Superconductor01:24

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...
Types Of Superconductors01:28

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...
Theory of Metallic Conduction01:17

Theory of Metallic Conduction

The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...
Density00:56

Density

Density is an important characteristic of substances, crucial in determining whether an object sinks or floats in a fluid. Its SI unit is kg/m3, and its cgs unit is g/cm3. The density of an object helps in identifying its composition, and also reveals information about the phase of the matter and its substructure. The densities of liquids and solids are roughly comparable, consistent with the fact that their atoms are in close contact. However, gases have much lower densities than liquids and...
Boundary Conditions for Current Density01:25

Boundary Conditions for Current Density

Current density becomes discontinuous across an interface of materials with different electrical conductivities. The normal component of the current density is continuous across the boundary.
Second Uniqueness Theorem01:16

Second Uniqueness Theorem

Consider a region consisting of several individual conductors with a definite charge density in the region between these conductors. The second uniqueness theorem states that if the total charge on each conductor and the charge density in the in-between region are known, then the electric field can be uniquely determined.
In contrast, consider that the electric field is non-unique and apply Gauss's law in divergence form in the region between the conductors and the integral form to the surface...

Summary

Superfluid density in quantum critical superconductors shows an anomalous 3/2 power-law temperature dependence, deviating from the expected T-linear behavior. This finding suggests strong quantum fluctuations impact superconducting properties near quantum critical points.

Area of Science:

  • Condensed Matter Physics
  • Quantum Materials
  • Superconductivity

Background:

  • Quantum critical points (QCPs) arise when a second-order magnetic phase transition is tuned to zero temperature.
  • Near QCPs, quantum fluctuations are enhanced, potentially leading to unconventional superconductivity.
  • Normal-state properties of these quantum critical superconductors often display non-Fermi liquid behavior and strong electron correlations.

Purpose of the Study:

  • To investigate the effect of strong critical fluctuations on the superconducting condensate below the critical temperature (Tc).
  • To explore the temperature dependence of the superfluid density in various unconventional superconductors near antiferromagnetic QCPs.

Main Methods:

  • Measurements of the magnetic penetration depth.
  • Study of heavy-fermion, iron-pnictide, and organic superconductors located near antiferromagnetic quantum critical points.

Main Results:

  • A universal anomalous 3/2 power-law temperature dependence of superfluid density was observed in nodal superconductors near QCPs.
  • This behavior deviates significantly from the expected T-linear dependence.

Conclusions:

  • The observed noninteger power law suggests a strong renormalization of the effective Fermi velocity near the nodes of the superconducting energy gap.
  • This phenomenon, termed "nodal criticality," likely impacts the low-energy properties of quantum critical superconductors.
