Micromagnons and long-range entanglement in ferrimagnetic ground states
Marcin WieÅniak, Ankit Kumar, Idriss Hank Nkouatchoua Ngueya
While significant attention has been devoted to studying entanglement in photonic systems, solid-state spin lattices remain relatively underexplored. Motivated by this gap, we inve…

Open quantum dynamics of Josephson charge pumps
Ankit Kumar, Luis Cort, Marcin Åobejko +2
We investigate the macroscopic dynamics of Josephson charge pumps in the light of Alicki et al.'s theoretical description of the Josephson junction as an open quantum system descri…

Correlations and signaling in the Schrödinger-Newton model
Jacek Aleksander Gruca, Ankit Kumar, Ray Ganardi +3
The Schrödinger--Newton model is a semi-classical theory in which, in addition to mutual attraction, massive quantum particles interact with their own gravitational fields. While…
