First Law: Particles in One-dimensional Equilibrium01:10

First Law: Particles in One-dimensional Equilibrium

8.6K
Newton's first law of motion states that a body at rest remains at rest, or if in motion, remains in motion at constant velocity, unless acted on by a net external force. It also states that there must be a cause for any change in velocity (a change in either magnitude or direction) to occur. This cause is a net external force. For example, consider what happens to an object sliding along a rough horizontal surface. The object quickly grinds to a halt, due to the net force of friction. If...

First Law: Particles in Two-dimensional Equilibrium

17.0K
Recall that a particle in equilibrium is one for which the external forces are balanced. Static equilibrium involves objects at rest, and dynamic equilibrium involves objects in motion without acceleration; but it is important to remember that these conditions are relative. For instance, an object may be at rest when viewed from one frame of reference, but that same object would appear to be in motion when viewed by someone moving at a constant velocity.

The de Broglie Wavelength

34.8K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Steady, Laminar Flow Between Parallel Plates01:17

Steady, Laminar Flow Between Parallel Plates

1.1K
Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.

Boundary Conditions: Lossless Lines01:21

Boundary Conditions: Lossless Lines

462
Consider a single-phase, two-wire, lossless transmission line terminated by an impedance at the receiving end and a source with Thevenin voltage and impedance at the sending end. The line, with length, has a surge impedance and wave velocity determined by the line's inductance and capacitance.
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...

Principle of Linear Impulse and Momentum for a Single Particle01:20

Principle of Linear Impulse and Momentum for a Single Particle

2.0K
Linear momentum is a fundamental concept in physics that describes the motion of an object. It is a vector quantity, having a magnitude equal to the product of its mass and its velocity, and direction along the object's velocity. On the other hand, linear impulse, also known as momentum impulse, is a concept in physics related to the change in the linear momentum of an object. Impulse is a vector quantity defined as the product of force and the time over which the force is applied.

Summary

Active particles in narrow channels form dynamic clusters or mimic passive motion, depending on their diffusion type. This activity offers an advantage for self-propelled particles navigating confined spaces against external forces.

Area of Science:

  • Physics
  • Soft Matter Physics
  • Statistical Mechanics

Background:

  • Single-file conditions in narrow channels restrict particle movement and enhance correlations.
  • Active Brownian particles exhibit self-propulsion and rotational/translational diffusion.

Purpose of the Study:

  • To investigate the impact of activity on particle behavior in single-file channels.
  • To compare active Brownian particles with classical passive systems under confinement.

Main Methods:

  • A minimal two-dimensional model of active Brownian particles.
  • Analysis of particle dynamics influenced by translational and rotational diffusion.

Main Results:

  • Active particles form continuously merging and splitting clusters (active clusters) when rotational diffusion dominates.
  • When translational diffusion dominates, active particles replicate passive motion paradigms.
  • Activity provides an advantage for self-propelled particles to overcome external biases in narrow channels.

Conclusions:

  • Particle activity significantly alters dynamics in single-file systems, leading to novel collective behaviors like active clustering.
  • Self-propelled particles gain a competitive edge in confined environments due to their inherent activity.
