The spin-flip-induced quadrupole resonance in odd- exotic atoms
Fredrik P. Gustafsson, Daniel Pęcak, Tomasz Sowiński
We examine the possible existence of quadrupole resonances in exotic atoms containing odd- nuclei. We find that the spin-flip of the de-exciting exotic particle can induce a res…

Signatures of unconventional pairing in spin-imbalanced one-dimensional few-fermion systems
Daniel Pęcak, Tomasz Sowiński
A system of a few attractively interacting fermionic Li atoms in one-dimensional harmonic confinement is investigated. Non-trivial inter-particle correlations induced by intera…

Geometry-induced entanglement in a mass-imbalanced few-fermion system
Damian Włodzyński, Daniel Pęcak, Tomasz Sowiński
Many-body systems undergoing quantum phase transitions reveal substantial growth of non-classical correlations between different parties of the system. This behavior is manifested…
