Atomic Tunneling from a Scanning-Tunneling or Atomic-Force Microscope Tip: Dissipative Quantum Effects from Phonons

Atomic tunneling from a scanning-tunneling or atomic-force microscope tip: dissipative quantum effects from phonons.

We study the effects of phonons on the tunneling of an atom between two surfaces. In contrast to an atom tunneling in the bulk, the phonons couple very strongly and qualitatively change the tunneling behavior. This is the first example of Ohmic coupling from phonons for a two-state system. We propose an experiment in which an atom tunnels from the tip of an scanning-tunneling microscope, and sh...

Atomic Tunneling from a STM/AFM Tip: Dissipative Quantum Effects from Phonons

Atomic and molecular manipulation with the scanning tunneling microscope.

The prospect of manipulating matter on the atomic scale has fascinated scientists for decades. This fascination may be motivated by scientific and technological opportunities, or from a curiosity about the consequences of being able to place atoms in a particular location. Advances in scanning tunneling microscopy have made this prospect a reality; single atoms can be placed at selected positio...
