So you mean that I should take each portion appart (where f(x) is constant) and calculate the integral. Then, I add them all together ?
Is there any other method where I can calculate Fourier series normally and then I multiply them by another factor which will make them increase or decrease ?
Hello, can we make a Fourier series expansion of a (increasing or decreasing) step function ? like the one that I attached here. I just want to know the idea of that if it is possible.
This is the refference to the article that I'm working with :
Huria, Tarun, Massimo Ceraolo, Javier Gazzarri, and Robyn Jackey. "High fidelity electrical model with thermal dependence for characterization and simulation of high power lithium battery cells." In Electric Vehicle Conference...
Thanks sir for your responce, but what I want to know why the term of spin-magnetic field interaction doesn't appear in the hamiltonian of the electron. is it because it is so small in front of the kinetic energy for example ?
Hi, in the case of free electrons gas under the effect of a magnetic field. The hamiltonian of an electron doesn't contain a term of Spin-Magnetic field interaction this means that it contains just the kinetic energy terms. Why is that ?
What do we mean by break points in band structure ? and what that sentence means : "if the band index were chosen in such a way that the energies are indexed in ascending order for any k then break points would appear in the εnk vs. k plot (with n fixed) wherever two lines intersect." ...
Can you give the name of an excited book of solid state / condensed matter physics ( beside kittel and ashcroft ) ? a book than contains more talking about experimental rather than theory
What is the best physics journal for condensed matter physics ?
And what is the best journal for all branchs of physics that keeps you on update ?
Thanks
One of the classes of the group C5v is written C=(2*C5). So why do we mean by 2*C5 and how we can know the elements of this class from this writing ?
Thanks
Mod note: This post was moved from a different thread.
Why the point group C1h is identical to C1v ?
Why the point group C1h with horizontal twofold axis is identical to C2v ?
Thanks
Thank you very much krylov and Zapper Z for your answers. I just want to tell you that I finished my first three years as undergraduate student, now I'm about to start my first msc year in condensed matter physics, but I'm not satisfied with my study method. So I understand from what you have...
OK guys this is an exemple of sourcemeter unit : http://www.es-france.com/produit538/product_info.html , But what I want to know is what means CURRENT LIMIT physically.
We see always in source meter machines a LED which indicates the limit current. I want to know what is the limit current and what is the relationship between this later and the resistivity.
First of all I'm sorry for the late of replying, Vanhees71 Thank you for the answer you really helped me and ChrisVer I asked a question for you to help me or to correct me if I was wrong, and thank you for you too for the notice.
