Fermi Surfaces and Where to Find Them: Quantum Oscillations in Kondo Insulators and High-Temperature Superconductors
… of SmB₆ and YbB₁₂, two strongly-correlated Kondo insulators. We also present magnetic and transport measurements of underdoped YBa₂Cu₃O₆₊ₓ, a high-temperature superconductor, that prompt us to reinterpret the quantum oscillations previously associated with the non-superconducting normal …

SPIN-ORBIT COUPLING IN STRONGLY CORRELATED SYSTEMS
… the first case, impurity states in topological Kondo insulators are studied. Both in-gap and deep-bound impurity states are explicitly examined. The in-gap impurity states have properties similar to those of the topological surface states. It can explain some anomalous properties observed in …

Unconventional Fermi surface in insulating SmB6 and superconducting YBa2Cu3O6+x probed by high magnetic fields
… systems. SmB$_6$ is a classic example of Kondo insulators whose insulating behaviour arises due to strong correlation between the itinerant $d$-electrons and localised $f$-electrons. The peculiar resistivity plateau onsets below 4 K has been a decades-long puzzle whose origin has been …

High magnetic field quantum oscillation study of Fermi surfaces in bulk unconventional insulators
… has therefore existed between conductors and insulators, where charge carriers' ability to roam freely separates the two phases of matter. However, even this seemingly immutable distinction has recently begun to blur. The recent discovery of a bulk Fermi surface in the Kondo insulator SmB6 has …

High magnetic field study of strongly correlated electron systems
… and magnetisation measurements on the Kondo insulator samarium hexaboride. Shubnikov-de Haas oscillations observed in the former further our understanding of the nature of the normal states of these high temperature superconductors, crucial to unravel the origin of unconventional …
