I'm working on a finite element simulation of the electrostatic potential V(r) in and around semiconductor nanowires, based on solving Poisson's equation. While the details of the problem will follow shortly, the crux of where I run into trouble is that for nanowires it is important to include...

Thanks for the comments, very insightful! To answer your question about the condensed matter, there is indeed an advanced condensed matter course. However, it violently clashes with the quantum information theory course, timetable wise. I might be able to take it the year after though. If I can...

Good day, I'm starting my master in physics, and it's time for me to choose my courses. I've decided that I probably want to pursue the direction of quantum information processing, and I'm trying to pick my courses with that in mind. For my first semester I'll be taking four courses: Quantum...

Good day everyone, I'm in a position I am very thankful to be in, the terrible position of being able to choose between two great programs. The first is the MSc in Physics at ETH Zürich , which is a 90 ECTS (European credit system) program that takes three semesters, or a year and a half...

Homework Statement The problem is as follows. I have two spins, m_S and m_I. The first spin can either be \uparrow or \downarrow , and the second spin can be -1, 0 or 1. Now, I envision the situation as the first spin being on the bloch sphere, with up up to and down at the bottom. What I...

Hmm. Well, I suppose I should have added more context, as looking back at it it is indeed not clear at all what I am trying to say. In the end my question boiled down to which eigenvectors corresponded to what columns of the pauli matrices for a spin 1 particle, which is easily answered. But...

Homework Statement Alright, so this is not exactly a guided homework question. It is a rather intricate problem consisting of many steps, but one of these steps comes down to working out the hyperfine interaction between two spin 1 particles, from a hamiltonian point of view. From what I have...

Hmm, I did indeed not read that one yet. If I understand correctly, what they do is before the sequence of pulses they measure the fluorescence, and then they do this again afterwards, repeat this many many times and from this they deduce the relative population of spin up and spin down, which...

I had a question regarding some text in a paper that I was reading. It had to do with ramsey interferometry, where they initialized a particle in spin up (lets say up along the z axis on the bloch sphere), after which they applied a pi/2 pulse to rotate it 90 degrees around the x-axis, they wait...

EDIT: I left out something of major importance, I want to maximize with respect to a! Good day, I've run into an issue in solving a certain problem with matlab, and I was hoping if anyone could help me out. I am relatively new to matlab, so I don't even know if this is possible, but I...

EDIT: I left out something of major importance, I want to maximize with respect to a! Homework Statement My problem is rather complex, but in the end it boils down to maximizing the fraction Homework Equations With the calculus I know, I can't evaluate these integrals, so I have no applicable...

Hmm, well, I take it that this might not have been the correct forum then. I apologize! Should I instead post it in the homework section?

Good day, I was recently asked to look into the process of thermal annealing of thin metal films in order to induce nanoparticle formation. However, I have been terribly unsuccessful in finding any sources that describe exactly how this works. I understand the basic idea of thermal annealing...

Let me begin by saying that this question had a disclaimer, saying that part a should NOT be done exactly, but in a back of the napkin manner. The idea is to make reasonable assumptions and approximations in order to obtain an answer. Homework Statement Suppose that a certain chemical...

Good day everyone, Let me introduce myself. I am currently in the process of getting everything together to start applying for masters programs in physics, for the year 2014-2015. I am a 20 year old student from the Amsterdam University College, in my third and final year of my physics...
