Hello! Does any of you know someone in Paris who is working on Solid State Physics using Quantum Field Theory formalism ? Thank you.

As solid state physics studies the structure of materials, it is often important to study and to understand molecular theory. This means that you should, for instance, know very well the properties of the states of electrons in atoms with more than one proton in the nucleous. You should also...

hi, i don't know how to determine bravais lattice from primitive translation vectors.The problem is as: A crystal with one atom basis, has a set of primitive translational vectors as a1=3i, a2= 3j and a3= (3/2)(i+j+k). What is the bravais lattice.
