Heating and Cooling Curves02:44

Heating and Cooling Curves

23.2K
When a substance—isolated from its environment—is subjected to heat changes, corresponding changes in temperature and phase of the substance is observed; this is graphically represented by heating and cooling curves.
For instance, the addition of heat raises the temperature of a solid; the amount of heat absorbed depends on the heat capacity of the solid (q = mcsolidΔT). According to thermochemistry, the relation between the amount of heat absorbed or released by a substance,...

Atomic Nuclei: Nuclear Spin State Population Distribution

1.7K
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.

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...

Theory of Metallic Conduction01:17

Theory of Metallic Conduction

2.0K
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,...

Carrier Transport01:21

Carrier Transport

1.2K
The generation of electrical current in semiconductors is fundamentally driven by two mechanisms: drift and diffusion. These processes are essential for the functionality and performance of semiconductor-based devices.
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:

Area of Science:

  • Condensed Matter Physics
  • Quantum Materials Science

Background:

  • Quantum criticality describes systems with infinite interacting quantum degrees of freedom at zero temperature, exhibiting scale invariance.
  • Strongly correlated electron systems can undergo quantum phase transitions, leading to predicted quantum critical states with universal power-law behaviors.
  • While candidates exist in heavy-fermion systems and high-transition temperature (high-T(c)) copper oxides, the nature of these transitions remains debated.

Purpose of the Study:

  • To investigate the universal behaviors characteristic of the quantum critical region in materials.
  • To determine if high-T(c) superconductors exhibit unconventional quantum phase transitions.
  • To provide experimental evidence supporting or refuting the existence of quantum critical states in these materials.

Main Methods:

  • Experimental measurement of the phase angle in high-T(c) superconductors.
  • Analysis of the relationship between the measured phase angle and the exponent of optical conductivity.
  • Comparison of experimental results with theoretical predictions for quantum critical phenomena.

Main Results:

  • A universal behavior characteristic of the quantum critical region was observed.
  • The experimentally measured phase angle precisely matches the exponent of the optical conductivity.
  • This agreement provides strong evidence for a quantum phase transition in high-T(c) superconductors.

Conclusions:

  • The findings indicate the presence of a quantum critical region in high-T(c) superconductors.
  • The observed universal behavior suggests an unconventional type of quantum phase transition.
  • This research contributes to understanding the complex physics of strongly correlated electron systems and high-T(c) superconductivity.
