Types Of Superconductors

Types Of Superconductors

A superconductor is a substance that offers zero resistance to the electric current when it drops below a critical temperature. Zero resistance is not the only interesting phenomenon as materials reach their transition temperatures. A second effect is the exclusion of magnetic fields. This is known as the Meissner effect. A light, permanent magnet placed over a superconducting sample will levitate in a stable position above the superconductor. High-speed trains that levitate on strong...

Superconductor

A substance that reaches superconductivity, a state in which magnetic fields cannot penetrate, and there is no electrical resistance, is referred to as a superconductor. In 1911, Heike Kamerlingh Onnes of Leiden University, a Dutch physicist, observed a relation between the temperature and the resistance of the element mercury. The mercury sample was then cooled in liquid helium to study the linear dependence of resistance on temperature. It was observed that, as the temperature decreased, the...

Area of Science:

Condensed Matter Physics
Metamaterials
Terahertz Photonics

Background:

Electromagnetically induced transparency (EIT) is a quantum interference phenomenon enabling light propagation in normally opaque media.
Metamaterials offer novel ways to control electromagnetic waves, including slow-light effects.
Superconducting materials exhibit unique electromagnetic properties, especially at cryogenic temperatures.

Purpose of the Study:

To experimentally realize a tunable EIT-like response in a bright-bright mode resonator system.
To investigate the slow-light effect and its dependence on temperature in a novel metamaterial structure.
To elucidate the underlying physical mechanisms governing the observed phenomena.

Main Methods:

Fabrication of a composite metamaterial using niobium nitride (NbN) and gold films.
Experimental measurement of transmission spectra and group delay to observe EIT-like response and slow-light.
Application of a hybrid coupling model to fit experimental data and extract resonator parameters.

Main Results:

Achieved a tunable EIT-like response in the bright-bright mode resonators.
Observed a significant slow-light effect with a maximum group index of 100.
Demonstrated temperature-dependent transmittance and slow-light due to variations in NbN film's ohmic loss.

Conclusions:

The study provides experimental validation of EIT-like phenomena in metamaterial analogs.
The hybrid coupling model accurately describes the experimental transmission spectra and sub-resonator characteristics.
The findings offer a pathway for developing tunable terahertz devices like slow-light systems, filters, and modulators.
