Strongly correlated metals comprise an enduring puzzle at the heart of condensed matter physics. Commonly a highly renormalized heavy Fermi liquid occurs below small coherence scale, while higher temperatures broad incoherent regime pertains in which quasi-particle description fails. Despite ubiquity this phenomenology, strong correlations and quantum fluctuations make it challenging to study. The Sachdev-Ye-Kitaev(SYK) model describes $0+1$D cluster with random all-to-all...

The canonical understanding of quantum oscillation in metals is challenged by the observation de Haas-van Alphen effect an insulator, SmB_{6} [Tan et al, Science 349, 287 (2015)]. Based on a two-band model with inverted band structure, we show that periodically narrowing hybridization gap magnetic fields can induce low-energy density states bulk, which observable provided activation energy small and comparable to Landau level spacing. Its temperature dependence strongly deviates from...
