Interfacing carbon nanotubes and Bose-Einstein condensates of atoms

Research objectives

  • interfacing different kinds of degrees of freedom (electronic, spin, motional, etc.)
  • controlled mesoscopic transport
  • ultracold atoms as a tool for quantum measurement

Quantum galvanometer on an atom chip. A BEC is loaded into the magnetic microtrap created by classical electric currents through integrated conductors on a dielectric substrate (represented on the bottom of the chip). A suspended carbon nanotube (CNT) is also part of the electric circuit and transports the quantum current. The mechanically oscillating CNT creates a magnetic field inducing hyperfine transitions in the atoms. Atoms thus transferred to untrapped states are detected by single-atom detector.
