The combination of stress and corrosion that can prove deadly in bridges and other structures also allows silicon to be sliced with the nanometer-scale precision required for the latest computer chips, according to simulations.
A little-known and subtle optical effect in combination with state-of-the-art pulsed laser techniques holds considerable promise as a sensitive way to study physical properties (including spin phenomena) in nanometer scale structures.
The combination of trivial and topological band insulators with a superconductor is bringing anyons—particles that behave neither according to purely Bose nor Fermi statistics—into the three-dimensional world.
The energy-momentum relationship of electrons on the surface of an ideal topological insulator forms a cone, which, when warped, can lead to unusual phenomena such as enhanced interference around defects and a magnetically ordered exotic surface.
A theoretical analysis of recent experiments suggests that a key feature of a topological quantum computer—the unusual statistics of quasiparticles in the quantum Hall effect—may finally have been observed.
By exploiting the concept of particle-hole duality, one can realize a point junction between integer and fractional quantum Hall phases, which constitutes a crucial building block towards possible applications of the quantum Hall effect.
