Augmented projections for ptychographic imaging
Stefano Marchesini, Andre Schirotzek, Chao Yang +2
Ptychography is a popular technique to achieve diffraction limited resolution images of a two or three dimensional sample using high frame rate detectors. We introduce a relaxation…
Feynman diagrams versus Fermi-gas Feynman emulator
K. Van Houcke, F. Werner, E. Kozik +7
Precise understanding of strongly interacting fermions, from electrons in modern materials to nuclear matter, presents a major goal in modern physics. However, the theoretical desc…
Iterative Algorithms for Ptychographic Phase Retrieval
C. Yang, J. Qian, A. Schirotzek +2
Ptychography promises diffraction limited resolution without the need for high resolution lenses. To achieve high resolution one has to solve the phase problem for many partially o…
Compressive Phase Contrast Tomography
F. R. N. C. Maia, A. MacDowell, S. Marchesini +5
When x-rays penetrate soft matter, their phase changes more rapidly than their amplitude. In- terference effects visible with high brightness sources creates higher contrast, edge…
Observation of Fermi Polarons in a Tunable Fermi Liquid of Ultracold Atoms
Andre Schirotzek, Cheng-Hsun Wu, Ariel Sommer +1
We have observed Fermi polarons, dressed spin down impurities in a spin up Fermi sea of ultracold atoms. The polaron manifests itself as a narrow peak in the impurities' rf spectru…
Determination of the Superfluid Gap in Atomic Fermi Gases by Quasiparticle Spectroscopy
Andre Schirotzek, Yong-il Shin, Christian H. Schunck +1
We present majority and minority radiofrequency (RF) spectra of strongly interacting imbalanced Fermi gases of Li-6. We observed a smooth evolution in the nature of pairing correla…
