Laser Cooling of Atoms
Information sheet 2 Laser cooling of atoms In 1985, Alain Aspect joined Claude Cohen-Tannoudji, professor at the Collège de France (Chair of atomic and molecular physics), at the Laboratoire Kastler-Brossel (ENS Paris/CNRS/Université Paris VI), and embarked on research into the laser cooling of atoms with Jean Dalibard, and later with Christophe Salomon, physicists at CNRS. The aim is to control the movement of atoms, by using the force of radiation pressure exerted by lasers. It turns out to be possible to reduce the speed of atoms down to extremely low values, in the region of a few centimeters per second. The gas thus obtained has an extraordinarily low temperature: around one microkelvin, which is only a millionth of a degree above absolute zero. Among the many results obtained at ENS and which were rewarded in particular by the 1997 Nobel prize awarded to Claude Cohen-Tannoudji2, Alain Aspect especially contributed to the development of the first cooling method which made it possible to slow down the speed at which atoms move to below the “photon recoil”. This is the speed gained by an atom which emits a photon, rather like a gun recoiling when it is fired. The photon recoil was considered at that time to be an unsurmountable barrier. Note that the process used to obtain this result (dubbed “velocity-selective black resonance”) Cooling of atoms to “below photon recoil”. This leads to each atom being placed into a quantum shows the tracks left on a fluorescent screen by superposition where it is simultaneously present in several hundred atoms which were cooled and several areas of space that are a few centimeters released above the screen. -
Bose-Einstein Condensation
Low Dimensional Systems and Nanostructures Jon Ander Arregi Bose-Einstein Condensation A Bose-Einstein condensate is a state of a dilute gas, sometimes also called fifth state of matter, of weakly interacting bosons (i.e., particles with integer spin) confined by an external potential and cooled down to temperatures very near to the absolute zero. At low enough temperatures the system undergoes a transition to a state with a large fraction of the bosons occupying the lowest energy level, corresponding to a zero momentum state, at which quantum effects become apparent on a macroscopic scale. In 1924, the indian physicist Satyendra Nath Bose was working on the quantum statistics of light quanta (nowadays called photons) but he had troubles getting people to accept his ideas. He sent his results to Albert Einstein, who realised of the importance of his work and he translated and sent Bose's paper for publication [1]. Einstein extended the description for massive particles and he found out that something very unusual was supposed to happen at very low temperatures [2]. It was not until 1995, after decades of huge efforts seeking for the experimental evidence, that the first realization of the Bose-Einstein condensate of a gas of around two thousand 87Rb atoms cooled down to 170 nanokelvin (nK) was made by Eric Cornell, Carl Wieman and co-workers at the University of Colorado at Boulder [3]. Four months later, the group led by Wolfgang Ketterle at MIT created a condensate of 23Na with a hundred times more atoms [4], allowing him to observe important effects such as quantum mechanical interference between different condensates [5]. -

In this document, we describe how detailed studies of stellar dynamics deep in the potential well of a galaxy offer several exciting directions in the coming decade. First, it will be possible to obtain precision measurements of the Galaxy’s central potential, providing both a unique test of General Relativity (GR) and a detection of the extended dark matter distribution that is predicted to exist around the SMBH. Tests of gravity have not previously been pos- sible on scales larger than our solar system, or in regimes where the gravitational energy of a body is >∼1% of its rest mass energy. -

A Mathematician's Journey to the Edge of the Universe "The only true wisdom is in knowing you know nothing." ― Socrates Manjunath.R #16/1, 8th Main Road, Shivanagar, Rajajinagar, Bangalore560010, Karnataka, India *Corresponding Author Email: [email protected] *Website: http://www.myw3schools.com/ A Mathematician's Journey to the Edge of the Universe What’s the Ultimate Question? Since the dawn of the history of science from Copernicus (who took the details of Ptolemy, and found a way to look at the same construction from a slightly different perspective and discover that the Earth is not the center of the universe) and Galileo to the present, we (a hoard of talking monkeys who's consciousness is from a collection of connected neurons − hammering away on typewriters and by pure chance eventually ranging the values for the (fundamental) numbers that would allow the development of any form of intelligent life) have gazed at the stars and attempted to chart the heavens and still discovering the fundamental laws of nature often get asked: What is Dark Matter? ... What is Dark Energy? ... What Came Before the Big Bang? ... What's Inside a Black Hole? ... Will the universe continue expanding? Will it just stop or even begin to contract? Are We Alone? Beginning at Stonehenge and ending with the current crisis in String Theory, the story of this eternal question to uncover the mysteries of the universe describes a narrative that includes some of the greatest discoveries of all time and leading personalities, including Aristotle, Johannes Kepler, and Isaac Newton, and the rise to the modern era of Einstein, Eddington, and Hawking. -
BEC) in Alkali Atoms Masatsugu Sei Suzuki Department of Physics, SUNY at Bimghamton (Date: January 24, 2012)
Bose-Einstein condensation (BEC) in alkali atoms Masatsugu Sei Suzuki Department of Physics, SUNY at Bimghamton (Date: January 24, 2012) In 1925 Einstein predicted that at low temperatures particles in a gas could all reside in the same quantum state. This peculiar gaseous state, a Bose–Einstein condensate (BEC), was produced in the laboratory for the first time in 1995, using the powerful laser-cooling methods developed in recent years. These condensates exhibit quantum phenomena on a large scale, and investigating them has become one of the most active areas of research in contemporary physics. _________________________________________________________________________ The first gaseous BEC was generated by Eric Cornell and Carl Wieman in 1995 at the University of Colorado at Boulder NIST-JILA lab, using a gas of Rb atoms cooled to 170 nK. For their achievements Cornell, Wieman, and Wolfgang Ketterle at MIT received the 2001 Nobel Prize in Physics. In November 2010 the first photon BEC was observed. _________________________________________________________________________ Carl Wieman was born in Corvallis, Oregon in the United States and graduated from Corvallis High School. Wieman earned his B.S. in 1973 from MIT and his Ph.D. from Stanford University in 1977; he was also awarded a Doctor of Science, honoris causa from the University of Chicago in 1997. He was awarded the Lorentz Medal in 1998. In 2001, he won the Nobel Prize in Physics, along with Eric Allin Cornell and Wolfgang Ketterle for fundamental studies of the Bose-Einstein condensate. In 2004, he was named United States Professor of the Year among all doctoral and research universities. http://en.wikipedia.org/wiki/Carl_Wieman Eric Allin Cornell (born December 19, 1961) is an American physicist who, along with Carl E.
