Visualization of Quantum Phenomena Wilson Ho

University of California, Irvine

The unique capabilities of the scanning tunneling microscope (STM) have enabled new opportunities for the control and investigation of matter and its transformation at the atomic and molecular scales. Some of the problems that are routinely encountered in quantum mechanics, such as particle tunneling, Brownian motion, particle in a one-dimensional box, harmonic oscillators, and molecular orbitals, can be directly visualized by combining real-space imaging, atomic and molecular manipulation, and spatially resolved spectroscopy with the STM. It has also become possible to measure quantum phenomena and excitations arising from coupling of photon radiation and tunneling electrons with the molecular electronic states and vibrational motions. Results from these experiments provide a basic, visual understanding of atoms, molecules, and nanostructures.
