of particles with magnetic dipole moment and electric charge in dipolar magnetosphere around Schwarzschild black holes

European Physical Journal C: Particles and Fields
No-hair theorem indicates that black holes cannot have their own magnetic dipole moment. They can be weakly magnetized in binary systems with a neutron star companion and an accretion disc of charged particles.

Decoupling Activation and Preservation: Architectural Design Principles of Organic Frameworks for Selective Photocatalytic Methane Oxidation

Advanced Materials, EarlyView.
Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...
