    Band structure and fermi liquid

    Hi tirrel, As the Hartree-Fock method is a method for the determination of the ground-state wave function and ground-state energy of a quantum many-body system, basically it is suitable for calculating the ground-state wave-function of a Fermi-liquid. Take a look at this article...

    Is a reference frame fixed to a photon an Inertial Frame?

    Thanks for your help JesseM! It was my thoughtlessness... Clearly, I can't make use of a theory based on postulates, if I try to answer something which does not obey them. My question was illogical, I'm sorry. Regards

    Is a reference frame fixed to a photon an Inertial Frame?

    Hi All, I am a bit confused about reference frames and inertial frames. According to the first postulate of special relativity (if I'm right), all physical laws take their simplest form in an inertial frame, and there exist multiple inertial frames interrelated by uniform translation...

    Questions about IMEC's PhD Admissions for Non-EER Countries

    Thank you for your answer, yoran! I've been searching for this abbreviation for like weeks, but I haven't thought of it beeing a Dutch one :). Thanks

    Which programming language do you use?

    You can take a look at calling NAG from Java through JNI here if you are interested: http://www.nag.com/doc/TechRep/html/Tr1_04/Tr1_04.html"

    Which programming language do you use?

    This is true. But mainly for early Java, as you wrote. I don't think, however that mathematical libraries have been implemented in Java in great number:( By the way, NAG (and I guess some other) libraries can be called from Java code. I don't know how efficiently, though.

    Which programming language do you use?

    Does anyone uses Java for serious problems? By the way, thanks for the quick replies!

    Which programming language do you use?

    Hi All, I am a physicist from Hungary. I was involved in quite a few programming tasks back in the university, especially in the field of Density Functional Theory, which needed complex computations. I used Fortran and later C++, for Object Oriented programming gave quite a few advantages...

    Questions about IMEC's PhD Admissions for Non-EER Countries

    Hi all, I was thinking about continuing my studies in physics. I read through the docs about IMEC's PhD topics and I found the list quite impressive and interesting. I have masters in physics and I took the GRE general, so I guess I fulfill some of the requirements... (Well, at least...
