  • Coherent one-photon phase control in closed and open quantum systems: A general master equation approach 
    Pachón, Leonardo Augusto; Yu, Li; Brumer, Paul; Universidad de Antioquia, UdeA; leonardo.pachon@fisica.udea.edu.co
    Abstract: The underlying mechanisms for one photon phase control are revealed through a master equation approach. Specifically, two mechanisms are identified, one operating on the laser time scale and the other on the time scale of ...

  • Influence of Non-Markavian Dynamics in Thermal-Equilibrium Uncertainty-Relations 
    Triana, Johan F.; Pachón, Leonardo Augusto; Brumer, Paul; Universidad de Antioquia, UdeA; leonardo.pachon@fisica.udea.edu.co
    Abstract: Contrary to the conventional wisdom that deviations from standard thermodynamics originate from the strong coupling to the bath, it is shown that in quantum mechanics, these deviations originate from the uncertainty principle ...

  • Mechanisms in environmentally assisted one-photon phase control 
    Pachón, Leonardo Augusto; Brumer, Paul; Universidad de Antioquia; leonardo.pachon@fisica.udea.edu.co
    Abstract: The ability of an environment to assist in one-photon phase control relies upon entanglement between the system and bath and on the breaking of the time reversal symmetry. Here, one-photon phase control is examined ...
