--></style><div class="WordSection1"><p class="MsoNormal">To All Within the PWscf Community:</p><p class="MsoNormal"> </p><p class="MsoNormal">Yesterday I was honored to be invited to have lunch with Walter Kohn, one of four in the company of Ted Geballe, Steve Kivelson and Mac Beasley of the Applied Physics Faculty of Stanford. I believe the QE community would enjoy knowing that Walter, at age 88, is very active and engaged, especially in promoting wind and solar as the future energy scenario of the US (not one I totally agree with, BTW). I first met Walter in the late 1970s when I was at IBM and collaborating with Doug Scalapino on Monte Carlo simulations of low dimensional fermion Hubbard-like models.</p><p class="MsoNormal"> </p><p class="MsoNormal">We did get a few minutes to discuss the future of DFT as well, and agree that our community would benefit greatly from the extension of LDA+U, particularly to electron-phonon
interactions. Nicola? Mateo? Eyvaz?</p><p class="MsoNormal"> </p><p class="MsoNormal">-Paul</p></div></div></div>
