Resistance oscillation reveals the electronic structure of YbB 12. Researchers have discovered quantum oscillations of electrical resistivity in an insulator for the first time. The new discovery, ...

Quantum-oscillation experiments in YBCO (refs 2, 3, 4), when analysed using the conventional Onsager–Lifshitz picture 9,10,11, indicate small Fermi pockets, each with an area covering ...

"We were able to keep track of the Lifshitz transition by applying pressure and measuring the quantum oscillations as the pressure was increased," corresponding author Hideaki Sakai says.

The researchers attributed this to quantum mechanics resonance of the electron oscillations. About 60 years ago, Soviet physicist Ilya M. Lifshitz predicted mechanical softening, which is known as ...
