Topological Quantum Science & Engineering

Topological Quantum Science and Engineering: Hasan lab helped launch the field of Topological Insulators by directly detecting the novel surface states and thoroughly demonstrating their unusual topological properties using advanced spin-sensitive spectroscopic techniques (50,000+ citations). Subsequently, Hasan group has theoretically and experimentally discovered many novel classes of topological matter and topological phase transitions including Topological Magnets (via the demonstration of Chern gap in 2012) using novel instrumentations and innovative methods and introduced designed discovery methods. The field expanded to include topological semimetals, notably Weyl Semimetals, whose states mimic massless fermions considered in quantum field theory. In 2015 Hasan group observed the emergent Weyl fermions and novel topological Fermi arc surface states in several topological semimetals he and his team theoretically predicted in arsenide and other materials. His Weyl fermion work is based on his and his team's theoretical predictions in several spin-orbit materials. Subsequently, he has theoretically and experimentally discovered many novel classes of magnetic topological semimetals. He has also made groundbreaking contributions (theoretical and experimental) in the subfields of topological phase transitions, topological magnets in 2D and 3D, topological nodal-line and drumhead metals, topological magnetic semimetals, topological chiral crystals, topological Hopf link semimetals, topological superconductors, Helicoid-arc quantum states and Kagome magnets and materials, Chern magnets and charge-ordered Kagome superconductors enabled by innovative applications and development of experimental methods. He identified room temperature topological materials. A vast majority of his experimental discoveries are based on his and his team's theoretical predictions of topological materials. These materials are broadly important for future device applications with higher energy efficiency, as quantum information science platforms, and for exploring new emergent or many-body quantum physics. He has also contributed to the conceptual design and theoretical development of some of these topics and written several comprehensive review articles by invitation. The methodologies introduced by him to explore and discover topological materials and phenomena are being used by others world-wide to further advance the field and led to new discoveries. His experiments and methods have been seminal in giving rise to the field of "Topological Quantum Matter" with more than 90,000 citations (over 250 publications with h-factor 105+), which is now growing vigorously at the nexus of condensed matter physics, materials engineering, nano-science, device physics & quantum engineering, chemistry and relativistic quantum field theory as evidenced in all citation tracks.
