We present a review of the properties of negative ions that are produced when electrons are inserted into superfluid helium-4. It is convenient to divide the ions into two groups. The first is the ion usually referred to as the “normal electron bub

Studying the kinetics of phase transformation and phase boundary propagation during initial lithiation of silicon electrodes in lithium ion batteries is relevant to understanding their performance. Such studies are usually challenging due to the diff

Being one of the major incentives in advancing technologies, characterizing the phase transformation in materials is yet far from reaching a fully comprehended subject. Understanding the mechanics, thermodynamics, and kinetics of the phase transforma

Exotic ions are negatively charged objects which have been detected in superfluid helium-4 at temperatures in the vicinity of 1 K. Mobility experiments in several different labs have revealed the existence of at least 18 such objects. These ions have
We describe a method for dark matter detection based on the evaporation of helium atoms from a cold surface and their subsequent detection using field ionization. When a dark matter particle scatters off a nucleus of the target material, elementary e

In 2004 Kim and Chan performed a torsional oscillator measurement of the rotational inertia of solid helium-4. They found frequency changes which were interpreted in terms of a non-classical rotational inertia, that is a partial superfluidity or "sup

Recent experiments have shown that the shear modulus of solid helium undergoes a large temperature variation in the range 20 to 200 mK, possibly due to changes in the pinning of dislocations. In this note we report on computer simulations of the elas

Given the running controversies on the interpretation of supersolidity, it appears important to measure more accurately what are the properties of helium 4 crystals in the absence of disorder. We recall how to prepare single crystals with no or very

We have performed computer simulations of the motion of electron bubbles through superfluid helium. The helium is modeled through the use of a modified version of the Gross-Pitaevskii equation. We find that by the time the bubble reaches the velocity

In this note we report on simple estimates of the properties of metastable solid helium that is at a pressure below the normal melting pressure. We calculate the nucleation rate for formation of the liquid phase and estimate the “spinodal” pressu
