The Hall Effect01:30

The Hall Effect

3.3K
Edwin H. Hall, in the year 1879, devised an experiment that could be used to identify the polarity of the predominant charge carriers in a conducting material. From a historical perspective, this experiment was the first to demonstrate that the charge carriers in most metals are negative.

Theory of Metallic Conduction01:17

Theory of Metallic Conduction

1.6K
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,...

Atomic Spectroscopy: Effects of Temperature

715
Atomization, converting samples into gas-phase atoms and ions, is essential for atomic spectroscopy. The flame temperature required for atomization affects the efficiency of the atomic spectroscopic methods by increasing the atomization efficiency and the relative population of the excited and ground states.
At thermal equilibrium, the relative populations of excited and ground state atoms can be estimated using the Maxwell–Boltzmann distribution. For example, an increase in temperature...

Quantifying Heat

60.4K
Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a higher temperature. When the...

Conduction, Convection and Radiation: Problem Solving01:20

Conduction, Convection and Radiation: Problem Solving

2.0K
There are three methods by which heat transfer can take place: conduction, convection, and radiation. Each method has unique and interesting characteristics, but all three have two things in common: they transfer heat solely because of a temperature difference; and the greater the temperature difference, the faster the heat transfer.
In order to solve a problem related to heat transfer, first of all, the situation needs to be examined to determine the type of heat transfer involved. This could...

Heat Capacities of an Ideal Gas III01:25

Heat Capacities of an Ideal Gas III

2.6K
The number of independent ways a gas molecule can move along straight line, rotate, and vibrate is called its degrees of freedom. Supposing d represents the number of degrees of freedom of an ideal gas, the molar heat capacity at constant volume of an ideal gas in terms of d is

Summary

Nontopological "thermal metal" phases can mimic the quantized thermal Hall response of non-Abelian quasiparticles. This effect, driven by disorder, improves with temperature, potentially impacting experimental interpretations.

Area of Science:

  • Condensed Matter Physics
  • Quantum Materials
  • Topological Phases

Background:

  • The search for non-Abelian quasiparticles is a significant area of research, yet direct experimental probes remain scarce.
  • A key signature of non-Abelian phases is a quantized thermal Hall conductance, observed recently in quantum-Hall systems and magnetic insulators.

Purpose of the Study:

  • To investigate whether nontopological phases can exhibit signatures resembling non-Abelian quasiparticles.
  • To analyze the role of quenched disorder in creating such misleading thermal Hall responses.

Main Methods:

  • Theoretical analysis of thermal Hall conductance in disordered systems.
  • Numerical simulations to provide evidence for the proposed mechanism.

Main Results:

  • Nontopological "thermal metal" phases, arising from quenched disorder, can closely approximate the quantized thermal Hall response characteristic of non-Abelian phases.
  • The observed quantization in these disordered systems paradoxically improves with increasing temperature, unlike in gapped systems.

Conclusions:

  • Disordered "thermal metal" phases present a potential experimental challenge, possibly being misinterpreted as non-Abelian quasiparticles.
  • The temperature dependence of the thermal Hall response in disordered systems offers a distinguishing characteristic from true non-Abelian phases.
