Congratulations, PhD Alina Hriscu
Alina has finished our rough four-year long jeep ride and has obtained her title today. The defense was very good, and she has been complimented by every committee member, something that is rather exceptional.
Can somebody blog about the party? I'd really appreciate.

Congratulations, Yaroslav!
By decision of College van Bestuur of our university Yaroslav Blanter has been promoted to the rank of full professor, Antoni van Leeuwenhoek hoogleraar . Well-deserved and long-awaited promotion. This decision, although irreversible, is not yet officially announced and will be implemented by steps, the last one will be an official speech of Yaroslav in about a year. So I sincerely hope we will celebrate the event several times :)

Giorgi's PhD defence
As many of us know Giorgi got his PhD degree on Monday, after a relatively painless one hour procedure. The committee members tried to do their best to embarrass him with the questions, but he managed to answer all of them in a satisfactory manner. It is said that the party was great success, running well over midnight, and that Akash succeeded in getting some staff members to dance, but I had to leave early and was only represented by the voice record. Giorgi will stay with us until the beginning of November, and then will start looking for a job in the Netherlands. Congratulations.

New PhD Student
My name is Olya. I've just started my PhD with Yaroslav this Monday. Originally, I am from Ukraine, Kiev, but my Bachelor I did in Taiwan, in not such a big city Hsinchu which is famous for its Science Park, one of the world's biggest semiconductor manufacturing. I'm living in the Netherlands already for 2 years since in August 2012 I got my Master's diploma in Theoretical Physics from University of Amsterdam. Project was about integrability and based on Bethe Ansatz for one-dimensional spin chain. Hopefully some time later the publication will come from it. Now, I am almost done with all administrative procedures here and reading some papers for the new project which will be about interaction of the mechanical resonator with the Josephson bifurcation amplifier.
In the time I am not doing Science, I like jogging, dancing and riding bike to different cities and places in the Netherlands of course if it is not raining. Sometimes, I would play table tennis or volleyball.
That's a little bit about myself and hope soon I will know you all better!
From Victor Boogers
Let me introduce myself
I'm a
bachelor student of the fourth year and am doing my Final Bachelor
Project with Jos Thijssen. I hope to start with the master Applied Physics
(with the track Quantum Nanoscience) this year and one of the things I
still need to do is this project. I hope to finish somewhere in the
beginning of december.

Joost de Gussem
Most of the people within TP know or remember Joost de Gussem, who did
his bachelor project in our group.
Joost completed his master project last Tuesday (28 August) under the guidance of Erin McGarrity. The title
of the thesis was no less than "A study of liquid-vapor systems of weak multipoles using classical DFT". The
title may be seen as a premonition of the lengthy complicated mathematical analysis which in the end leads
to very good agreement with molecular dynamics simulations on polar fluids. The main message in a nut-shell
was that taking the local structure of the fluid into account via the correlation function is essential for a reliable
description of the fluid-gas interface.
After the exam, Joost was awaited by an exclusively female fan club, who was pleased to hear that he had done very well, with a good mark as a final result.

Adriaan Vuik's project
Yesterday Adriaan Vuik presented his bachelor thesis work on quantum key distribution with time-energy entangled photons. In a clear talk he explained that quantum mechanics can help to realize secure key distribution and how time-energy entangled photons can be at the basis of this. After thorough questioning, Adriaan has now finished the very last part of his bachelor programme and will start with his master, also in Delft, next week. Congratulations and good luck!

Akashdeep Kamra
has given a talk at our group meeting today. It was about interaction of magnons and phonons in the context of spin transfer. The results oultined are as follows:
1. Linear Magneto-Elastic Coupling (MEC) leads to an avoided level crossing in the (quasi) magnon and (quasi) phonon branches of the dispersion relation at which a new quasi particle - magneto polaron is formed.
2. We observe that linear MEC forms the basis of already known effects such as acoustic ferromagnetic resonance and predicts some novel effects such as acoustically assisted magnetic switching.
3. Non-linear MEC is responsible for energy exchange and equilibration between phonons and magnons thereby forming the basis of effects such as the spin Seebeck effect.

Bachelor eindproject Ferdinand
With some delay, about bachelor defence of Ferdinand. He impressed us with his presentation that had some elaborated structure and provoked deep and provocative questions: given the fact that it was perhaps the first presentation of a kind in his life. During the closed part of the defence, he answered quickly and correctly on my classic question about the rainbow, a question no master student could answer without substantial hints. With this, and his persistence and enthusiasm during the project time no wonder he got a pretty good mark.
Good luck, Ferdinand, with your master studies!

Graduation Sasja
This afternoon Sasja defended her Bachelor thesis after a five months stay
in our group. She performed calculations on the shot noise in a normal metal-insulator-superconductor junction in graphene and gave a very clear presentation on this, which provoked quite some questions from some of our PhD students. After discussing her results further with the committee she has now completed her Bachelor research project in Delft and will shortly move on to do a physics Master programme in Belgium.
Congratulations, Sasja!

Theory seminar August 8
Dear All,
let me try and see whether it is easier to put an announcement here than to send the e-mail around.
August 8 (Wednesday), 14:00, Olga Shevchuk from University of Amsterdam will give a talk in Gerrit's room

August 8 (Wednesday), 14:00, Olga Shevchuk from University of Amsterdam will give a talk in Gerrit's room
Transfer matrix as powerful tool to solve the gapless XXZ model
Abstract:
Bethe Ansatz is widely used to describe
thermodynamic properties of certain one-dimensional quantum many-body
models. One such model is the gapless spin-1/2 anisotropic Heisenberg
chain with periodic boundary conditions. In my talk I
will start from some basic introduction to the Bethe Ansatz and proceed
with numerical method of solving Bethe equations of this model which is
based on exact diagonalization, transfer matrix, and polynomial-fitting.
In the end, I will show you some of the
results that was obtained by this method. The findings show that the
transfer matrix is able to describe all eigenstates of the system.
Olga is a candidate for a PhD position. I may also ask a couple of you to talk briefly to her.

Friday, 20 July 2012
From Jos Thijssen
on Monday, after Alina's talk, we all went down to hear and Chris Drost's
master presentation.
Chris has worked on quantum signatures of phonons in the coupling of a molecule to leads.
A substantial delegation of Chris' family was present. It is not (yet) clear what they picked up from
Chris' talk, but they were certainly happy to hear that Chris had completed the procedure, including a
thorough questioning, very successfully. So there is a new qualified theorist on the loose in Delft.
Congratulations, Chris!

Group meeting July 16
We have started group meetings of the second half of the year in a new, less formal location with the talk of Alina Hriscu. She told about her recent results in synchronization of Josephson and Bloch oscillation. She gave a nice general intro mentioning fireflies. The talk was unfolding prefectly, with interesting details and provoking questions. Unfortunately, there was time pressure owing to the master thesis presentation of Chris that was scheduled later today. So that the talk has become a bit sketchy in the end.

good book. discount. For you?
Dear Colleagues,
Cambridge University Press has now offered discount promotion on my book
"Field Theory of Non-Equilibrium Systems", which was published last Fall.
http://www.cambridge.org/us/knowledge/discountpromotion/?site_locale=en_US&code=L2FTNS
It is devoted to modern functional methods in non-equilibrium theory and
their applications to quantum and classical problems of many-body physics.
I worked hard to make it relevant, pedagogical and self-contained. Hope
that your students and post-docs may find the book educating and useful
for their research.
Sincerely,
Alex Kamenev
