Tunneling and Evaporation from the Electron Liquid Trapped at a Helium Surface
Tunneling and evaporation from a well characterized many body quantum mechanical system is an important and intriguing experimental and theoretical problem. 2-D electrons trapped at the bulk helium vacuum interface is such a system. There are strong coulomb correlations among the electrons whose density may be easily varied over a wide range. The strong correlations are manifested by a crystalization at sufficiently high densities and low temperatures.(1) Escape from such a system can be initiated by the application of external fields which are roughly a hundred volts per cm. In addition, the system is extraordinarily clean and homogeneous, i.e. free of defects, local field hot spots, impurities, etc.
