    Dft Tensor
AI Thread Summary
The discussion centers on finding free resources for learning Tensor Calculus and Density Functional Theory (DFT). While Tensor Calculus is acknowledged as challenging and typically learned through formal education, several resources for DFT are recommended. A notable introductory paper on DFT is available at arXiv, and for a more comprehensive understanding, the book "Methods of Electronic Structure Calculations" by Michael Springborg is suggested, as it covers both physics and chemistry perspectives. Additionally, a resource from Burke's group at Rutgers offers a PDF and PS format introduction to DFT, along with links to relevant Nobel lectures. The conversation emphasizes the wealth of DFT literature available online, particularly since the mid-1980s, for those with access to journal archives.

Someone helps me !
I'm looking for where I can download free e-print about Tensor Calculus and Density Functional Theory . I want to teach myself.

Thank you very much .
 
Mathematics news on Phys.org
While I can't help with learning tensor calculus (I learned my tensors in class and through a number of agonizing problems), I can offer some help with DFT.

http://www.arxiv.org/abs/physics/9806013 A somewhat short intro to DFT. I will say if you're interested in a more thorough treatment, more modern applications of DFT, or a combination thereof you'll have to dig up the references mentioned. There is a reason why entire books on DFT have been written. A nice little book on electronic structure calculations that I happen to really like is Methods of Electronic Structure Calculations by Michael Springborg. It goes over both physics-oriented and chemistry-oriented methods, unlike some texts which only cover one or the other in any kind of detail.

I will say as an additional note that a great deal of DFT literature has been published since the mid 1980s and you can find quite a bit online in journal archives if you have access.

Good luck with DFT and may your experience be less traumatic than mine trying to learn it. :)

Added after edit: I should have remembered this intro to DFT by Burke and his group at Rutgers. You can find it http://dft.rutgers.edu/kieron/beta/index.html in PDF and PS format, along with a link to the Nobel lectures presented on DFT a few years back.

Thread 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Thread 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
