A decent part of today was spent in conversation with friends and colleagues, but here are some high points of scientific talks:
- The DMP prize session was excellent. The first talk was by Harold Hwang, this year's awardee of the McGroddy Prize. He gave a very compelling review of his group's accomplishments doing epitaxial growth of perovskite oxides, ranging over early work on colossal magnetoresistance compounds, designing conducting interfaces, understanding polar catastrophes, attempts at delta doping, creating free-standing oxide membranes, and most recently "de-intercalating" to create nickelate superconductors. I also appreciated the quote from Herbert Kroemer, "If, in discussing a semiconductor problem, you cannot draw an energy band diagram, this shows that you don't know what you are talking about."
- The next talk in that session was by Nitin Samarth, this year's awardee of the David Adler lectureship, all about semiconductor spintronics. Again, a great collection of topics, including Mn-doped II-VI materials, the inspiration of the Datta-Das spin transistor idea, Ga(Mn)As as a ferromagnetic semiconductor, optically injected spin transport in non-magnetic semiconductors, topological insulators for spin-charge conversion, quantized anomalous Hall response, and topology+superconductivity.
- Then Matteo Mitrano, winner of the IUPAP prize, gave a nice talk about time-resolved x-ray measurements, particularly of photo-induced metastable states of correlated materials. These included time-resolved resonant inelastic x-ray scattering (trRIXS) and time-resolved x-ray absorption spectroscopy (trXAS).
- In another session, I saw a very nice talk by Chia-Ling Chien about spin Seebeck response in the non-collinear antiferromagnet LuFeO3, including results on spin-swapping, when the spin current direction and the spin index orientation can swap, predicted theoretically 15 years ago.
- I also was able to see Steve Simon's presentation about unusual "spiral Kekule order" in bilayer graphene, and Mike Manfra's talk about anyon interferometry (here and here) in 2D electron gases.
More tomorrow....
In what context was Kroemer's quote used? HH was not discussing semiconductors... (I stayed home this year).
ReplyDeleteHi Doug, I am not there. Could you or someone else stop by the Oxford University Press booth and see if they are selling my book,
ReplyDeleteCondensed Matter Physics: A Very Short Introduction?
I am curious to know how good their marketing department is.
Peter, it was in reference to understanding band offsets at oxide interfaces. Ross, I will try to take a look tomorrow and let you know. I haven't looked over the publisher tables in any detail (though I did check to see that Cambridge had a copy of my book :-) ).
ReplyDeleteI see another reason to go to the March meeting... Check if my book is for sale...
ReplyDeleteRoss, unfortunately I have to inform you that they don't have copies of your book at their booth, and your book also does not show up on the list of titles that they have as for sale at the meeting. (They did have one copy of "superconductivity: a very short introduction" there.) It does show up on the OUP site if I search for it, but somehow it doesn't seem to be linked to their APS meeting stuff.
ReplyDeleteHi Doug, Thanks so much for checking. This confirms my worst fears about their marketing department. They asked me to fill out a detailed questionnaire about marketing the book, including what professional meetings they should sell the book at. Of course, I said the March Meeting. I will follow up with them. Cheers, Ross
