Short--range impurity in the vicinity of a saddle point and the levitation of the 2D delocalized states in a magnetic field

, 1996
The effect of a short--range impurity on the transmission through a saddle--point potential for an electron, moving in a strong magnetic field, is studied.

Cooling the Motion of Diamond Nanocrystals in a Magneto-Gravitational Trap in High Vacuum

, 2016
Levitated diamond nanocrystals with nitrogen-vacancy (NV) centres in high vacuum have been proposed as a unique system for experiments in fundamental quantum mechanics, including the generation of large quantum superposition states and tests of quantum ...

Fault-Tolerant Control of Magnetic Levitation System Based on State Observer in High Speed Maglev Train

IEEE Access, 2019
In recent years, the high-speed rail train has achieved great progress, but the wheel–rail relationship and the catenary–pantograph relationship are the bottlenecks to further increase the speed.

Magnetic Levitation: An Academic Prototype

Applied Sciences
The vibrations that a shaft suffers when rotating affect both the friction and subsequent wear of the shaft. The main objective of this paper is to present an academic and experimental prototype that allows controlling the vibrations of a rotating shaft through magnetic levitation. The control was carried out with a microcontroller, electromagnets, and

Linear Model Predictive Control and Back-Propagation Controller for Single-Point Magnetic Levitation with Different Gap Levitation and Back-Propagation Offline Iteration

Actuators
Magnetic suspension balance systems (MSBSs) need to allow vehicle models to levitate stably in different attitudes, so it is difficult to ensure the stable performance of the system under different levitation gaps using a controller designed with single ...
