Significant phase deviation of magnetic quantum oscillations induced by magnetic impurities

NPG Asia Materials
Magnetic quantum oscillations, such as Shubnikov-de Haas oscillations or de Haas-van Alphen oscillations, are widely used tools for fermiology. Notably, the phase of magnetic quantum oscillations could inform about the symmetry or topology of materials ...

Inferring physical parameters of solar filaments from simultaneous longitudinal and transverse oscillations

Astronomy & Astrophysics
Context. Different modes of oscillations are frequently observed in solar prominences, and prominence seismology helps estimate important physical parameters such as the magnetic field strength.

The Effect of Interface Tension on Forced Oscillations of Elongated Microdroplet Aggregates in Magnetic Fluids [PDF]

Журнал нано- та електронної фізики, 2014
Changes in the shape of microdroplet aggregates exposed to an alternating magnetic field with frequency from 0.01 to 1 Hz are investigated both experimentally and using a computer simulation.

Supercurrent interference in HgTe-wire Josephson junctions

Physical Review Research, 2023
Wires made of topological insulators (TI) are a promising platform for searching for Majorana bound states. These states can be probed by analyzing the fractional ac Josephson effect in Josephson junctions with the TI wire as a weak link.

Electrocapillary Modulated Interfacial Tension Amplifies Liquid Metal Transduction

Advanced Functional Materials, EarlyView.
This study presented an electrocapillary‐enhanced magnetohydrodynamic pumping strategy that harnesses the Lorentz force and interfacial tension modulation of liquid metal droplets to achieve amplified fluidic power. The system enabled low‐voltage, self‐oscillating fluidic transduction with enhanced pressure and flow generation, supporting compact ...

Determination of magnetoelastic oscillations in ferrite plate with different values of anisotropy constant

EPJ Web of Conferences, 2018
The maximum amplitudes of magnetic and elastic oscillations are calculated at various material parameters and parameters of external fields. Normally and tangentially magnetized anisotropic magnetic plates were considered.

Time‐Resolved Magnetization Switching Dynamics Driven by Orbital Torques

Advanced Functional Materials, EarlyView.
Du et al. reveal nanosecond magnetization switching driven by orbital currents using time‐resolved Hall detection. The measurements separate domain nucleation from domain wall propagation and show that Joule heating strongly assists switching by lowering energy barriers.

Magnetic clock for a harmonic oscillator

Physical Review A
We present an implementation of a recently proposed procedure for defining time, based on the description of the evolving system and its clock as non-interacting, entangled systems, according to the Page and Wootters approach. We study how the quantum dynamics transforms into a classical-like behaviour when conditions related with macroscopicity are ...

Torsional oscillations of magnetized relativistic stars [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
Strong magnetic fields in relativistic stars can be a cause of crust fracturing, resulting in the excitation of global torsional oscillations. Such oscillations could become observable in gravitational waves or in high-energy radiation, thus becoming a tool for probing the equation of state of relativistic stars.

Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective

Advanced Functional Materials, EarlyView.
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in
