Photoelectric Effect02:26

Photoelectric Effect

40.9K
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...

Coulomb's Law01:30

Coulomb's Law

12.4K
Experiments with electric charges have shown that if two objects each have an electric charge, they exert an electric force on each other. The magnitude of the force is linearly proportional to the net charge on each object and inversely proportional to the square of the distance between them. The direction of the force vector is along the imaginary line joining the two objects and is dictated by the signs of the charges involved.
Newton's third law applies to the Coulomb force — the...

π Electron Effects on Chemical Shift: Overview

1.9K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...

Coulomb's Law and The Principle of Superposition01:15

Coulomb's Law and The Principle of Superposition

11.9K
Coulomb's Law describes the force experienced by two point charges under each other's presence. But what if there are more than two charges? For example, if there is a third charge, does it experience a force that is a simple combination of the individual forces due to the first two charges? Can it be described mathematically?
The Principle of Superposition answers the question. Yes, Coulomb's Law applies to each pair of charges, and the net force on each charge is the vector sum of...

Energy Associated With a Charge Distribution01:21

Energy Associated With a Charge Distribution

2.0K
The work done to bring a charge through a distance r is given by the potential difference between the initial and the final position. To assemble a collection of point charges, the total work done can be expressed in terms of the product of each pair of charges divided by their separation distance, defined with respect to a suitable origin. Solving this expression gives the energy stored in a point charge distribution.

The de Broglie Wavelength02:32

The de Broglie Wavelength

34.3K
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...

Area of Science:

  • Strong field atomic physics
  • Quantum dynamics
  • Laser-matter interactions

Background:

  • The influence of long-range Coulomb interactions on intense laser-driven atomic processes has been largely overlooked.
  • Previous experimental studies have not fully captured the role of this interaction in photoelectron dynamics.

Purpose of the Study:

  • To experimentally investigate the effect of the long-range Coulomb potential on near-zero-momentum photoelectrons.
  • To understand the dynamics of photoelectrons produced in noble gas atoms under intense mid-infrared laser pulses.

Main Methods:

  • Experimental investigation of photoelectron distributions near zero momentum.
  • Systematic variation of laser intensity and wavelength.
  • Photoionization of noble gas atoms using intense mid-infrared laser fields.

Main Results:

  • Demonstrated the significant role of the long-range Coulomb potential (extending to hundreds of atomic units) on photoelectron dynamics.
  • Observed clear dependence of photoelectron distributions on laser intensity and wavelength.
  • Unambiguously showed the Coulomb potential's impact on photoelectron behavior after the laser pulse.

Conclusions:

  • The long-range Coulomb tail is a critical factor in shaping photoelectron dynamics post-laser pulse.
  • Experimental evidence confirms the importance of considering Coulomb interactions in intense laser-atom interactions.
  • This finding advances the understanding of strong-field atomic physics and photoelectron spectroscopy.
