Local Quantum Cooling for Large Fermi Systems with Pairing
J. E. Alba-Arroyo, Daniel Pęcak, Michael McNeil Forbes +1
We present a framework for local quantum cooling that can be efficiently applied to large-scale Fermi systems. The method introduces local Hermitian operators as a cooling potentia…
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,…
Real-time antiproton annihilation vertexing with sub-micron resolution
M. Berghold, D. Orsucci, F. Guatieri +63
The primary goal of the AEgIS experiment is to precisely measure the free fall of antihydrogen within Earth's gravitational field. To this end, a cold ~50K antihydrogen beam has to…
Quantum vortices in fermionic superfluids: from ultracold atoms to neutron stars
Piotr Magierski, Andrea Barresi, Andrzej Makowski +2
Superfluid dilute neutron matter and ultracold gas, close to the unitary regime, exhibit several similarities. Therefore, to a certain extent, fermionic ultracold gases may serve a…
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…
Few strongly interacting ultracold fermions in one-dimensional traps of different shapes
Daniel Pęcak, Tomasz Sowiński
The ground-state properties of a few spin-1/2 fermions with different masses and interacting via short-range contact forces are studied within an exact diagonalization approach. It…
