Luttinger Liquid in the Core of a Screw Dislocation in Helium-4
Monte carlo simulation hexagonal shaft screw crystals superfluids screw dislocation
2014/12/20
On the basis of first-principles Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp 4He crystal features a superfluid (at T→0) core. This is the first exampl...
Excited electron-bubble states in superfluid helium-4: a time-dependent density functional approach
Excited electron-bubble states time-dependent density functional approach
2010/11/19
We present a systematic study on the excited electron-bubble states in super uid 4He using a
time-dependent density functional approach. For the evolution of the 1P bubble state, two di erent functio...
Investigating metastable hcp solid helium below its melting pressure
quantum solids hcp solid helium metastability vacancy
2010/11/19
We report a first attempt to produce metastable hcp solid helium below its melting pressure. A focused sound pulse is emitted along the c-axis of a monodomain hcp helium-4 crystal starting from a stat...
Helium fine structure theory for determination of \alpha
Helium fine structure theory determination
2010/11/16
We present recent progress in the calculation of the helium fine-structure splitting of the 2^3P_J states, based on the quantum electrodynamic theory. Apart from the complete evaluation of m\alpha^7 ...

We studied the static mass-radius relation of white dwarf stars with masses greater than 0.45 M\odot. We assumed pure degenerate helium interiors at a finite temperature with luminosity-mass ratio due...
