Undergrad What is the meaning of superposition of momentum in coherent states?

Click For Summary
The discussion centers on the concept of superposition in coherent states, specifically regarding momentum and position. It highlights the distinction between how wave functions are expressed for calculating probabilities of position versus momentum measurements. The superposition reflects the mathematical representation of various probabilities for measurement outcomes. The conversation emphasizes that regardless of the focus on position or momentum, superposition fundamentally represents the different potential results of measurements. Understanding this distinction is crucial for grasping the underlying principles of quantum mechanics.

What is the meaning of the coherent states superposition of momentum?
Good night. I have a doubt, what is the meaning of the coherent states superposition of momentum?
In a many of places, sites I see an explanation for the equations but I never see the explanation between diffences of the superposition of position from momentum.

One way we're writing the wave function in a form that makes it easy to calculate the probability that we'll measure a particular position for the particle if we make a position measurement; the other way we're writing it in a form that makes it easy to calculate the probability that we'll measure a particular momentum for the particle if we make a momentum measurement

But either way, superposition is just the way that the math captures the different probabilities of getting the possible measurement results.

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
