Levitation of quantum Hall critical states in a lattice model with spatially correlated disorder

open access: yes, 2003
The fate of the current carrying states of a quantum Hall system is considered in the situation when the disorder strength is increased and the transition from the quantum Hall liquid to the Hall insulator takes place.

Frequency Analysis of a Superconducting Magnetic Bearing System in Ring Spinning Using an Eddy Current Damper

open access: yesPAMM, Volume 26, Issue 1, March 2026.
ABSTRACT The conventional ring‐spinning process has been used for over a century, being one of the most used processes in the textile industry. However, this process has some disadvantages at high spindle speeds, such as friction in the traveler/ring components that generates heat, resulting in yarn breakages or lower‐quality production.

Dusty plasma cavities: probe-induced and natural

open access: yes, 2014
A comprehensive exploration of regional dust evacuation in complex plasma crystals is presented. Voids created in 3D crystals on the International Space Station have provided a rich foundation for experiments, but cavities in dust crystals formed in ...

Mathematical Modeling of Measured Recalescence Velocities

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 2, Page 977-988, 30 January 2026.
ABSTRACT A moving‐boundary problem of synchronous directional and volumetric solidification in undercooled liquid drops is formulated and solved. Directional solidification is caused by the temperature gradient along the spatial direction, whereas volumetric growth of new phase elements is caused by the melt undercooling ahead of the phase transition ...

High‐Entropy Alloy Design Toward Cobalt Substitution for High Hardness and Low Wear Rate Using X–Cr–Fe–Mn–Ni System

open access: yesAdvanced Engineering Materials, Volume 28, Issue 2, January 21, 2026.
This study explores the replacement of cobalt using the high‐entropy alloy design strategy for wear‐resistant components operating at high temperatures. Starting from the Cantor alloy, cobalt is substituted with Cu, Al, V, or Mo. Metallurgical and tribological analyses reveal that aluminum, vanadium, and molybdenum effectively strengthen the developed ...

Measuring the interaction force between a high temperature superconductor and a permanent magnet

open access: yes, 1999
Repulsive and attractive forces are both possible between a superconducting sample and a permanent magnet, and they can give place to magnetic levitation or free-suspension phenomena, respectively.

Damping and non-linearity of a levitating magnet in rotation above a superconductor

open access: yesNew Journal of Physics, 2014
We study the dissipation of moving magnets in levitation above a superconductor. The rotation motion is analyzed using optical tracking techniques. It displays a remarkable regularity together with long damping time up to several hours.
