Cold atoms offer a glimpse of flat physics
Posted by Xavier Rosseel in categories: computing, particle physics, quantum physics
These days, movies and video games render increasingly realistic 3D images on 2-D screens, giving viewers the illusion of gazing into another world. For many physicists, though, keeping things flat is far more interesting.
One reason is that flat landscapes can unlock new movement patterns in the quantum world of atoms and electrons. For instance, shedding the third dimension enables an entirely new class of particles to emergeâparticles that that donât fit neatly into the two classes, bosons and fermions, provided by nature. These new particles, known as anyons, change in novel ways when they swap places, a feat that could one day power a special breed of quantum computer.
But anyons and the conditions that produce them have been exceedingly hard to spot in experiments. In a pair of papers published this week in Physical Review Letters, JQI Fellow Alexey Gorshkov and several collaborators proposed new ways of studying this unusual flat physics, suggesting that small numbers of constrained atoms could act as stand-ins for the finicky electrons first predicted to exhibit low-dimensional quirks.

Happy holidays! The winter break is here, and LEAF too will shift to a lower gear for a little while, but on the plus side, our readers get the Rejuvenation Roundup early! Before we leave you to unwrapping presents and having dinner with the family, letâs recap what has been going on in the field of rejuvenation during the last month of the year.

Water on Mars PICTURED: ESA shares incredible IMAGES of Martian ice crater
Posted by Michael Lance in categories: futurism, space
HUGE skating rink?
The European Space Agency has shared an incredible composite image showing a 50-mile wide crater on Mars that is filled with water ice all year long.
Budding future colonists hoping for a white Christmas on Mars will be somewhat disappointed as the ESA has confirmed that sitting in the Korolev crater is, in fact, a thick block of water ice, not snow. The enormous, 82-kilometer-wide, 2-kilometer-deep âice trapâ could still be good for ice skating though.
