Re: [Wien] extrnal magnetic field effect
You are absolutely correct, also the magnetic field breaks periodic symmetry. In addition, it is even much MORE complicated than an electric field, because it is gauge-dependent, (origin) The magnetic field acts an both, the spins (via Vxc up/dn, and this is included correctly), and on the orbitals, introducing an orbital current and a resulting magnetic field. The latter is included in this option only in a "single site central field (atomic)" approximation in a VERY crude way. I don't know if this approximation is good enough to give you at least roughly the effect you are looking for. Don't expect "quantitative" agreement at all. PS: In the new NMR code, we apply a magnetic field rigorously, but I'm afraid only the effect on the wavefunctions (and the resulting current) is calculated, but not a change of eigenvalues. Robert: can you comment on that ?? -- Dears Prof. Blaha and Martin Pieper Thanking you for your reply again >Sorry, my mistake. I thought you are using an electric field. I studied the PRB. 63 165205 (2001) paper, that is about the electric field case. In this paper has been noticed that: “A general problem in calculating crystal properties in an external electric field is that the total potential V =V_int +V_ext in the Hamiltonian” (equation 1)” is no longer periodic. V_int is the periodic potential caused by all charged particles within the crystal, while V_ext is the external potential from external charges (outside the crystal). The translational symmetry of the wave function is broken and from this point of view the solid is no longer an ideal crystal. A locally homogeneous external electric field may be simulated by introducing a potential with a period several times the lattice parameters of the crystal” And in the section V (DFT CALCULATIONS) We can see that a supercell and periodic potential to maintain periodic boundary condition have been used as V_ext where its Fourier summation is Eq.12. My questions are Does the external magnetic field change the periodic boundary conditions similar to the electric field? If it does, why do we use the unit cell ? If it doesn’t, what is the difference between electric and magnetic field? -- Peter Blaha Inst.Materials Chemistry TU Vienna Getreidemarkt 9 A-1060 Vienna Austria +43-1-5880115671 ___ Wien mailing list Wien@zeus.theochem.tuwien.ac.at http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien SEARCH the MAILING-LIST at: http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/index.html

Re: [Wien] extrnal magnetic field effect
Dear Majid Yazdani. As for the unit cell: I never did the Ce example, but you should consider how the field you applied fits into local symmetries. As for the electronic structure changes: Apply a field B0 large enough to have g*mu_B*B0 >> E_convergence of your SCF. When you calculate the field you might want to thank Peter Blaha that fields of that size are so cheap in Wien2k. Then blow up the resolution in your DOS-plot when you look for field effects. As for the changes in the DOS of FM and AFM phases I am not sure what exactly you mean. Experimental results or DFT calculations? Materials with a field induced magnetic transition?
