I am reading this paper: https://arxiv.org/abs/0708.4025. In section 2, they describe a classical black hole as a classical randomizer. The black hole initially is a ##n-k## bit string, and Alice sends a ##k##-bit string into the black hole. A permutation of all ##2^n## possible strings is the...

Thanks for the suggestion, I'll check it out.

In particular I would like to have a resource for the relation between group theory, crystal field symmetries and breaking of degeneracies of orbitals. I've taken a graduate condensed matter course and graduate quantum mechanics courses. I have some basic knowledge of group theory but can learn...

There are many groups in quantum information who might offer (paid) internships. I found mine through emailing professors, including my transcript and resume. Are you in America?

The integral equation is T(x_3,t_3|x_1,t_1)=\int \text{d}x_2T(x_3,t_3|x_2,t_2)T(x_2,t_2|x_1,t_1) where T(x_3,t_3|x_1,t_1) is the probability density of a Markov process taking the value x_3 at time t_3 given that it took the value of x_1 at time t_1. So far so good. To derive the differential...

If your main interest is quantum information then since you have a little background in QM I would just pick up Nielson and Chuang's book which is the standard in QM. They cover a little bit of the QM necessary at the beginning as well as some linear algebra. Knowing in depth details about...

Hello, I am interested in learning more about photosynthesis. My background is in physics, mostly condensed matter and atomic physics (graduate level). I have not taken a chemistry course since high school but I am looking for a book that starts from a physics point of view anyway. What are some...

I applied to the pure physics program (never heard of the applied physics program until I got an email saying I was accepted to it). My statement of purpose was focused on applications of physics to nanophotonics and quantum information so I guess I can see why they recommended me for applied...

Why is it paired with materials science? I have not been able to find too much about it online apart from their own stuff. How different is it from their pure physics PhD program? It seems that they have a lot of required courses, although you do not need to take them if you have a sufficiently...

Im having a bit of trouble when it comes to what the abstract object S1 actually is. Often in a book they will mention a parametrization of the circle in the complex or real plane. But this requires embedding the circle in Euclidian space. How should one think of the object S1 without thinking...

This is not exactly what you are asking for but I think this is also a good opportunity to practice youre numerical computing skills (which you will need whether you do experiment or theory). What I did when I took my first quantum class was to just look at some numerical solutions to...

Thanks for the book reference. As for learning both at the same time, i wasnt too worried about the techniques and abstraction in modern dg since I have already studied topology. But thanks for the suggestion, ill keep it in mind.

Thanks for the reference, the one by Millman and Parker seems to be quite close to what I'm looking for.

I'm mostly interested in how it can be applied to QFT and electromagnetism. I've seen the phrase fibre bundle come up a lot. But I also like DG just for the subject itself. Atleast I liked the section on curves and surfaces that I learned about in my calc course.

Im planning on taking a course on classical differential geometry next term. This is the outline: The differential geometry of curves and surfaces in three-dimensional Euclidean space. Mean curvature and Gaussian curvature. Geodesics. Gauss's Theorema Egregium. The textbook is "differential...
