When high magnetic fields meet optical spectroscopy: probing electronic structure and interaction effects in low-dimensional semiconductor- and carbon-based structures

Dmitry Smirnov

National High Magnetic Field Laboratory
Florida State University, Tallahassee

The research in strong magnetic fields ultimately exploits very peculiar specificities of the magnetic field to obtain new information on the properties of matter. A magnetic field breaks the time reversal symmetry, localizes electrons on nm length scale, lifts degeneracy of electronic orbital and spin states, affects the electrons phase leading to a variety of quantum interference effects. It can be applied in situ in a highly controllable manner, reversibly and with perfect tunability. When high magnetic fields meet optical spectroscopy, it allows one to examine characteristic energy scales in solids associated with both elementary excitations and collective modes and resolve otherwise hidden effects and symmetries. A review of recent experimental results obtained at the National Magnet Lab is given to demonstrate the aptitude of high-field magneto-spectroscopy methods in studying the semiconductor- and carbon-based (nano)structures, and illustrate high-field spectroscopy capabilities available for the physics community.
