SUMMARY:Workshop / Seminar:Department Colloquium | High-Temperature Superconductivity – Insights from Einstein’s Electrons
DESCRIPTION:Complex phenomena in solids remain a central theme of 21st-century physics. Angle-resolved photoemission spectroscopy (ARPES)\, based on Einstein’s photoelectric effect\, has emerged as a leading tool for exploring this frontier\, providing direct\, momentum-resolved access to the electronic structure—the “DNA” of quantum materials. Its impact spans cuprate superconductors\, topological systems\, and two-dimensional materials\, where it has both tested theoretical ideas and revealed unexpected behavior. \n\nIn this talk\, I will discuss both the progress and remaining challenges in understanding cuprate high-temperature superconductors through the lens of ARPES. From testing theoretical ideas and uncovering unexpected phenomena to resolving long-standing puzzles and benchmarking models\, systematic ARPES studies point toward a pathway for achieving high-temperature superconductivity. \n\nIn the poorly screened regime near correlation-driven insulating states\, the interplay between strong electron–electron and electron–phonon interactions could enhance pairing  strength while suppressing structural instabilities. At the same time\, this environment fosters competing orders and fluctuations\, giving rise to the rich and complex phenomenology characteristic of these unconventional superconductors.\n\nA.

An experimental condensed matter physicist\, he is renowned for establishing angle-resolved photoemission spectroscopy (ARPES) as a central tool for probing the electronic structure of quantum materials\, transforming the field. His contributions have been recognized by the Department of Energy E.O. Lawrence Award\, the APS Oliver E. Buckley Prize\, and the International Kamerlingh Onnes Prize\, and elections to the U.S. National Academy of Sciences\, the American Academy of Arts and Sciences\, and the Royal Society. A dedicated mentor\, he has trained numerous  worldwide. He has held major leadership roles at Stanford and SLAC and contributed to science policy through DOE BESAC and international advisory boards.
