NbN-based Josephson junctions grown by plasma-assisted molecular beam epitaxy
We focused on the growth of δ-NbN due to its high Tc that can be interesting for devices like JJs. The structures grown and analyzed in this work are presented in Fig. 1. First, we investigated the growth of 30-50 nm δ-NbN layers on bulk…

Protecting gauge symmetries in the dynamics of SU(3) lattice gauge theories
A suitable framework to study dynamics: LSH framework
As mentioned in the Introduction, we focus on a particular framework, namely the LSH framework developed for SU(2)4 and SU(3)108,109 gauge theories in 1 + 1 dimensions. The SU(2) framework has…
