Search for Majorana Bound States in Short Chains of Proxmitised Quantum Dots
Bogdan R. Bułka, Karol I. Wysokiński
Majorana zero modes (MZM) appearing at the ends of artificially created one-dimensional p-wave superconductors have been intensively studied recently both theoretically and experim…

Beyond Hubbard: the role of correlated hopping interaction in superconductors and quantum dot devices
Karol I. Wysokiński, Marcin M. Wysokiński
We investigate the role of strong Coulomb interactions beyond the standard Hubbard model in two distinct physical contexts. First, we analyze the superconducting phase transition o…

Interplay of spin orbit interaction and Andreev reflection in proximized quantum dots
Bogdan R. Bułka, Tadeusz Domański, Karol I. Wysokiński
We investigate a hybrid device consisting of two quantum dots placed between a BCS superconductor and a semiconductor with a strong spin-orbit interaction. Assuming charge tunnelin…
