Postdoctoral Position at Washington University in St. Louis on Atomistic Modeling of Chalcogenides

A one-year postdoctoral position with possible extension up to two years is available in the Materials Modeling & Microscopy (M-cube) group of Rohan Mishra at Washington University in St. Louis, beginning immediately. The successful candidate will use first-principles density-functional-theory (DFT) calculations for developing structure-property correlations in chalcogenide materials.
We are currently interested in quasi-one-dimensional (1D) chalcogenides for their optical and thermal properties, and 2D chalcogenide alloys for their electrocatalytic activity. The successful applicant is expected to develop quantitative structure-property-processing correlations to enable the design of new 1D and 2D chalcogenides for optical, thermal and electrocatalytic applications. These projects are part of multi-university collaborative efforts and involve extensive collaboration with experimentalists focused on the synthesis and characterization of these materials. The successful applicant is expected to work closely with our collaborators.
Applicants must have a recent Ph.D. in Materials Science, Physics, or a closely related field with demonstrated expertise in using DFT calculations to develop structure-property correlations in functional materials. Prior experience of developing phenomenological models from first-principles calculations will be a bonus. The applicant should be able to work independently and in a team. Candidates with strong programing skills (using Python, Fortran or C/C++) will be preferred.
The successful applicant will have ample opportunities for career development. They are expected to be involved in co-mentoring graduate and undergraduate researchers, present their research at conferences, and develop independent research directions.
Interested candidates are encouraged to apply by emailing a single PDF file containing: (1) a cover letter (not more than one-page) with a summary of accomplishments and future research interests; (2) CV (with a list of all publications); and (3) names of three references to rmishra@wustl.edu.
Screening of applications will start immediately and will continue until the position is filled.

As the crackdown on SciHub and LigGen/Z-Lib intensifies the platforms to open the access to papers and books in PDFs are moving to the deep web. The Telegram Bots, nevertheless, keep working fine.

SciHub: @scihubot or https://news.1rj.ru/str/scihubot
Z-Lib: @zlibrary2bot or https://news.1rj.ru/str/zlibrary2bot

Knowledge should be free.

Surface Hopping including Arbitrary Couplings developed by the González group

The SHARC molecular dynamics (MD) program suite is an ab initio MD software package developed to study the excited-state dynamics of molecules.

* can treat non-adiabatic couplings at conical intersections, intersystem crossing induced by spin-orbit coupling, and laser couplings on an equal footing.
* can treat any number of states of arbitrary multiplicities.
* has interfaces to MOLPRO, MOLCAS, COLUMBUS, ADF, TURBOMOLE (only ricc2), GAUSSIAN, ORCA, BAGEL, analytical potentials, and linear-vibronic coupling potentials.
* comes with the WFoverlap program for efficient computation of nonadiabatic couplings and Dyson norms.
* can do QM/MM simulations with MOLCAS, ADF, TURBOMOLE, and ORCA.
* can do on-the-fly wave function analysis through TheoDORE.
* comes with the PySHARC extension for very efficient dynamics simulations with linear-vibronic coupling potentials.
* includes auxiliary Python noscripts for setup, maintenance and analysis of ensembles of trajectories.
* includes noscripts to perform excited-state (crossing point) optimizations and single point calculations with all interfaced methods.
* has a comprehensive tutorial.

OPEN ACCESS
DFT exchange: sharing perspectives on the workhorse of quantum chemistry and materials science

In this paper, the history, present status, and future of density-functional theory (DFT) is informally reviewed and discussed by 70 workers in the field, including molecular scientists, materials scientists, method developers and practitioners. The format of the paper is that of a roundtable discussion, in which the participants express and exchange views on DFT in the form of 302 individual contributions, formulated as responses to a preset list of 26 questions. Supported by a bibliography of 777 entries, the paper represents a broad snapshot of DFT, anno 2022.
