Spintronics, Orbitronics, and Physics Beyond
by Dongwook Go
If you're new to spin-orbitronics, you must be very confused for many different terminologies that seem to specify the same effect but from slightly different contexts. Honestely, this is really confusing and was terrible, especially when I had to study this field of research from the scratch in the beginning of my PhD. Just to …

About 2 weeks ago, starting from the end of the vacation, I decided to wake up ealier than usual. I found that I do not have enough time when I can concentrate on one topic without any interruption. Since the lockdown with COVID, messengers like Slack and Skype/Zoom discussion became daily events. While these technologies …
Finally I decided to take a vacation for 2 weeks, which started from the last Monday. I have been working quite hard nonstop for several months since the beginning of the year, and I noticed that the productivity was becoming low and I got easily tired, which is a sign that I need a break. …
During the last week, our group organized a hands-on workshop on the DFT code FLEUR. I participated the workshop as a tutor. I gave two talks and led a hands-on session on the Wannier function. About the talk, one was about the basics of the Wannier function and its interface with the FLEUR code and …

Our group, Peter Grünberg Institut in Forschungszentrum Jülich, is organizing a DFT hands-on workshop. We will cover both theoretical and practical aspects of using the FLEUR code developed by our group. Unfortunately, the registration is already closed, but all the lecture videos will be available on YouTube. I myself also plan to watch all the …

Finally the paper on the orbital Rashba effect in a surface-oxidized Cu has been accepted in the last week. Now you can see the publisehd manuscript in the following link. The major change during the reviews was calculation of various stacking geometries and comparisions (fcc, hcp, bridge, etc.). At the end, they are not very …

While a first-principles calculation is often regarded a synoym for the density functional theory in condensed matter physics, the idea of "first-principles" is more deeper than that. It means that we assume nothing but the most fundamental truth (or something we believe), on which any falsification seems very unlikely at least in the near future, …
Usually when I get enough of something new (a.k.a. "theoretical" discoveries), I start to think about how to put them into paper(s). Since different journals have different styles/directions, I also need to decide which journal to target. I think research results can be divided into the following categories: Introducing new concepts worth enough for whole …
A few weeks ago, I just realized that it's been already 2 years since I came to Germany and started research as a postdoc. It was quite surprising because I didn't feel like so much time passed at all. I suppose it's probably because last years was very special with the start of lockdown. Basically, …
