Quantum chaos for real
Article Abstract:
Scars are concentrations of higher wave amplitude which surround classical periodic orbits and produce large variations of electric current in a tunnel diode. Scarring is produced by the quantum interference effect and causes dramatic oscillations in a robust condensed-matter device. Quantum chaos is due to extreme sensitivity of the motion of atoms to small alterations in initial conditions. Scars affect the spectra of hydrogen atoms in a magnetic field and the ionization probability of hydrogen in microwave fields.

Electrical generation and absorption of phonons in carbon nanotubes
Article Abstract:
A study is conducted to show how current directly injected into a freely suspended individual single-wall carbon nanotube can be used to excite, detect and control a specific vibrational mode of the molecule. Electrons tunneling inelastically into the nanotube cause a non-equilibrium occupation of the radial breathing mode, leading to both stimulated emission and absorption of phonons by successive electron tunneling events.
