Magnetic Field due to Moving Charges01:23

Magnetic Field due to Moving Charges

12.2K
A stationary charge creates and interacts with the electric field, while a moving charge creates a magnetic field.
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...

Types Of Superconductors

1.8K
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...

Atomic Nuclei: Nuclear Relaxation Processes

1.4K
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis,  the precessing magnetic moments are randomly oriented around the z-axis.

Paramagnetism01:30

Paramagnetism

3.2K
Paramagnets are materials with unpaired electrons that possess a finite magnetic moment. In the absence of a magnetic field, these moments are randomly oriented, and thus the net moment is zero. Under an external field, a torque acting on the moments tends to align them along the field's direction. However, the random thermal motion of electrons produces a torque opposite to the external field and tries to disorient the moments. These two competing effects align only a few moments along the...

Diamagnetism01:26

Diamagnetism

3.3K
Materials consisting of paired electrons have zero net magnetic moments. However, when these materials are placed under an external magnetic field, the moments opposite to the field are induced. Such materials are called diamagnets. Diamagnetism is the response of the diamagnets when placed in an external magnetic field.
Diamagnetism was discovered by Anton Brugmans in 1778 when he observed that bismuth gets repelled by magnetic fields, thus theorizing that diamagnets get repelled by magnets....

Consider an infinitely long straight wire carrying a current I. The magnetic field at point P at a distance a from the origin can be calculated using the Biot-Savart law.

Summary

Pair-density-wave superconductivity lacks spin gaps and magnetic resonances, unlike d-wave superconductivity. This finding aligns with experiments on unconventional superconductors like La_{1.905}Ba_{0.095}CuO_{4}.

Area of Science:

  • Condensed Matter Physics
  • Materials Science

Background:

  • Pair-density-wave superconductivity is a novel electronic state proposed for unconventional superconductors.
  • Understanding this state is crucial for advancing the fundamental knowledge of superconductivity in correlated materials.

Purpose of the Study:

  • To investigate the dynamical magnetic susceptibility and spin-wave spectrum signatures of a pair-density-wave ordered state.
  • To differentiate pair-density-wave properties from those of d-wave superconductivity.

Main Methods:

  • Computation of dynamical magnetic susceptibility in a pair-density-wave state.
  • Analysis of the spin-wave spectrum, focusing on magnetic resonance features.

Main Results:

  • The pair-density-wave phase does not exhibit a spin gap.
  • No magnetic resonance peak was observed in the pair-density-wave state.
  • These results are consistent with neutron scattering data from underdoped La_{1.905}Ba_{0.095}CuO_{4}.

Conclusions:

  • The absence of a spin gap and magnetic resonance is a key characteristic distinguishing pair-density-wave superconductivity from d-wave superconductivity.
  • The findings support the existence of pair-density-wave order in certain unconventional superconductors.
