Insulator or a metal? When a metal is cooled to low temperatures and placed in an external magnetic field, its resistivity may oscillate as the magnitude of the field is varied. Seeing these so-called quantum oscillations in an insulating material would be very unusual. Xiang et al. report such findings in the insulator ytterbium dodecaboride (YbB12) (see the Perspective by Ong). In addition to oscillations in resistivity, the authors observed oscillations in the magnetic torque. The results… 

Quantum oscillations in an insulator

Xiang et al. (3) report torque and magnetoresistance experiments on the “Kondo insulator” YbB12, which becomes a bulk insulator below 10 K, and present a persuasive case for a bulk origin for the quantum oscillations detected in the resistance.

Unconventional thermal metallic state of charge-neutral fermions in an insulator

Quantum oscillations in transport and thermodynamic parameters at high magnetic fields are an unambiguous signature of the Fermi surface, the defining characteristic of a metal. Recent observations

Unusual high-field metal in a Kondo insulator

Strong electronic interactions in condensed-matter systems often lead to unusual quantum phases. One such phase occurs in the Kondo insulator YbB12, the insulating state of which exhibits phenomena

Quantum oscillations in interaction-driven insulators

In recent years it has become understood that quantum oscillations of the magnetization as a function of magnetic field, long recognized as phenomena intrinsic to metals, can also manifest in

Quantum oscillations of magnetization in interaction-driven insulators

In recent years it has become understood that quantum oscillations of the magnetization as a function of magnetic field, long recognized as phenomena intrinsic to metals, can also manifest in

Quantum oscillations in the magnetization and density of states of insulators.

The observation of [Formula: see text]-periodic behavior in Kondo insulators and semiconductor quantum wells challenges the conventional wisdom that quantum oscillations (QOs) necessarily arise from

Quantum oscillations in correlated insulators of a moir\'e superlattice

Quantum oscillations (QOs) are ubiquitous in metal due to the Landau quantization of cyclotron motion in magnetic field, while they are generally absent in an insulator. Here, we report an

Hall Anomaly, Quantum Oscillations and Possible Lifshitz Transitions in Kondo Insulator YbB12 : Evidence for Unconventional Charge Transport

In correlated electronic systems, strong interactions and the interplay between different degrees of freedom may give rise to anomalous charge transport properties, which can be tuned by exter-nal

Enhanced quantum oscillations in Kondo insulators

Quantum oscillations have long been regarded as the manifestation of the Fermi surface in metals. However, they were recently observed in Kondo insulators. We examine the Kondo screening due to

Charge-neutral fermions and magnetic field-driven instability in insulating YbIr3Si7

Kondo lattice materials, where localized magnetic moments couple to itinerant electrons, provide a very rich backdrop for strong electron correlations. They are known to realize many exotic



Unconventional Fermi surface in an insulating state

Probing the insulating state of SmB6 When a metal is subjected to a strong magnetic field, its electrons start rearranging into new energy levels, causing its electronic properties to oscillate as a

Quantum oscillations in insulators with neutral Fermi surfaces

We develop a theory of quantum oscillations in insulators with an emergent fermi sea of neutral fermions minimally coupled to an emergent $U(1)$ gauge field. As pointed out by Motrunich (Phys. Rev. B

Majorana Fermi Sea in Insulating SmB6: A proposal and a Theory of Quantum Oscillations in Kondo Insulators

In an exciting development, SmB6, a Kondo insulator has been shown to exhibit bulk quantum oscillations. We propose that SmB6 is a bulk scalar Majorana Fermi Liquid} (MFL) with a finite gap for

Quantum Oscillation in Narrow-Gap Topological Insulators.

A two-band model with inverted band structure is shown that the periodically narrowing hybridization gap in magnetic fields can induce the oscillation of low-energy density of states in the bulk, which is observable provided that the activation energy is small and comparable to the Landau level spacing.

Skyrme Insulators: Insulators at the Brink of Superconductivity.

This work argues that the loss of topological protection in a superconductor gives rise to an insulating ground state, and introduces the concept of a Skyrme insulator to describe the coherent dielectric state that results from the topological failure of superflow carried by a complex-vector order parameter.

Chemical potential asymmetry and quantum oscillations in insulators

We present a theory of quantum oscillations in insulators that are particle-hole symmetric and non-topological but with arbitrary band dispersion, at both zero and non-zero temperature. At

Two-dimensional Fermi surfaces in Kondo insulator SmB6

The electronic structure of SmB6 in high magnetic fields is traced and it is found that it does indeed have two-dimensional surface states, and this material is confirmed to be a topological insulator.

Quantum Oscillations without a Fermi Surface and the Anomalous de Haas-van Alphen Effect.

It is shown that, in contrast to this canonical situation, there can be quantum oscillations even for band insulators of certain types, showing strong deviations from LK theory.

How Are Heavy and Itinerant Electrons Born in a Dilute Kondo Alloy

We report a continuous evolution of Fermi surface properties with temperature in a dilute Kondo alloy of Ce 0.02 La 0.98 Ru 2 Si 2 via measurements of the de Haas–van Alphen (dHvA) effect. The

Topological surface state in the Kondo insulator samarium hexaboride.

Thickness-dependent transport measurements on doped SmB6 are reported, and it is shown that magnetic and non-magnetic doping results in contrasting behaviour that supports the conclusion that SmB 6 shows virtually no residual bulk conductivity.
