In Condensed Matter Physics
Within a solid the mass in the cyclotron frequency equation above is replaced with the effective mass tensor . Cyclotron resonance is therefore a useful technique to measure effective mass and Fermi surface cross-section in solids. In a sufficiently high magnetic field at low temperature in a relatively pure material
where is the carrier scattering lifetime, is Boltzmann's constant and is temperature. When these conditions are satisfied, an electron will complete its cyclotron orbit without engaging in a collision, at which point it is said to be in a well-defined Landau level.

Famous quotes containing the words condensed, matter and/or physics:
“If you read only the best, you will have no need of reading the other books, because the latter are nothing but a rehash of the best and the oldest. To read Shakespeare, Plato, Dante, Milton, Spenser, Chaucer, and their compeers in prose, is to read in condensed form what all others have diluted.”
—Anna C. Brackett (1836–1911)
“No matter what our achievements might be, we think well of ourselves only in rare moments. We need people to bear witness against our inner judge, who keeps book on our shortcomings and transgressions. We need people to convince us that we are not as bad as we think we are.”
—Eric Hoffer (1902–1983)
“... it is as true in morals as in physics that all force is imperishable; therefore the consequences of a human action never cease.”
—Tennessee Claflin (1846–1923)
