Superconductor

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 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...

Electric Field at the Surface of a Conductor

Electric Field at the Surface of a Conductor

Consider a conductor in electrostatic equilibrium. The net electric field inside a conductor vanishes, and extra charges on the conductor reside on its outer surface, regardless of where they originate.
In the 19th century, Michael Faraday conducted the famous ice pail experiment to prove that the charges always reside on the surface of a conductor. The experimental set-up consists of a conducting uncharged container mounted on an insulating stand. The outer surface of the container is...

Equipotential Surfaces and Conductors

Equipotential Surfaces and Conductors

For a conductor in which all charges are at rest, the conductor's surface is equipotential. The electric field is always perpendicular to equipotential surfaces. Therefore, in a conductor with static charges, the electric field just outside the conductor is always perpendicular to the conductor's surface. Any tangential component of the electric field will cause charges to move inside the conductor, which will violate the electrostatic nature of the system. In an electrostatic situation, if a...

Ferromagnetism

Ferromagnetism

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...

Background:

High-temperature superconductors (cuprates) exhibit complex electronic behavior.
Underdoped cuprates show quantum oscillations and negative Hall coefficients, indicating an electron pocket in their Fermi surface.
This suggests a Fermi surface reconstruction from the overdoped regime.

Purpose of the Study:

To investigate the role of stripe order in Fermi surface reconstruction in hole-doped cuprates.
To identify the critical doping concentration for this reconstruction.
To analyze the transport properties at this critical doping.

Main Methods:

Analysis of quantum oscillation data.
Examination of Hall coefficient measurements.
Theoretical consideration of stripe order (charge/spin modulation).
Identification of critical doping levels.
Analysis of temperature dependence of transport coefficients.

Main Results:

Quantum oscillations and negative Hall coefficient reveal an electron pocket in underdoped cuprates.
Stripe order is identified as the cause of Fermi surface reconstruction.
The critical doping for reconstruction is identified.
Transport coefficients at critical doping resemble those of metals at a quantum critical point.
The pseudogap phase may be a precursor to stripe order.

Conclusions:

Stripe order drives Fermi surface reconstruction in hole-doped cuprates.
This reconstruction is linked to quantum critical behavior.
The pseudogap phase is potentially related to fluctuating stripe order.
