      abstract = {Electronic state of every solid is basically classified  into two categories according to its electrical responses:  insulator or metal. A textbook of modern solid state  physics explains that shape of a Fermi surface plays a key  role in most physical properties in metals. One of the  well-established experimental methods to detect a Fermi  surface is measurement of quantum oscillations that is a  periodic response of physical quantities with respect to  external magnetic fields. As insulators do not host Fermi  surface, it is believed that they do not exhibit any  quantum oscillations. This book presents a comprehensive  review of recent observations of quantum oscillations in  the Kondo insulators, SmB6 and YbB12, and discusses how the  observations are demonstrated by a newly proposed mechanism  where emergent charge-neutral fermions exhibit quantum  oscillations instead of bare electrons. It also focuses on  topological properties of Kondo insulators, and  demonstrates that YbB12 hosts a surface metallic conduction  owing to its non-trivial band structure. Further it  presents the experiments of specific heat and thermal  conductivity in YbB12 down to ultra-low temperature to  discuss the possible low-energy excitations from a Fermi  surface of neutral fermions. The demonstrated gapless and  itinerant fermionic excitations, that is the significant  contribution from charge neutral fermions, violates  Wiedemann-Franz law. The discoveries point out a highly  unconventional phase of quantum state--electrically  insulating but thermally metallic--realized in the bulk of  topological Kondo insulators.},
