OK, now I have been admitted at 3 universities, and accepted the offer in one of them, is time to reject the other offers. Is a simple "no, thanks" enough, or universities expect a more polite and complete answer? Maybe telling them where we will be doing our studies, etc? But for other part...

It seems that you asked this four years ago, so I do not think that my answer will be particularly useful for you anymore, but anyway it may be useful for someone else who read this forum. Well, I got accepted to UBC (and Toronto and Mcgill as well) with just 680 in PGRE, and 780 in the...

Hi, I was admited for graduate studies at University of British Columbia, McGill University and University of Toronto. I will be doing astrophysics. Anybody knows something about the physics / astrophysics programs in such universities? Thank you in advance for your answers. P.D. I am an...

Hi. First of all, I hope I will not sound shallow with this questions, but I am sure that most guys in physics at least think about this when choosing a university. After all, we all want to study in nice environment, and for me, a decent gender distribution is an important part of a nice...

OK, I completed squares so the potencial energy part of the hamiltoneal reads: (1/2) mw^{2} [ x + (\lambda/ (m w^{2})) ]^{2} - (\lambda^{2} / 2m). I think that I should now define y as y= x + (\lambda/ (m w^{2})) So that the term reads (1/2) mw^{2} y^{2} - (\lambda^{2} / 2m) So...

Thak you. Well, I think that H|Psi> = (Ho+C)|Psi> = (E+C)|Psi> The the eignevalues are just E+C, where E is the harmonic oscilator energy: E = (n+1/2)\hbar\omega If it is just that it was so easy, but the second part looks more complicated. I made a mistake when I copy the...

Hi, I am preparing for a quantum mechanics exam, and I have this problem that I can`t solve: I have to find the complete energy eigenvalue spectrum of a hamiltonean of the form: H = H0 + c and also another of the form H = H0 + \lambdax^{2} Where in both cases, H0 is the...
