Observation of intrastate and interstate facilitation between Rydberg S, P and D levels
Bleuenn Bégoc, Sukhjit P. Singh, Giovanni Cichelli +2
We report experimental results on Rydberg facilitation, whereby Rydberg levels can be excited off-resonantly in the presence of a nearby Rydberg atom because of Rydberg-Rydberg int…
Universality and the thermoelectric transport properties of a double quantum dot system: Seeking for conditions that improve the thermoelectric efficiency
R. S. Cortes-Santamaria, J. A. Landazabal-Rodríguez, J. Silva-Valencia +3
Employing universal relations for the Onsager coefficients in the linear regime at the symmetric point of the single impurity Anderson model, we calculate the conditions under whic…

The ground state of spin-1 ultracold bosons trapped in a periodic one-dimensional optical superlattice is studied. The two sites of the unit cell have an energy shift between them,…
