Environmentally induced Quantum Dynamical Phase Transition in the spin swapping operation
Gonzalo Agustin Alvarez, Ernesto Pablo Danieli, Patricia Rebeca Levstein +1
Quantum Information Processing relies on coherent quantum dynamics for a precise control of its basic operations. A swapping gate in a two-spin system exchanges the degenerate stat…
Electron-Phonon interaction and electronic decoherence in molecular conductors
H. M. Pastawski, L. E. F. Foa Torres, Ernesto Medina
We perform a brief but critical review of the Landauer picture of transport that clarifies how decoherence appears in this approach. On this basis, we present different models that…
Tuning a Resonance in the Fock Space: Optimization of Phonon Emission in a Resonant Tunneling Device
L. E. F. Foa Torres, H. M. Pastawski, S. S. Makler
Phonon-assisted tunneling in a double barrier resonant tunneling device can be seen as a resonance in the electron-phonon Fock space which is tuned by the applied voltage. We show…
Resonances in Fock Space: Optimization of a SASER device
L. E. F. Foa Torres, H. M. Pastawski, S. S. Makler
We model the Fock space for the electronic resonant tunneling through a double barrier including the coherent effects of the electron-phonon interaction. The geometry is optimized…
Dynamically Driven Irreversibility in Many Body Quantum Systems: An experimental approach
Gonzalo Usaj, Horacio M. Pastawski, Patricia R. Levstein
The NMR technique allows one to create a non-equilibrium local polarization and to detect its later evolution. By a change of the sign of the effective dipolar Hamiltonian, the app…
