Chiral rotational dynamics in the molecular frame: Breaking symmetry with angular momentum
Alexander Blech, Monika Leibscher, Christiane P. Koch
Achiral molecules can be prepared in superposition states that are chiral. Here, we propose angular momentum orientation in the molecular frame to achieve the required symmetry bre…
Sympathetic rotational cooling of large trapped molecular ions
Monika Leibscher, Alexander Blech, Christiane P. Koch
We suggest a protocol for the sympathetic cooling of a molecular asymmetric top rotor co-trapped with laser-cooled atomic ions, based on resonant coupling between the molecular ion…
Enhancing the controllability of quantum systems via a static field
Ruikang Liang, Eugenio Pozzoli, Monika Leibscher +3
We provide a sufficient condition for the controllability of a bilinear closed quantum system steered by a static field and a time-varying field, based on the notion of weakly coni…
A planar rotor trapped and coupled to the vibrational modes of an ion crystal
Monika Leibscher, Ferdinand Schmidt-Kaler, Christiane P. Koch
Planar rotors can be realized by confining molecular ions or charged nanoparticles together with atomic ions in a Paul trap. We study the case of molecular ions or charged nanopart…
