Spin-charge separation in quantum wires

Spin-charge separation in quantum wires The electron is a fundamental building block of nature and is indivisible in isolation, yet we have performed an experiment that shows that electrons in narrow wires can appear to split apart. The experiment was performed in the University of Cambridge's...

Testing theories that go beyond the regime of applicability of Luttinger-liquid theory

We use an array of 1D wires to measure nonlinear tunnelling from the wires to a neighbouring 2D system what acts as a spectrometer for energy and momentum.

Incipient formation of an electron lattice in weakly confined quantum wires

Incipient formation of an electron lattice in weakly confined quantum wires In an electron system with a sufficiently low density that the electrons can be considered as point-like classical charges, Coulomb repulsion becomes the dominant interaction. In such a system electrons minimize their...
