Trend and novel challenges in spectroscopic imaging scanning tunneling microscopy for correlated electron materials research

In this presentation we would like to discuss the recent progress of the spectroscopic imaging scanning tunneling microscopy (SI-STM) and how the real- and momentum-space sensitive spectroscopic tool is evolving into a more robust quantum theoretical tool for the phase transition study of the correlated electron materials. \\[4pt] [1] Jhinhwan Lee, et al., Science 325, 1099 (2009).\\[0pt] [2] Michael J.
