Dr. Levi and his collaborators published the article of Quantum fluctuations in small lasers, Phys. Rev. Lett. 102, 053902 (1-4) (2009).
In this talk, he started from basic and led audience into this specific topic. The talk was very focused on the topic. I wish many of you were there.
Welcome back, everyone! I hope you all had a great summer, researching, studying, travelling, etc. 
Yesterday we had our first department colloqium, which was given by Dr. Melko from University of Waterloo. Dr. Melko did really good job in organizing his talk, and if you are interested in his other talks, please kindly go to this link.
References from yesterday’s talk (partial) are as follows.
Quotes:
“There is no perfect solar model.”
“standard model is good, but not perfect.”

First of all, I wanted to thank Prof. Lu and Lisa for helping me schedule this seminar to our department. How wonderful! Especial thanks went to Prof. R. Thompson who did research of my bio and introduced me to audience as if I were an very important person, which was such an honor!
I was impressed to see my seminar was well attended. Thank you all to be there! I was even glad that we had such a lively discussion about USC Libraries services and resources, which helped me know where to go and how to provide you services and resources.
Some concerns from audience in the seminars were
It was also good to know that
last but not the least, I want to thank you all again! Please keep in mind that I am your librarian. Please do feel free to contact me for any questions, concerns and advice you might have.
Let’s build Norah’s ideal library together!
Dr. Heijnsbergen, editor of PRL, came to USC and gave a presentation to help USC physics researchers and students understand in-depth of publishing issues within PRL.
Dr. Heijnsbergen began his seminar by collecting questions from audience. Prof. Johnson and many were very interested to know current acceptance rate of PRL, especially the number for domestic researchers. The other biggest concern from audience was the on-line submission system of PRL, which is not user-friendly according to some users’ experience.
During the presentation, Dr. Heijnsbergen gave different statistical information to USC users, which answered the question 1. It showed that the acceptance rate for domestic researchers has not changed much, while due to faster research growth of other regions, especially researchers from Pacific Rim have been sumbitting a lot. User also questioned how PRL keep itself as pinnacle in the field, if there are more and more articles published. Dr. Heijnsbergen admitted that it was not easy for anyone. To help users know more about peer-review process of PRL, he then explained it to audience step by step, which was my first time to go through with an insider.
Overall it was a very informative presentation. As Dr. Heijnsbergen hoped that it can “culminate in a lively debate about the imminent changes in the landscape of scientific publishing”, I think he did it.

Dr. Yap gave a wonderful talk of nanotubes in both carbon and non-carbon aspects. I personally enjoyed the talk very much, which started with introducing every individual research field, and then discussed the topic in-depth, particularly “vertically-aligned carbon nanotubes (CNTs), boron nitride nanotubes (BNNTs), ZnO nanotubes (ZnO NTs), and Si nanotubes (SiNTs)”.
If you’d like to know more about Dr. Yap’s research, please visit his research group.
The talk covers almost all research fields Dr. Yap has been working on, so his publication page is the best resource for afterwards learning. Here is Dr. Yap’s publication work page.
