Kinetic Theory of an Ideal Gas

3.7K
A mole is defined as the amount of any substance that contains as many molecules as there are atoms in exactly 12 grams of carbon-12. An Italian scientist Amedeo Avogadro (1776–1856) formed the  hypothesis that equal volumes of gas at equal pressure and temperature contain equal numbers of molecules, independent of the type of gas. Later, the hypothesis was developed to form the SI unit for measuring the amount of any substance.
The number of molecules in one mole is called...

The Uncertainty Principle04:08

The Uncertainty Principle

25.4K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Newtonian Fluid: Problem Solving01:18

Newtonian Fluid: Problem Solving

414
Newtonian fluids exhibit a constant viscosity, meaning their shear stress and shear strain rate are directly proportional. This property ensures a predictable and stable response to applied forces, maintaining a linear relationship between force and flow. Examples include water, air, and light oils, consistently demonstrating this proportional behavior regardless of external conditions.
A velocity gradient forms within the fluid when a Newtonian fluid is placed between two parallel plates, with...

Area of Science:

  • Quantum hydrodynamics
  • Nonlinear optics
  • Fluid dynamics

Background:

  • Light propagation in nonlinear media exhibits quantum hydrodynamical behaviors distinct from classical fluids.
  • The piston problem, a gas dynamics paradigm, offers a framework to study these behaviors.
  • Accessing extreme quantum hydrodynamic regimes in light has been a significant challenge.

Purpose of the Study:

  • To investigate extreme quantum hydrodynamics in light using a generalized piston problem.
  • To explore optical rarefaction and shock wave pairs.
  • To identify the transition to a novel nonlinear wave flow regime.

Main Methods:

  • Utilizing a full-fiber setup to study light propagation in the temporal domain.
  • Implementing a generalized Riemann piston problem with abrupt changes in photon density.
  • Analyzing experimental observations of light wave dynamics.

Main Results:

  • Observed optical rarefaction and shock wave pairs corresponding to retracting and pushing pistons.
  • Discovered a transition to a unique flow regime above a critical piston velocity.
  • Demonstrated that light shocks interconnect smoothly via a large-contrast, periodic, fully nonlinear wave.

Conclusions:

  • The study successfully accessed an extreme quantum hydrodynamic regime for light.
  • The observed nonlinear wave flow represents a generic superfluid phenomenon, now demonstrated in light.
  • The fiber-based temporal domain setup is a versatile platform for studying quantum fluids of light.
