Our goal as a group is to study questions of fundamental significance in condensed matter physics using state-of-the-art
experimental techniques. Our current activities include atomic scale imaging and spectroscopy of correlated electronic states,
probing and manipulating single spins, and examining properties of two-dimensional superconductors. Many of our investigations
are being carried out using high resolution scanning tunneling microscopy (STM) instruments that we have constructed over the
years in our laboratory. These are housed in PNML. In fact, a common research approach in our group is to design unique
instrumentation that enables measurements of electronic phenomena in new experimental regimes (such as measurements on finer
length scale, or at extremes of temperatures or magnetic fields). With these new experimental tools, we either search for new
phenomena by probing well-established condensed matter systems with finer accuracy or by studying new material systems, which
exhibit new properties that challenge our current understanding of electronic phenomena in solids.
