Correlated States in Quantum Dot Clusters Coupled to a Common Superconductor

Martin Žonda, Jakub Rękas, Tobiáš Poláček +3

We study an effective model of regular quantum dot clusters coupled to a common superconductor. By applying a canonical transformation, we map the system onto a particle-number-con…

Spin subdiffusion in perturbed infinite-U Hubbard chain

Jakub Rękas, Marcin Mierzejewski, Zala Lenarčič +1

The -model represents the Hubbard model in the limit and is one of the basic models of strongly correlated electrons. On a one-dimensional chain, the model is int…
