We found four behaviors of driven superconducting vortices interacting with disorder, distinguished by memory effects. Fragile and jammed states show memory, while elastic and pinning-dominated regimes do not.
Area of Science:
- Condensed Matter Physics
- Superconductivity
Background:
- Driven superconducting vortices are crucial in understanding.
- Quenched disorder influences vortex dynamics significantly.
Purpose of the Study:
- To investigate the behavior of driven superconducting vortices under quenched disorder.
- To identify distinct phases based on memory effects.
Main Methods:
- Applying a sequence of perpendicular drive pulses.
- Analyzing spatial vortex configurations.
- Varying disorder strength.
Main Results:
- Identified four distinct behaviors: fragile, jammed, elastic, and pinning-dominated.
- Fragile and jammed states exhibit memory effects.
- Memory effects correlate with coexisting elastic and pinned vortex components.
Conclusions:
- The proposed driving protocol can distinguish between vortex phases.
- Findings offer insights into driven interacting particle systems with disorder.

Magnetic Field due to Moving Charges
Consider a point charge moving with a constant velocity. Like the electric field, the magnetic field at any point is directly proportional to the magnitude of the charge and inversely proportional to the square of the distance between the source point and the field point. However, unlike the electric field, the magnetic field is always perpendicular to the plane containing the line...
