Geometric heat pumping on a quantum processor
Gerónimo J. Caselli, Luis O. Manuel, Liliana Arrachea +1
Geometric heat pumping is the transfer of energy between reservoirs at equal temperature where the heat exchanged in an adiabatic cycle depends only on the driving contour in param…
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^…
