Superconductor

1.9K
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 Superconductors

1.7K
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...

Chirality

31.1K
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Electric Field Inside a Conductor

7.6K
When a conductor is placed in an external electric field, the free charges in the conductor redistribute and very quickly reach electrostatic equilibrium. The resulting charge distribution and its electric field have many interesting properties, which can be investigated with the help of Gauss's law.
Suppose a piece of metal is placed near a positive charge. The free electrons in the metal are attracted to the external positive charge and migrate freely toward that region. This region then...

Magnetic Field Due To A Thin Straight Wire

6.4K
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.

Ferromagnetism01:31

Ferromagnetism

3.3K
Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...

Area of Science:

  • Condensed Matter Physics
  • Materials Science
  • Nanotechnology

Background:

  • Chirality in materials impacts optical, magnetic, and electric properties, leading to phenomena like circular dichroism and nonreciprocal transport.
  • The effect of chirality on superconducting transport remained largely unexplored.

Purpose of the Study:

  • To investigate the influence of chirality on superconducting transport.
  • To demonstrate unambiguous evidence of superconductivity reflecting chiral structure.

Main Methods:

  • Utilizing ionic gating to realize superconductivity in individual chiral nanotubes of tungsten disulfide.
  • Analyzing the nonreciprocity of supercurrent flow and quantum Little-Parks oscillations.

Main Results:

  • Observed nonreciprocity in superconductivity, where forward and backward supercurrent flows are not equivalent due to broken inversion symmetry.
  • Significantly enhanced nonreciprocal signal in the superconducting state.
  • Observed unprecedented quantum Little-Parks oscillations linked to supercurrent interference along the nanotube circumference.

Conclusions:

  • Demonstrated chiral superconductivity in tungsten disulfide nanotubes, a novel phenomenon.
  • The findings suggest nonreciprocity is a key feature for superconductors with chiral or noncentrosymmetric structures.
  • Opens new avenues for designing advanced superconducting materials.
