Cooper pair charge Kondo effect in a hybrid quantum dot - superconductor device
Luca Gonfiantini, Lorenzo Maffi, Michele Burrello
We consider a tunable hybrid device composed of four quantum dots and a floating superconducting island -- the so-called poor man's tetron -- close to its effective particle-hole s…
Cooper quartets and fractional vortices in frustrated Josephson junction dice arrays
Erik Lennart Weerda, Olav F. Syljuåsen, Matteo Rizzi +1
Superconductivity mediated by Cooper quartets of charge 4e is a phenomenon of key importance for both the understanding of certain exotic superconductors and the engineering of qua…
When the center matters: color screening and gluelumps in dihedral lattice gauge theories
Pavel P. Popov, Edoardo Ballini, Alberto Bottarelli +4
Confinement is one of the hallmarks of quantum chromodynamics (QCD), but its first-principles characterization remains elusive. We show that discrete non-Abelian lattice gauge theo…
The poor man's Majorana tetron
Maximilian Nitsch, Lorenzo Maffi, Virgil V. Baran +4
The Majorana tetron is a prototypical topological qubit stemming from the ground state degeneracy of a superconducting island hosting four Majorana modes. This degeneracy manifests…
Majorana modes in quantum dots coupled via a floating superconducting island
R. Seoane Souto, V. V. Baran, M. Nitsch +4
Majorana modes can be engineered in arrays where quantum dots (QDs) are coupled via grounded superconductors, effectively realizing an artificial Kitaev chain. Minimal Kitaev chain…
Engineering a Josephson junction chain for the simulation of the clock model
Matteo M. Wauters, Lorenzo Maffi, Michele Burrello
The continuous improvement of fabrication techniques and high-quality semiconductor-superconductor interfaces allowed for unprecedented tunability of Josephson junction arrays (JJA…
