Elektromagnetic field ~ probability amplitudes

In summary, the conversation discusses the relationship between the components E and B of an electromagnetic field and the probability amplitudes of a Schrödinger wave function for the same field. The question is posed whether it is possible to derive the probability of registering a photon within a certain volume and time interval based on the E and B field, and whether there is any missing information in this approach. It is also noted that the electromagnetic field cannot be interpreted as a single-particle wave function in the same way as massive particles in non-relativistic quantum mechanics.

Given an electromagnetic field by its components E and B. How is this related to probability amplitudes of a Schrödinger wave function for the same field.

Trying the same or at least a similar question from a different angle: given the E and B field, can we derive from it, in principle, not considering solvability, the probability of registering a photon within a certain (small) volume and time interval?

If not, which piece of information is missing. Yet another angle on the question: do the E and B field contain all the information for the probabilities or is there something missing?

The electromagnetic field is a relativistic massless spin-1-field. There is no physically sensible interpretation of it as a single-particle wave function as for massive particles in non-relativistic (Schrödinger) quantum mechanics. There is not even a proper position operator for photons!
 

FAQ: Elektromagnetic field ~ probability amplitudes

1. What is an electromagnetic field?

An electromagnetic field is a physical field that is created by electrically charged particles and is responsible for the interactions between charged particles, including the force of attraction or repulsion between them.

2. How is an electromagnetic field measured?

An electromagnetic field is measured using a device called an electromagnetic field meter, which measures the strength and direction of the field. This measurement is typically given in units of volts per meter (V/m) or tesla (T).

3. What are probability amplitudes in relation to an electromagnetic field?

Probability amplitudes, also known as wavefunctions, are mathematical functions that describe the behavior and interactions of particles in an electromagnetic field. They represent the probability of a particle being in a certain location or having a certain energy at a given time.

4. How is probability amplitude related to the uncertainty principle?

The uncertainty principle states that the more precisely we know the position of a particle, the less precisely we can know its momentum, and vice versa. Probability amplitudes are used to calculate the probability of a particle's position and momentum, and thus they are directly related to the uncertainty principle.

5. Can an electromagnetic field be manipulated?

Yes, an electromagnetic field can be manipulated using various methods such as changing the strength of an electric or magnetic field, altering the shape of the field, or using materials with specific properties to interact with the field. This manipulation can be used for various purposes, including communication, energy production, and medical treatments.
