• Insight that strange metallicity, an overarching phenomenon across quantum materials platforms,may be due to Kondo destruction even beyond heavy fermion systems [publications 1 & 7 of list].
• First MBE growth of epitaxial films of YbRh₂Si₂ and demonstration by (i) time-domain THz transmission spectroscopy that critical charge fluctuations are an integral part of the quantum criticality [8], and (ii) suppressed shot noise that quasiparticles are absent [2], advancing the understanding of strange metal physics and quantum criticality beyond the order parameter paradigm.
• Discovery of first Weyl-Kondo semimetal material [3,6], initiating (together with accompanying theoretical work) the field of correlation-driven topological semimetals.
• First electrical resistivity measurements of a quantum critical heavy fermion system (and of any metal at all) to below 1 mK, and discovery of unconventional superconductivity condensing out of an extreme strange metal state [4]. As the physics of this state is understood, this serves to advance the understanding of high-temperature cuprate superconductors, which are also strange metals.
• First observation of pristine quantum criticality in a correlated Weyl semimetal candidate material [5], suggesting that quantum criticality may nucleate correlated Weyl semimetals as emergent phase.
• Discovery of Kondo destruction associated with orbital degrees of freedom [9].
• Demonstration of Kondo destruction in quantum critical heavy fermion systems via a jump in the Hall effect [10], a key contribution to establishing a new type of quantum criticality
