Lindbladian approach for many-qubit thermal machines: enhancing the performance with geometric heat pumping by interaction
Gerónimo J. Caselli, Luis O. Manuel, Liliana Arrachea
We present a detailed analysis of slowly driven quantum thermal machines based on interacting qubits within the framework of the Lindblad master equation. By implementing a systema…

Nontrivial entanglement passively mediated by a quenched magnetic impurity
Adelina A. Orlandini, Germán G. Blesio, Claudio J. Gazza +1
We investigate the entanglement properties of a Kondo system undergoing a transition to a state with a quenched magnetic impurity, using the density matrix renormalization group (D…

Anisotropy-driven topological quantum phase transition in magnetic impurities
Germán G. Blesio, Luis O. Manuel, Armando A. Aligia
A few years ago, a topological quantum phase transition (TQPT) has been found in Anderson and Kondo 2-channel spin-1 impurity models that include a hard-axis anisotropy term $DS_z^…
