Experiments with single electrons in liquid helium
We have developed an apparatus which can be used to make movies showing the motion of individual electrons in liquid helium. A sound wave is used to explode an electron bubble for a fraction of a microsecond and to make it grow to have a radius of around 10 microns. While the bubble has this large size it is illuminated with a flash lamp and its position recorded. We report on a number of inter...

متن کاملObservations of the Motion of Single Electrons in Liquid Helium
We have developed an apparatus which can be used to monitor the motion of individual electrons in liquid helium. A sound wave is used to explode an electron bubble for a fraction of a microsecond. While the bubble is expanded, it is illuminated by light from a flash lamp. We describe the details of the experiment and show results obtained. In some cases, an electron is seen to follow a snakelik...
متن کاملNucleation of Bubbles on Electrons in Liquid Helium
Cavitation in liquid helium has been studied for over forty years, beginning with the work of Misener and Hebert [1] and Beams [2]. The interest in helium stemmed from the expectation that because all other elements freeze at higher temperatures, liquid helium should have exceptionally high purity. It was expected that this would greatly reduce the chance of heterogeneous nucleation, and thus e...
متن کاملQuantum computing with electrons floating on liquid helium
A quasi-two-dimensional set of electrons (1 < N < 10(9)) in vacuum, trapped in one-dimensional hydrogenic levels above a micrometer-thick film of liquid helium, is proposed as an easily manipulated strongly interacting set of quantum bits. Individual electrons are laterally confined by micrometer-sized metal pads below the helium. Information is stored in the lowest hydrogenic levels. With elec...
