Effect of interactions on quantum oscillations in Kondo insulators

Hybridization-gap insulators provide a mean-field model for studying quantum oscillations in Kondo insulators. Our recent work [1] has revealed that density of states (SdH) and magnetization oscillations (dHvA) in such systems exhibit different frequencies and different field and temperature-dependent amplitudes, in marked contrast with metals. Kondo insulators are, however, strongly correlated systems where interaction effects cannot be a priori ignored. In this work, we generalize the periodic Anderson model with Sachdev-Ye-Kitaev SYK-like interactions for the f-electrons. We study the fate of quantum oscillations in Kondo insulators in this solvable limit.
