Re: [Pw_forum] LDA+U and noncolin lspinorb : hub file not written?

2018-02-04 Thread Christoph Wolf
Dear all, sorry for the late response; the problem seems to be that I have specified only one k-point. The system complains about gamma tricks but not about a single k point (1 1 1 0 0 0), when I double the k points the files are properly written! Thanks for your help! Chris On Thu, Jan 25, 201

[Pw_forum] tefield vs lelfield: physics of gated graphene

2018-02-04 Thread Christoph Wolf
Dear all, I was wondering which approach would be better suited to describe an efield applied across a 2D system with surface normal in z direction. Judging from the docs both can be used to apply a field but I am curious if one has an advantage over the other. I further found the "gatefield" exam

For graphene I would try first the sawtooth potential (option "tefield"): it is simple and does the job (as long as you place it in the proper position). Paolo On Sun, Feb 4, 2018 at 1:04 PM, Christoph Wolf wrote: > Dear all, > > I was wondering which approach would be better suited to describ

Re: [Pw_forum] phonon dispersion by using optimized tetrahedron method

Dear Dr. Mitsuaki Kawamura, Thank you! How can I run lambda.x in optimized tetrahedron method? Since in this method, no .inp_lambda.xx file is not generated. So how can I calculate projected dos, as matdyn.x gives total dos? On Sat, Feb 3, 2018 at 10:27 PM Mitsuaki Kawamura < mkawam...@issp.u-t
