Dynamical scheme for computing the mass parameter of a system in a medium
Agata Zdanowicz, Daniel Pęcak, Piotr Magierski +1
We present a new method for extracting a mass parameter using time-dependent density functional theory for an arbitrary physical system, provided the adiabatic limit is achievable.…
Stability conditions for bound states in antiprotonic atoms
Fredrik Parnefjord Gustafsson, Daniel Pęcak, Tomasz Sowiński
We study the stability of bound antiprotons in close proximity to the atomic nucleus. Using experimental data from X-ray spectroscopy measurements of antiprotonic atom transitions,…
Properties of a quantum vortex in neutron matter
Daniel Pęcak, Nicolas Chamel, Piotr Magierski +1
We have studied systematically microscopic properties of a quantum vortex in neutron matter at finite temperatures and densities corresponding to different layers of the inner crus…
Intercomponent correlations in attractive one-dimensional mass-imbalanced few-body mixtures
Daniel Pęcak, Tomasz Sowiński
Ground-state properties of a few attractively interacting ultra-cold atoms of different mass confined in a one-dimensional harmonic trap are studied in terms of the correlation noi…
