Tailoring the optical dipole force for use on molecules

first_img(PhysOrg.com) — “Scientists have been working with dipole fields for quite some time,” Peter Barker tells PhysOrg.com. “However, most of the work is focused on very small particles, like atoms, or on larger particles, such as for use as optical tweezers. There is an interim region between atoms and large particles, and that is what we are looking at. We want to be able to control molecules a little differently.” This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Barker is a professor at University College London, and has been working on a process by which an optical field can be used to align molecules. Along with Simon Purcell, Barker has found a way to not only align molecules through the tailoring of the optical dipole force, but to also move them around. “This is, we believe, the first time that alignment and the ability to move molecules around have been brought together using the dipole force,” Barker says. Barker and Purcell report their work in Physical Review Letters: “Tailoring the Optical Dipole Force for Molecules by Field-Induced Alignment.”“In order to do this, we have a gas sitting at a relatively high pressure in a chamber. Using strong optics, we send a beam through the chamber, forming a hole of sorts. The optical field acts as a tractor beam, grabbing the molecules present in the gas and bringing them to rest. This makes them ultra cold,” Barker explains. Laser cooling in a similar fashion has been done with atoms for quite some time. It is standard practice for many experiments. However, Barker says that it is harder to produce ultra-cold molecules than it is to bring atoms to a state of rest. “This could provide a way to cool molecules to just above absolute zero, which is of interest for a number of research applications.”The process introduced by Barker and Purcell could also have use as a way to separate rotational states. “In some cases, scientists want to be able to separate out different states. Unfortunately, there is a whole range of molecules that can’t really be singled out in this way. With our dipole tailoring process, though, it is possible to separate out these states. We could also separate molecules of different types.”Another use for this process could conceivably be the use of light to focus molecules onto a particular surface. “We haven’t done this yet, but it should be possible get molecules to act as a lens, and then rotate the polarization to change the focus. We think that it should be possible to get features down to the nanometer size by focusing molecules in this manner.”“Being able to tailor the optical dipole force in this way is a big step,” Barker says. “In our experiment, we were able to both align molecules and move them around by tailoring the optical dipole force. Being able to align and position molecules simultaneously is something that hasn’t been done before with this force, and it has a great potential, both for fundamental research, and for possible practical applications.”More Information: S.M.

A BoseEinstein condensate has been produced in space for the first time

first_imgThe device consisted of a capsule containing a chip holding a group of rubidium-87 atoms, electronics, some lasers and a power source. It was activated once the rocket reached an altitude of 243 km, producing a BEC in just 1.6 seconds. Once the BEC was produced, 110 preprogrammed experiments were carried out in the six minutes it took the rocket to fall back to Earth.The BEC produced by the team was the first ever produced in space and marks the start of a new era in BEC research efforts. An international team of researchers has successfully produced a Bose-Einstein condensate (BEC) in space for the first time. In their paper published in the journal Nature, the group describes creating a small experimental device that was carried on a rocket into space and the experiments that were conducted during its freefall.

Space-borne Bose–Einstein condensation for precision interferometry, Nature (2018). DOI: 10.1038/s41586-018-0605-1center_img A Bose-Einstein condensate is a state of matter occurring after gas atoms with very low density are chilled to very near absolute zero and bunch up to form an extremely dense quantum state. Scientists are interested in producing them so that they can test their properties—theory has suggested that they could serve as the basis for highly sensitive sensors. Such super-sensitive sensors could be used to better understand physics phenomena such as gravitational waves. However, producing Bose-Einstein condensates is tricky, because gravity interferes with devices for producing and studying them. The current method involves dropping such devices from towers to allow them to do their work in a zero-gravity environment—but these experiments have just fractions of seconds to operate. Doing these experiments in space would be a much better option due to the microgravity environment.Realizing the potential of a space-based platform for conducting BEC research, the U.S. launched the Cold Atom Laboratory last May, though it is not yet fully functional. In the interim, the researchers with this new effort created a tiny device capable of producing a BEC and conducting a host of experiments on it, which they put aboard a rocket and launched into space. © 2018 Phys.org This document is subject to copyright.

Air New Zealand adds 15600 more seats on Vancouver route

first_img Travelweek Group Share Air New Zealand adds 15,600 more seats on Vancouver route << Previous PostNext Post >> VANCOUVER — Air New Zealand plans to grow its Vancouver-Auckland operation by nearly 20% from January to July 2018.During the first half of the January peak period, the airline will increase services from seven to eight flights per week.Regional General Manager Americas Nick Judd says this extra capacity is a direct result of the increased demand for travel in the South Pacific region and the importance of Vancouver in the Air New Zealand network.“This year marks 10 years since we launched our Canadian service and increasing the frequency of our non-stop service between Vancouver and Auckland means our customers will have more travel options, which is great for Canadians wanting to discover all that New Zealand and Australia have to offer,” said Judd.The route will grow nearly 20% (an extra 15,600 seats) by increasing daily services beyond peak months of December and January into the shoulder season of February, and increasing to five services a week in March and April (up from four) and four weekly services during May – mid-June (up from three).More news:  Kory Sterling is TL Network Canada’s new Sales Manager CanadaAir New Zealand Chief Revenue Officer Cam Wallace says the airline is delighted to be able to offer its customers more scheduled flights to and from Vancouver.“We recognize how popular Canada is as a winter destination for Kiwis. We also see the value in increasing services to New Zealand for Canadian tourists, allowing them to escape the winter and enjoy a chance to experience our beautiful summer and the tranquility of New Zealand through the shoulder season.”center_img Tags: Air New Zealand, New Zealand Friday, August 4, 2017 Posted bylast_img read more
