    • Charge Order Driven by Fermi-Arc Instability in Bi2Sr2-xLaxCuO6+  

      Comin, R.; Frano, A.; Yee, Michael Manchun; Yoshida, Y.; Eisaki, H.; Schierle, E.; Weschke, E.; Sutarto, R.; He, F.; Soumyanarayanan, Anjan; He, Yang; Le Tacon, M.; Elfimov, I. S.; Hoffman, Jennifer Eve; Sawatzky, G. A.; Keimer, B.; Damascelli, A. (American Association for the Advancement of Science (AAAS), 2013)
      The understanding of the origin of superconductivity in cuprates has been hindered by the apparent diversity of intertwining electronic orders in these materials. We combined resonant x-ray scattering (REXS), scanning-tunneling ...
    • Dopant clustering, electronic inhomogeneity, and vortex pinning in iron-based superconductors 

      Song, Can-Li; Yin, Yi; Zech, Martin; Williams, Tess; Yee, Michael Manchun; Chen, Gen-Fu; Luo, Jian-Lin; Wang, Nan-Lin; Hudson, E. W.; Hoffman, Jennifer Eve (American Physical Society (APS), 2013)
      We use scanning tunneling microscopy to map the surface structure, nanoscale electronic inhomogeneity, and vitreous vortex phase in the hole-doped superconductor Sr0.75K0.25Fe2As2 with Tc=32 K. We find that the low-T cleaved ...
    • Fermi Surface and Pseudogap Evolution in a Cuprate Superconductor 

      He, Yang; Yin, Yi; Zech, M.; Soumyanarayanan, Anjan; Yee, Michael Manchun; Williams, T; Boyer, M. C.; Chatterjee, K.; Wise, W. D.; Zeljkovic, I; Kondo, T.; Takeuchi, T.; Ikuta, H.; Mistark, P.; Markiewicz, R. S.; Bansil, A.; Sachdev, Subir; Hudson, E. W.; Hoffman, Jennifer Eve (American Association for the Advancement of Science (AAAS), 2014)
      The unclear relationship between cuprate superconductivity and the pseudogap state remains an impediment to understanding the high transition temperature (Tc) superconducting mechanism. Here, we used magnetic field–dependent ...
    • Quantum phase transition from triangular to stripe charge order in NbSe2 

      Soumyanarayanan, Anjan; Yee, Michael Manchun; He, Yang; van Wezel, Jasper; Rahn, Dirk J.; Rossnagel, Kai; Hudson, E. W.; Norman, Michael R.; Hoffman, Jennifer Eve (Proceedings of the National Academy of Sciences, 2013)
      The competition between proximate electronic phases produces a complex phenomenology in strongly correlated systems. In particular, fluctuations associated with periodic charge or spin modulations, known as density waves, ...
    • Scanning Tunneling Spectroscopy of Topological Insulators and Cuprate Superconductors 

      Yee, Michael Manchun (2014-06-06)
      Over the past twenty-five years, condensed matter physics has been developing materials with novel electronic characteristics for a wide range of future applications. Two research directions have shown particular promise: ...
