Local Quantum Cooling for Large Fermi Systems with Pairing
J. E. Alba-Arroyo, Daniel PÄcak, 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 PÄcak, 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 PÄcak, Tomasz SowiÅski
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,…
