)
1 edition published in 2005 in English and held by 6 WorldCat member libraries worldwide The inaugural lecture was given by Professor Steven Chu, Nobel Laureate in Physics, from the Lawrence Berkeley National Laboratory, USA. He highlighted that physical scientists and engineers are devoting considerable attention to biological problems. The better appreciation of the physical and mechanistic aspects of biological systems have provided a deeper, quantitative understanding of how biological systems work

Polymer dynamics of the coil-stretch transition phase transitions and hysteresis
by Steven Chu
(
)
2 editions published between 2004 and 2012 in English and held by 4 WorldCat member libraries worldwide Prof. Steven Chu, Dept. of Applied Physics, Stanford University discusses the dynamics of a single molecule which has striking similarities to phase transitions of many body systems. All two dimension flows are described as a mixture of elongational (E) and rotational (Omega) flows. In 1974, de Gennes predicted the existence of a first order phase transition from a coiled to an extended state for all flows where E> Omega. Furthermore, the extension would exhibit hysteresis with different critical values depending on the past history of the polymer. In the special case where E = Omega, this transition would "soften" and become a second order phase transition. Single molecule experiments have been used to map out the phase diagram of two-dimensional flows. We have observed the sudden phase transition in both elongational and mixed flows. By visualizing individual molecules, a physical picture of how the transition softens to a second order transition is revealed. Hysteresis and dramatic fluctuations near a critical point are also observed

Cooling and Trapping of Atoms and Particles
(
)
3 editions published between 1995 and 2004 in English and held by 3 WorldCat member libraries worldwide We showed that it is possible to cool atoms in a one dimensional optical lattice using to a novel degenerate sideband cooling technique. This method was then extended to a three dimension optical lattice. With this method, we are able capture all the atoms in a MOT and directly cool them to the photon recoil temperature at phase space densities of 1/500 using low powered (20 mW) diode laser beams. This represents a 2 1/2 order of magnitude increase in phase space density over the best form of grey optical molasses

Laser cooling, trapping and the applications to atom interferometry, quantum gases & biology
by Steven Chu
(
Visual
)
1 edition published in 1992 in English and held by 2 WorldCat member libraries worldwide Lasers can be used to trap and manipulate neutral particles. These can be used in a wide range of applications. Steve Chu, Stanford University, discusses the use of atom interferometry to measure the acceleration of an atom due to gravity and photon recoil with high sensitivity. He also presents a method of cooling which is used to cool Na atoms in one dimension to an effective temperature of 100 nK, a factor of 10 below the recoil limit. He ends with a discussion of an application in biology, where optical tweezers are used to test models for muscle contraction

Atomic Fountain Microwave Clock
(
)
1 edition published in 1994 in English and held by 1 WorldCat member library worldwide The grant as in support of a research program to explore the possibility of a microwave atomic clock based on an atomic fountain of cesium atoms. During the two year granting period, the following work was done: A large magneto-optic trap in a vapor cell was constructed where over 4x 10(exp 10) atoms were trapped at a density on the order of 10(exp 11) atoms/cu cm. This work increased the number of atoms optically trapped by a factor of -400 compared to previous work. The optical density of the atoms in this trap has a peak attenuation of e( -175). In an invited review article we examined the prospects for slow atom frequency standards. Most of the systematic effects that limit the current accuracy today's frequency standards decrease as the velocity of the atoms is reduced. We identified the one possible exception: collisions between ultra-cold atom in an atomic fountain could induce a phase shift that would ultimately limit the accuracy of the fountain clock. We brought the problem to the attention of B. Verhaar, who began a series of calculations on the effects of low energy collisions. jg p.4
The role of fluctuations in biology
by Steven Chu

)
1 edition published in 2006 in English and held by 1 WorldCat member library worldwide Steven Chu, Director, LBNL and Professor of Physics points out that in "What is Life", a set of lectures delivered in 1944, Erwin Schrodinger states "from all we have learnt about the structure of living matter, we must be prepared to find it working in a manner that cannot be reduced to the ordinary laws of physics [not because] there is any 'new force', but because the construction is different from anything we have yet tested in the physical laboratory." Professor Chu briefly discusses how this prediction fared 60 years after these lectures were given. With the advent of molecular, structural and single molecule biology, we are developing an increasingly mechanistic understanding of bio-molecular systems. The molecular machinery of life is imbedded in a viscous fluid where friction and thermal fluctuations are huge. In particular, studies of RNA enzymes such as the ribosome and other ribozymes show that their construction and operation is different than human designed machines that work in an environment where fluctuations and dissipation are minimized
