You are right. I will eventually have to pick something. Though what do you suggest writing in the description part of the application where I need to address "specific area in this subject that appeals to you, specific problems, if any, that you would like to work on, your background and...

I see what you mean. You had a starting point and that was AMO. But for me I don't really have anything to start with and well I don't have any previous research experience either. I kind of want to explore "String theory and Quantum Gravity" but I don't think I have the required skill set for...

Well, active scientists isn't really the problem. At this stage I am confused about which field to pick because I have no preference and maybe want to explore. The problem is these program applications demand for very specific interests which I don't have at the moment. And so filling up the...

I am a third year physics major doing my undergrad. First, let me give you an idea on my academic background. We just picked our majors this year, meaning before we had to take other courses like courses from Biology, Chemistry, etc. This year I'll be taking courses like Classical mech, Quantum...

It illustrates the superposition theorem in quantum mechanics which states that if there are two or more quantum states, then they can be superposed to get a new valid quantum state. So, if a cat can be dead or alive, then the cat being dead and alive is also a possibility.

So, it's essentially just multiplying the wavefunction you have just before turning off the potential with the free particle propagator and integrating over all space as stevendaryl put it.

If your wavefunction is discontinuous, then how can your first derivative be continuous? Further, the second derivative will be discontinuous and so your Schrodinger equation will be ill-defined.

There is no such meaning to an eigenvalue here. Also here the eigenvalue happens to be an eigenvalue of a non-hermitian operator and so has no "physical interpretation". Although it's a characterization of coherent states. You can take a look at Cohen-Tannoudji, there they have started out with...

I'm a junior in college. I'm learning quantum mechanics these days. Physics is love, physics is life!
