Re: [Pw_forum] Relaxation of coordinates in TDDFT
Dear Andreas, It is not possible to relax atomic coordinates in excited state with the TDDFPT package. Best regards, Iurii -- Dr. Iurii Timrov Postdoctoral Researcher Swiss Federal Institute of Technology Lausanne (EPFL) Laboratory of Theory and Simulation of Materials (THEOS) CH-1015 Lausanne, Switzerland From: pw_forum-boun...@pwscf.org on behalf of Andreas Röckert Sent: Wednesday, December 21, 2016 8:24 PM To: pw_forum@pwscf.org Subject: [Pw_forum] Relaxation of coordinates in TDDFT Hi All, I have used TDDFT in Quantum espresso to estimate the charge density response, however i need to relax my atomic coordinates in excited state (i.e in the presence of time dependent fields). I was wondering if TDDFPT or any other package of Quantum espresso is able to do that? Do you have any suggestions for me?

I think CPMD can do MD on excited-state surfaces Paolo On Thu, Dec 22, 2016 at 9:43 AM, Timrov Iurii wrote: > Dear Andreas, > > > It is not possible to relax atomic coordinates in excited state with the > TDDFPT package. > > > Best regards, > > Iurii > > > -- > Dr. Iurii Timrov > Postdoctoral Researcher > Swiss Federal Institute of Technology Lausanne (EPFL) > Laboratory of Theory and Simulation of Materials (THEOS) > CH-1015 Lausanne, Switzerland > > > From: pw_forum-boun...@pwscf.org on behalf of > Andreas Röckert > Sent: Wednesday, December 21, 2016 8:24 PM > To: pw_forum@pwscf.org > Subject: [Pw_forum] Relaxation of coordinates in TDDFT > > Hi All, > > I have used TDDFT in Quantum espresso to estimate the charge density > response, however i need to relax my atomic coordinates in excited state > (i.e in the presence of time dependent fields). > I was wondering if TDDFPT or any other package of Quantum espresso is able > to do that? > Do you have any suggestions for me? > > Thanks > Andreas > > Chemistry department > Uppsala university > > ___ > Pw_forum mailing list > Pw_forum@pwscf.org > http://pwscf.org/mailman/listinfo/pw_forum -- Paolo Giannozzi, Dip.

[Pw_forum] Dudarev DFT+U version
Hello, Q.E. users Is the DFT+U scheme (lda_plus_u_kind = 0) similar to the Dudarev DFT+U version (simplified rotational invariant, PRB, 57, 1505), which means whether the U term (lda_plus_u_kind = 0) is an effective U (that is, U_eff = U-J) or not? Thank you in advance. Evan USC, China___ Pw_forum mailing list Pw_forum@pwscf.org http://pwscf.org/mailman/listinfo/pw_forum

[Pw_forum] file formats of p_avg.dat
Hi everyone, I am told that band.x program can output momentum matrix elements. However, I cannot make sense of the output file p_avg.dat. For example, I think momentum matrix elements should be generally complex, but I see no such indications in the output file. So, what's the format of p_avg.dat? Best!
