Ultracold Physics

can this possibly preserve life? i mean can they freeze an animal then store it for a certain period of time then take it out and let it live again?

It is very very far from now. As of now, specific atoms and molecules that have very friend light-matter interaction are being used. If you also read about it briefly, the condensate is very very small around micrometers in size. It's implications are in probing quantum mechanics, studying condensed matter systems and the recent news I posted which is on Quantum Cosmology.

However, freezing an animal is probably impossible for now at least because you will need all matter to interact with light/laser at the same time. This is not possible with solids. Physicists working in this field start with gases then do some procedures with huge lasers setups and they obtain a Bose-Einstetin condensate which is very very very cold!

To give you an idea how their laboratory looks like. Check out the link below.

Quantum Munich:Move to Munich

It is the leading laboratory in this field led by Prof. Dr. Immanuel Bloch. You can also check out other stuff from their media section. They have videos and more.

This video will enlighten you about this topic. http://www.youtube.com/watch#!v=7Y0w...eature=related hehe

mao ni organic computers.

OT..who says it ain't cool to be a nerd? =)

suspended animation or human hibernation technology is still light years away. chances of getting THAWED due to constant brown-out is a very big problem for now =)

OT: Hahahaha! that is true. It's ultracool! hahaha!

Back to topic: That is true. I don't really know what the requirements are but I think the freezing process should be very very quick, "Flash Freezing." Also, as you said, the temperature must be maintained. Brown-outs can be easily remedied. All you have to do is too isolate your subject in a ultralow pressure vaccum chamber.

Anyway, the field in this thread was never really intended for this application. When the 1st physicists achieved this, they didn't think about cryogenics but instead with the mysteries of quantum mechanics. hehe!

^mao

so this is al about , controlling the movement of molecules .

i think na news ni before! naa person ni volunteer para mo preserve sa iyang self

Hello Guys! I've been travelling all over Europe looking for a PhD position. I went to places that have invited me for an interview. Some of the highlights are in Munich, Germany and Vienna, Austria. I visited the famous MAX PLANCK INSTITUE!!!!!!!! I was very much blown away and intimidated. I went to the 10 hectare land comprising different divisions of the Max Planck Institue. I only visited one (Max Planck Institute for Quantum Optics) but I passed by other divisions, Astrophysics, Extraterrestrial physics, etc..



At the Max Planck Institute for Quantum Optics, I visited Prof Blochs section (http://www.quantum-munich.de/). I also got a chance to meet the famous Nobel price winner Theodor Hansch (Theodor W. Hänsch - Wikipedia, the free encyclopedia) who is the director of the institute. Of course, I got an interview, I gave a talk about my masters thesis and I also got a huge laboratory tour. It was an amazing experience. I saw things I've never seen before it's like the LHC but with OPTICS. Their research is really extraordinary when it comes to Ultracold Atoms. They have achieved the quantum simulation of superconductors and quantum insulators. Anyway, I won't go into detail about their research. Bottom-line is that they are one if not the best in the business.

Unfortunately, I didn't get a response from them. So I am assuming I didn't get the PhD position. Fortunately, one of their physicists there who I got to befriend was kind enough to refer me to other research groups. I applied to 5 other places and one of them invited me for an interview. This is in the institute of atomic and subatomic physics at the Technical University of Vienna. This research group is also comparable to the Max Planck Institute for Quantum Optics. Their boss, Prof Schmiedmeyer is one of the front-runners in ultracold atomchips. The have huge cryogenic chambers along with crazy optical trapping and cooling techniques. One of their goals is to couple superconducting qubits (quantum bits) into an ensemble of Ultracold atoms. It's a crossover between Solid State Physics, Condensed Matter Physics and Quantum Optics. The ultimate goal is create a Quantum Memory for Quantum Bits.

Anyway, few days after I visited the group, I received an PhD offer from their boss. I didn't hesitate in accepting it. I will be working on the topic I described in the above paragraph hopefully around October. hehehe I'm so happy to have this position. I just would like to share my scientific endeavor experience. I made 20 applications and only around 5 of them responded. hehe

choy lage ni. basahon unya ko ni if naa ko oras..

@ fritzd: wow, congratulations! blow them away, sir

Hello Guys! I have something new to share. It's poster for our laboratory open house where people visit our labs. It shows some photos and progress of our experiment. It's pretty cool. I have already started my PhD around a month ago. The things I am learning and need to learn is overwhelming. Anyway, I hope you find the poster informative as well as interesting.

FYI: I didn't make the poster. The Senior PhD researcher in our group, Stephan Haslinger made it.
