Spatially inhomogeneous electron state deep in the extreme quantum limit of strontium titanate. [PDF]

Nat Commun, 2016
When an electronic system is subjected to a sufficiently strong magnetic field that the cyclotron energy is much larger than the Fermi energy, the system enters the "extreme quantum limit" (EQL) and becomes susceptible to a number of instabilities ...
