Green's Function Approach to Josephson Dot Dynamics and Application to Quantum Mpemba Effects
Kateryna Zatsarynna, Andrea Nava, Reinhold Egger +1
We develop a Green's function approach for the nonequilibrium dynamics of multi-level quantum dots coupled to multiple fermionic reservoirs in the presence of a bosonic environment…

Coulomb impurities in graphene driven by fast ions
Saparboy Rakhmanov, Reinhold Egger, Doniyor Jumanazarov +1
We provide a theoretical model for electronic transitions in a two-dimensional (2D) artificial atom in a graphene monolayer. The artificial atom is due to the presence of a charged…

Many-body quantum dynamics of spin-orbit coupled Andreev states in a Zeeman field
Kateryna Zatsarynna, Andrea Nava, Alex Zazunov +1
We provide a theoretical framework to describe the quantum many-body dynamics of Andreev states in Josephson junctions with spin-orbit coupling and a magnetic Zeeman field. In such…
