Quantum Oscillations in SmB,s in a given metal provides information on the geometry of the Fermi surfaces. In this chapter, we review the theory of QOs and then examine that they were recently observed in an Kondo insulator SmB.. The discovery points to the controversy on its origin: QOs from the topological surface states or unconventional QOs from the insulating bulk.cognizant 发表于 2025-3-25 11:17:08
Book 2021modern 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事先无准备 发表于 2025-3-25 12:05:22
,Unconventional Quantum Oscillations in YbB, Kondo metallic phase. The detailed analysis suggests that the CNFs coexist and interact with conventional charged heavy fermions, adding new constraints to a successful theory of exotic excitations in KIs.符合规定 发表于 2025-3-25 16:04:18
Charge-Neutral Fermions in YbB,presence of gapless fermionic excitations with itinerant character. Interestingly, these sizable contributions lead to striking violation of Wiedemann–Frantz law, demonstrating that YbB. is electronic insulator and thermal metal. Our results expose novel charge-neutral fermions, which are potentially related to the QOs in high magnetic fields.BULLY 发表于 2025-3-25 21:52:03
