Explanation of phenomena

BKL theory

Energy of electron pairs:

Δ = 3.52kBTc

where Tc - critical temperature, kB - Boltzmann constant

Meissner effect

Magnetic field expulsion:

B = μ₀(H + M) = 0

M = -H - full diamagnetization

Quantum conductivity

Superconductor conductivity:

G = (2e²/h)∑Tᵢ

G₀ = 2e²/h ≈ 77.5 µS - conductance quantum

Critical magnetic field

Negative conductivity:

Hc(T) = Hc(0)[1-(T/Tc)²]

Hc(0) - critical field at T = 0

Common questions

What is superconductivity?

Supercapacity is a phenomenon of zero electrical resistance and complete expulsion of magnetic fields at low temperatures.

WHAT IS THE MEISSNER EFFECT?

The Meissner effect involves complete expulsion of magnetic fields from the volume of a superconductor, leading to levitation of magnets.

What is a quantum field?

Quantum fluid (for example, rare helium) shows quantum properties on a macroscale, including superfluidity.

Why is critical temperature important?

CRITICAL temperature defines the boundary below which material becomes a conductor. Higher CRITICAL temperature allows using cheaper cooling systems.
