Quantifying Heat

63.1K
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...

Heat Capacities of an Ideal Gas II

For a system that undergoes a thermodynamic process at a constant volume condition, the heat absorbed is used only to increase the system's internal energy and not for doing any kind of work. While for a system undergoing a thermodynamic process under a constant pressure condition, the amount of heat absorbed is used not only for increasing the internal energy (as a function of temperature) but also for doing some work. The molar heat capacity is the amount of heat required to increase the...

Heat Capacities of an Ideal Gas I

Heat capacity is the ratio of heat absorbed by the substance corresponding to its temperature change. It is also called thermal capacity and the SI unit of heat capacity is J/K. Whereas, specific heat capacity is defined as the amount of heat necessary to change the temperature of 1 kg of a substance by 1 K and is also called massic heat capacity. Its SI unit is J/kg⋅K.
Molar heat capacity quantifies the ratio of the amount of heat added (or removed) to increase (or decrease) the...

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

Mechanisms of Heat Transfer

1.9K
Heat transfer between the human body and its environment occurs through four main mechanisms: conduction, convection, radiation, and evaporation.
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant...

Mechanisms of Heat Transfer I

6.7K
Just as interesting as the effects of heat transfer on a system are the methods by which the heat transfer occur. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, such as through a cooking pan, or slowly, such as through the walls of a picnic ice box. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet, every heat transfer takes place by only three methods: conduction, convection, and radiation.

Area of Science:

  • Condensed Matter Physics
  • Quantum Physics

Background:

  • The quantum of thermal conductance is a fundamental constant for ballistic channels.
  • Experimental verification of thermal conductance quantization has been challenging, especially in strongly interacting systems.
  • The fractional quantum Hall effect involves electron fractionalization into anyons, with potential Majorana fermion emergence.

Purpose of the Study:

  • To experimentally demonstrate the quantization of thermal conductance in strongly interacting systems, specifically in fractional quantum Hall states.
  • To investigate thermal conductance in both particle-like and hole-like states within a two-dimensional electron gas.
  • To explore how topological properties and anyonic heat flow in these systems can be accessed via thermal conductance measurements.

Main Methods:

  • Measurements of thermal conductance were performed on a high-mobility two-dimensional electron gas in GaAs-AlGaAs heterostructures.
  • The study focused on particle-like (Laughlin-Jain series) and hole-like states within the fractional quantum Hall regime.
  • Analysis involved characterizing the contribution of chiral edge modes (charged and neutral) to thermal transport.

Main Results:

  • The quantization of thermal conductance was successfully established for both particle-like and hole-like fractional quantum Hall states.
  • Results confirm the universality of thermal conductance quantization across different types of fractionalized electronic systems.
  • Measurements revealed that thermal conductance in hole-like states is determined by the net chirality of all edge modes.

Conclusions:

  • The experimental findings validate the theoretical prediction of quantized thermal conductance in strongly correlated electronic systems.
  • Measurements of anyonic heat flow offer unique insights into topological properties not accessible through electrical conductance alone.
  • This work establishes a new avenue for probing exotic quantum phenomena in condensed matter systems.
