從聲子出發(fā)只是其中一條路,而且涉及到準(zhǔn)簡(jiǎn)諧近似的限制。從分子動(dòng)力學(xué)出發(fā)不一樣,可以得到很多很多熱力學(xué)性質(zhì)。MD卻是耗時(shí),要不然也不會(huì)發(fā)展更加優(yōu)化高效的方法了。這些都是相對(duì)的,涉及到熱力學(xué)平衡的問(wèn)題,就必然涉及到動(dòng)力學(xué)問(wèn)題。 |

今天受到了Paolo在mailist里面的信,給大家看看,了解一下新功能。Paolo私下告訴我下一步Pwscf發(fā)展的重點(diǎn)就是分子動(dòng)力學(xué),到時(shí)候會(huì)把最近的分子動(dòng)力學(xué)進(jìn)展比如langevin molecular dynamics加進(jìn)去。 Version 4.3 of the Quantum ESPRESSO distribution is available for download from the website http://www.quantum-espresso.org . This release contains the following improvements over previous versions: * vdW-DF - Dispersion interactions (van der Waals) with nonlocal functional in PWscf (Brian Kolb, Timo Thonhauser, Riccardo Sabatini, SdG) * New package TDDFPT for calculations of spectra using Time-Dependent Density-Functional Perturbation Theory (SB, Ralph Gebauer, Baris Malcioglu, Dario Rocca, Brent Walker) * Additions to projwfc: k-resolved DOS, LDOS integrated in selected real-space regions * Constant-volume variable-cell optimization * Non-colinear and spin-orbit PAW * CP only, experimental: parallelization over Kohn-Sham states * CP only, experimental: penalty functional technique in DFT+U calculations Note the following major change: * code pw.x no longer performs NEB calculations. NEB is now computed by a separate code, NEB/neb.x . NEB-specific variables are no longer read by pw.x; they are read by neb.x after all pw.x variables * NEB for cp.x no longer available For other minor improvements, changes, bug fixes, see file Doc/release-notes Everybody who is using the Quantum-ESPRESSO distribution is encouraged to upgrade and to report problems to the mailing list.
