Electrons in Superfluid Helium-4
We review the current status of theory and experiment concerning electrons in superfluid helium-4 with an emphasis on some of the unsolved problems. Although calculations of the bubble structure have been confirmed in detail by measurements of the optical absorption spectrum, the energy of interaction of a bubble with a vortex is not understood. We discuss the theory behind a proposed experimen...
متن کاملSuperfluid helium quantum interference devices
We present an overview of recent developments related to superfluid helium quantum interference devices (SHeQUIDs). We discuss the physics of two reservoirs of superfluid helium coupled together and describe the quantum oscillations that result from varying the coupling strength. We explain the principles behind SHeQUIDs that can be built based on these oscillations and review some techniques a...
متن کاملNovel methods to create multielectron bubbles in superfluid helium.
An equilibrium multielectron bubble (MEB) in liquid helium is a fascinating object with a spherical two-dimensional electron gas on its surface. We discuss two ways in which they have been created. For MEBs that have been observed in the dome of a cylindrical cell with an unexpectedly short lifetime, we show analytically why these MEBs can discharge by tunneling. Using a novel method, MEBs have...
متن کاملStabilization of Multi-electron Bubbles in Superfluid Helium
Multielectron bubbles (MEBs) in liquid helium were first observed in the late 1970s, but their properties have never been explored experimentally due to their short lifetimes and the difficulty to localize them. We report the observation of longlived MEBs in a novel cell filled with superfluid helium at static negative pressures. MEBs were extracted from the electron filled vapor sheath of a he...
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...
