Welcome to Hasan Group/Lab website!
Our lab is focused on the search and discovery (new physics) of novel quantum phases of matter. Currently, we grow and control properties of quantum
materials, perform firstprinciple theoretical calculations/predictions and develop advanced spectroscopic techniques and related tools that provide
new insights into the emergent behavior of matter. We invite you to visit our labs (Laboratory for Topo. Quantum Matter and Spectroscopy: B7B2B9B60
Jadwin Hall) in the department of physics at Princeton.
Prof. Hasan, Eugene Higgins Professor of Physics (endowed chair professorship 7/17) at Princeton University is also affiliated with Lawrence Berkeley National Laboratory in California;

Advanced AngleResolved Photoemission Spectroscopy (ARPES) and Quantum Topology 

A novel experimental approach to topological quantum phenomena: Traditionally spectroscopic methods have been used to characterize electronic behavior in quantum matter whereas initial discoveries originated from transport methods. Our works in 3D topological insulators suggest that spectroscopic methods such as ARPES can be utilized to discover novel topological quantum phenomena (Science 323, 919 (2009), Nature 452, 970 (2008), Nature 460, 1106 (2009), Science 332, 560 (2011)). Previously topological quantum phenomena (quantum Hall like effects) were being probed mainly with transport methods pioneered by von Klitzing (1980). Following our demonstration of application of spinARPES, there are worldwide efforts to apply this technique and its derivatives to probe and study novel topological quantum phenomena in condensed matter systems.
