We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic interactions close to a Feshbach resonance we are able to induce a phase diffusive many-body spin dynamics. We monitor this dynamical evolution by Ramsey interferometry, supplemented by a novel, many-body echo technique. We find that the time evolution of the system is well described by a Luttinger liquid initially prepared in a multimode squeezed state. Our approach allows us to probe the non-equilibrium evolution of one-dimensional many-body quantum systems.

1History of the World War

By Richard J. Beamish and Francis Andrew March

This is a popular narrative history of the world's greatest war. Written frankly from the viewpoint of the United States and the Allies, it visualizes the bloodiest and most destructive conflict of all the ages from its remote causes to its glorious conclusion and beneficent results.<br><br>Two ideals have been before us in the preparation of this necessary work. These are simplicity and thoroughness. It is of no avail to describe the greatest of human events if the description is so confused that the reader loses interest. Thoroughness is an historical essential beyond price. So it is that official documents prepared in many instances upon the field of battle, and others taken from the files of the governments at war, are the basis of this work. All that has gone into war making, into the regeneration of the world, are herein set forth with historical particularity. The stark horrors of Belgium, the blighting terrors of chemical warfare, the governmental restrictions placed upon hundreds of millions of civilians, the war sacrifices falling upon all the civilized peoples of earth, are in these pages.

Aquest audiollibre conté diversos poemes del poeta valencià Ausiàs March. Aquests poemes són especialment coneguts per haver estat musicats pel cèlebre cantautor Raimon. Aquesta tria ha estat llegida per Maria Josep Altadill per a la campanya "Donants de veu", impulsada per la Universitat Oberta de Catalunya amb l'objectiu d'augmentar la presència de la literatura en català en el mon de l'audiollibre. Ausiàs March és la figura capdavantera de la poesia medieval en català, l'obra extensa del qual va ser àmpliament coneguda al seu temps (segle XV) i posteriorment en el conjunt de les literatures hispàniques.<br><br> This audiobook contains several poems by the Valencian poet Ausiàs March. Those poems are well known for being set to music by the famous singer Raimon. This selection have been read by Maria Josep Altadill for the campaign "Donants de veu", organized under the auspices of the Open University of Catalonia in order to make Catalan literature more widely available in audiobook format. Ausiàs March is the leading figure of Medieval Catalan poetry, whose wide-ranging body of work was well known in his time (15th century) and remained popular in the whole Hispanic literature afterwards.

The Set-Up is the classic epic hard-edged poem of an aging African American boxer who is set up to take a fall in the ring against a younger white opponent. But when he finds out the fix is in, he decides he wants to go down swinging. The Set-Up was very loosely adapted into the a film of the same name in 1949 by director Robert Wise but bore little resemblance to the original narrative. Most disappointingly for poet March, the protagonist was changed from black to white, defeating the entire point of the story in March's eyes. Fortunately the original work still packs a punch all these years later. - Summary by Ben Tucker
