Description:
Helium nanodroplets are considered ideal model systems to explore quantum hydrodynamics in self-contained, isolated superfluids. However, exploring the dynamic properties of individual droplets is experimentally challenging. In this work, we used single-shot femtosecond x-ray coherent diffractive imaging to investigate the rotation of single, isolated superfluid helium-4 droplets containing ~10(8) to 10(11) atoms. The formation of quantum vortex lattices inside the droplets is confirmed by observing characteristic Bragg patterns from xenon clusters trapped in the vortex cores. The vortex densities are up to five orders of magnitude larger than those observed in bulk liquid helium. The droplets exhibit large centrifugal deformations but retain axially symmetric shapes at angular velocities well beyond the stability range of viscous classical droplets.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gomez, Luis F -- Ferguson, Ken R -- Cryan, James P -- Bacellar, Camila -- Tanyag, Rico Mayro P -- Jones, Curtis -- Schorb, Sebastian -- Anielski, Denis -- Belkacem, Ali -- Bernando, Charles -- Boll, Rebecca -- Bozek, John -- Carron, Sebastian -- Chen, Gang -- Delmas, Tjark -- Englert, Lars -- Epp, Sascha W -- Erk, Benjamin -- Foucar, Lutz -- Hartmann, Robert -- Hexemer, Alexander -- Huth, Martin -- Kwok, Justin -- Leone, Stephen R -- Ma, Jonathan H S -- Maia, Filipe R N C -- Malmerberg, Erik -- Marchesini, Stefano -- Neumark, Daniel M -- Poon, Billy -- Prell, James -- Rolles, Daniel -- Rudek, Benedikt -- Rudenko, Artem -- Seifrid, Martin -- Siefermann, Katrin R -- Sturm, Felix P -- Swiggers, Michele -- Ullrich, Joachim -- Weise, Fabian -- Zwart, Petrus -- Bostedt, Christoph -- Gessner, Oliver -- Vilesov, Andrey F -- New York, N.Y. -- Science. 2014 Aug 22;345(6199):906-9. doi: 10.1126/science.1252395.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Southern California (USC), Los Angeles, CA 90089, USA. ; Linac Coherent Light Source (LCLS), SLAC National Accelerator Laboratory, 2575 Sand Hill Road, Menlo Park, CA 94025, USA. ; Ultrafast X-ray Science Laboratory, Chemical Sciences Division, Lawrence Berkeley National Laboratory (LBNL), Berkeley, CA 94720, USA. ; Ultrafast X-ray Science Laboratory, Chemical Sciences Division, Lawrence Berkeley National Laboratory (LBNL), Berkeley, CA 94720, USA.
