Josh and Feizhi have recently published a paper on the stability of generalized Hartree-Fock (GHF) wave functions. During the solution of a variational problem it is possible to converge to a higher energy minima instead of the global minima. Whenever possible, the stability of the wave function should be confirmed. If the wave function is . . .
Congratulations to our undergraduate student Malte for winning the Mary Gates Research Scholarship! This is a very competitive scholarship awarded to promising undergraduate researchers are UW. Malte is currently working on modeling ion diffusion in quantum dot nanocrystals in order to better understand lithium ion batteries. As part of the scholarship he will be presenting . . .
A recently published paper,”Real-Time TDDFT Studies of Exciton Decay and Transfer in Silver Nanowire Arrays,” focuses on exciton dynamics, transfer, and decay in silver nanowires. One silver nanowire was initially excited and then coupled to a second nanowire with varying separation distances between them. The electronic density of the total system was then propagated in . . .
The group’s first publication of 2015 details work in an area we have been interested in for some time: including environmental response in our simulations. The Polarizable Continuum Model (PCM) is often used to account for the dielectric response of the media surrounding the molecule of interest. Previous attempts at time-dependent PCM only accounted for . . .
The group is happy to welcome Franco Egidi. Franco recently finished his Ph.D. with Vincenzo Barone and Chiara Cappelli at Scuola Normale Superiore in Pisa. He has published a number of papers on environmental effects, optical rotation, and vibrational spectroscopy. Franco is a welcome addition to the group and will be a big help on . . .
Congratulations to Erica on passing her General Exam. Erica presented her work on using a Discrete Variable Representation (DVR) to describe ion mobility in quantum dot nanostructures. Congrats to Erica!
Josh Goings and Feizhi Ding published a paper in the Journal of Chemical Physics titled “Ab Initio Non-Relativistic Spin Dynamics“. The Generalized Hartree-Fock density was coupled to a magnetic field and propagated in real time. This was a non-relativist two-component spinor method, called TDN2C. This method allows for the resolution of non-collinear electron spins precessing . . .
We are pleased to welcome a new graduate student, Sajan Silwal to the group. Sajan originally hails from Nepal and obtained his undergraduate degree at Kalamazoo College in Michigan. There he did some experimental work looking on photodissociation, but became interested in programming and decided to switch to theory for graduate school. Welcome Sajan!
