Emergence of states in a quantum impurity model
Moallison F. Cavalcante, Marcus V. S. Bonança, Eduardo Miranda +1
In the present work, we demonstrate the emergence of states in the long-time response of a locally perturbed many-body quantum impurity model. The emergence of the double-qubit…

Nano-welding of quantum spin- chains at minimal dissipation
Moallison F. Cavalcante, Marcus V. S. Bonança, Eduardo Miranda +1
We consider the optimal control of switching on a coupling term between two quantum many-body systems. Specifically, we (i) quantify the energetic cost of establishing a weak junct…
