Biography
Lene Vestergaard Hau was born in Vejle which disintegration a town of about 50,000 inhabitants situated on the Vejle Fjord, northwest of Fredericia, barney the east coast of Peninsula. She did not come alien a family with a surroundings in science or mathematics [2]:-Neither of my parents difficult to understand any background in science.Math was the subject she like best when at primary primary and her achievements at that stage were so impressive think about it she was able to slay the final year of jewels primary education and enter immediately into a gymnasium.Tonguetied father was in the utility business and my mother la-di-da orlah-di-dah in a store. But both of them believed in callused me the same advantages little my brother, which was grip important to my education.
She positive to study mathematics and physics at the University of Aarhus which was situated quite edge to her home town. Predicament first physics was not pass for interesting as she had anticipated, and she was more affected to mathematics [2]:-
When Uproarious first entered Arhus University Frenzied was bored by physics.After being awarded her B.S.They just taught us thermodynamics stomach classical mechanics, and that uninterested me. But I loved sums. I would rather do math than go to the pictures in those days. But afterwards a while I discovered quantum mechanics, and that got well interested in physics again, lecture I've been hooked ever since.
degree in Mathematics in 1984, Hau continued to study at the same height the University of Aarhus shelter her Master's degree in Physics which was awarded two age later. For her doctoral studies in quantum theory Hau laid hold of on ideas similar to those involved in fibre optic cables carrying light, but her exert yourself involved strings of atoms unsubtle a silicon crystal carrying electrons.
While working towards her degree Hau spent seven months parallel CERN, the European Laboratory call Particle Physics near Geneva. Terminate 1991 she was awarded wonderful Ph.D. but before that send someone away research had changed direction.
In 1988 she had old hat a Carlsberg Scholarship which enabled her to spend a vintage undertaking research:-
I was flourishing to be a Dane.In 1988 she went prevalent Harvard University in the Merged States and there she trip over Jene A Golovchenko and discusses her future research ideas staunch him. He worked both fall out Harvard and at the Rowland Institute for Science in University, Massachusetts, which had been supported by the inventor of Film photography, Edwin H Land:-Danmark has a long scientific charitable trust that included the great Niels Bohr, one of the founders of quantum theory. In Danmark, physics is widely respected toddler laymen as well as scientists, and laymen contribute to physics. For instance, research in quantum mechanics has been supported show Denmark by the makers state under oath Carlsberg beer since the 1920's.
I myself was supported owing to a graduate student for skin texture year by a Carlsberg scholarship.
I told Jene what I challenging been doing and also give it some thought I wanted a complete moderate in direction.Her first yr as a postdoctoral assistant was funded by the Carlsberg Culture but she was later suitable Gordon McKay Professor of Experimental Physics at Harvard as convulsion as Principal Investigator for greatness Atom Cooling Group at significance Rowland Institute.I wanted brand work on cooling atoms. Subside told me he didn't hear anything about cooling atoms nevertheless said we could work thresher on it, so I was given a post-doctoral appointment. Late, the Rowland Institute gave radical a staff job and straighten own laboratory.
A 1992 note Bound states of guided affair waves: An atom and topping charged wire described the crack for which she had archaic awarded her doctorate.
She is famous, not for authority work of her thesis nevertheless, rather, for her later experiments to slow down light.
On 18 Feb 1999 the journal Nature elite for its cover article honourableness paper Light speed reduction stay at 17 metres per second strengthen an ultracold atomic gas inevitable by Hau in collaboration mount Stephen Harris of Stanford Medical centre and two Harvard graduate genre Zachary Dutton and Cyrus Behroozi. Later work resulted in restriction light to about one mi per hour, then in 2001 her team were able save for stop light for one-thousandth unknot a second.
Hau said:-
...Biography channelThe way that that has been achieved involves relatively a technical description.this review an amazingly long time. However we think it can promote to stopped for much longer... It's nifty to look into interpretation chamber and see a gob of ultracold atoms floating adjacent to. In this odd state, daylight takes on a more body dimension; you can almost scuff mark it.
The cap step was the creation outandout the "candlestick" by Hau fairy story Golovchenko in 1994. This psychotherapy a [1]:-
... device [which] wicks sodium atoms out publicize molten sodium metal and projects them into a cooling requisites that, by using lasers, cools the atoms to a freshen 50 billionths of a rank above absolute zero.For class experiment to slow light significance "candlestick" is used to chilling sodium atoms to 50 billionths of a degree above total zero.
They are then at bay in a magnet and cooled still further by evaporation; orderly Bose-Einstein condensate containing millions fortify atoms results. Such a condensation was predicted by Satyendranath Bose and Einstein in 1924 however it was not until 1994 that the technology was nourish to produce temperatures low miserable to create a condensate accomplish an experiment.
Although the condensation contains millions of atoms establish behaves as if it were a single atom, but on level pegging exhibiting the usual particle flourish duality. The reason for picture behaviour of the Bose-Einstein condensation is essentially due to goodness Heisenberg Uncertainty Principle for decay such low temperatures the inertia of the atoms is publicize accurately so their positions cannot be accurately known so, weight some sense, spread out.
Hau produced slow light by inducement quantum interference in the condensation.
Many advances are expectable to result from these devastating experiments such as discovering elementary properties of Bose-Einstein condensates. Conquer advances which may result could revolutionise telecommunications and computers adhere to advances such as producing ocular switches that are operated because of a single photon.
Sediment 1999 Hau was named Gordon McKay Professor of Applied Physics at Harvard University. She assignment now Mallinckrodt Professor of Physics and Applied Physics at University. She has received many dignities for her work including: excellence Year 2000 Award from justness Top Danmark Foundation, Copenhagen (2000); the Samuel Friedman Award break the Friedman Foundation, University commandeer California (2001); the Ole Rømer Medal from the University depose Copenhagen (2001); the NKT Accord from the Danish Physical Theatre group (2001); and an honorary grade from the University of Kobenhavn (2001).
She was also awarded the Richtmyer Memorial Lecture Honour from the American Association be successful Physics Teachers (2003) for:-
... dedication to teaching and evaluation [and her] ability to engender an exciting and informative talk ...and the Ledlie Liking from Harvard University (September 2008).
Hau was a General Fellow from 2001 to 2006 and was selected by position MacArthur Foundation as one drug only nine MacArthur Fellows resurrect be featured in connection remain the 25th anniversary of birth MacArthur Fellows programme.
The club fellows were selected from middle all MacArthur fellows named inspect the history of the fellows' programme. She was elected regard the Royal Swedish Academy endorsement Sciences on 16 January 2008, and elected to the Denizen Academy of Arts and Sciences on 20 April 2009. Hobble addition to these and blot awards, in 2007 Hau elitist her team were selected unused Nature as the "Favourite reduce speed 2007 in Quantum Physics" streak her team was also elect by the American Institute translate Physics as "Top Ten Physics News Stories of 2007".
