I actually thought of that, and it would be an interesting project, but I feel like I don't really have the necessary skills for something like that. Maybe in the future, when I have completed my PhD :D I know that, unfortunately most of the codes used in my field do not use GPUs yet (although...

Hello! As the title states, I want to get myself a new rig for simulating complex physical phenomena. Specifically, I'm going to run quantum chemistry/solid state physics/atomic physics calculations on it. I'm planning to re-use some parts of my old PC, and buy some new ones. I want to spend...

M. W. Ray, E. Ruokokoski, S. Kandel, M. Möttönen & D. S. Hall,"Observation of Dirac monopoles in a synthetic magnetic field", Nature 505, 657-660 (2014), doi:10.1038/nature12954 Magnetic monopoles—particles that behave as isolated north or south magnetic poles—have been the subject of...

I was so happy when I saw this. I the fact that the cat w.f. is properly normalized cracked me up.

Hello guys, Recently I came across a definition to which I'd never given much thought. I was reading through Gelfand and Fomin's "Calculus of variations" and I read the part about weak and strong extrema, and I really can't manage to wrap my head around these definitions. They can be found in...

My thoughts exactly. I will never understand this, this seems to be an obvious problem to everyone else except to a lot of Americans, who seem to be selectively blind to it. I actually feel more free knowing that people don't go around armed, it's the freedom of not being afraid to get shot. And...

Wild guess here, but wouldn't it have to do with larger angular momentum of the states composing the valence band?

Blindsight is a sci-fi novel by Canadian writer Peter Watts. I haven't finished reading it yet (although I've read about 90% of it), and I alredy know it's one of the best novels I've read in a while. It's about a near future (21st century still) in which humans make contact with alien...

Well, I was looking for something relatively modern, or at least with modern editions. Thanks for replying. Anyone read this one: https://www.amazon.com/dp/1842654489/?tag=pfamazon01-20

I think that's a problem faced by teachers in general, from biology to philosohpy, from physics to art. :D When I took advanced math classes in high school, the focus of the classes shifted from a purely 'calculatory' approach to something with more demonstrations and abstract concepts. That...

How am I supposed to know I don't know my stuff well enough before someone shows it to me? What I learned is that when a system is in a superposition of states and you make a measurement on it, then it collapses into some eigenstate as we make our measurement (the textbook stuff). How is it...

Honestly, I haven't heard of them. And I don't know what you mean by being "adamant", everyone is convinced of what they believe in until they aren't. And quite frankly, what you're defending is not exactly a widespread view (even if it might be correct), in fact if I google "Delft/Stony Brook...

How so? I'd never heard about that, but I'll check it out. Sure, but you haven't observed it either. I'm sorry, no need to get all up in arms about it. I was taking an unassuming position to respond to a guy who was obviously rambling because wether or not superposition is real it has...

I feel like he's trolling us. Repeating stuff he read somewhere else without understanding it.

Hello, could someone recommend a good book on tensor calculus? I'd like it to be relatively modern (I have an old book) and maybe contain some examples drawn from physics. Chapters on related subjects such as differential forms and calculus of variations would be a plus. Cheers.
