Quantum oscillation techniques comprise a set of high-precision experimental methods, such as de Haas–van Alphen and Shubnikov–de Haas measurements, that exploit periodic variations of thermodynamic or transport properties in strong magnetic fields to probe the electronic structure of solids. By tracking oscillations in magnetization, resistivity, or torque as functions of inverse magnetic field at low temperatures, these techniques yield quantitative information on Fermi surface topology, extremal orbit areas, effective masses, scattering rates, and Berry phases. They are fundamental tools in condensed matter physics for characterizing correlated electron systems, topological materials, and low-dimensional conductors with high momentum-space resolution.
When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give rise to the so-called ...
Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can ...
Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in ...
