The APS Colloquium Committee has invited Laura H. Greene as the Speaker for the Wednesday, Dec. 2, 2015, APS Colloquium. She will present "High Temperature Superconductivity: Taming Serendipity" at 3 p.m. in the APS 402 Aud.
During the last decade, ptychography has emerged as an invaluable method for X-ray microscopy at synchrotron facilities that delivers quantitative images of extended specimens at diffraction limited resolution. It combines scanning microscopy with coherent diffractive imaging, probing the sample both in real and in reciprocal space and thereby creating large data sets from which iterative algorithms extract images of sample and illumination.
Researchers working to create innovative electronic systems and to understand the fundamental properties of magnetism and electronics to tackle grand challenges such as quantum computing have an new tool in their arsenal.
Using relatively low-energy X-rays, the IEX beamline at the APS will help illuminate electronic ordering and emergent phenomena in ordered materials to better understand the origins of distinct electronic properties.
The phenomenon of higher harmonic radiation from a helical undulator carrying light’s orbital angular momentum (LOAM) may be utilized as a new probe in diffraction limited light source and free-electron laser facilities. LOAM was recently demonstrated as one of the intrinsic properties not only for photon beams but also for other quantum beams such as electron and neutron beams. Last year we observed various interference patterns such as single, double, and triple spirals between two different harmonics at the BL1U Beamline of UVSOR-III.
