We reveal the existence of high-density Feshbach resonances in the collision between the ground and metastable states of ^{171}Yb and coherently produce the associated Feshbach molecules by photoassociation. The extremely small transition rate is overcome by the enhanced Franck-Condon factor of the weakly bound Feshbach molecule, allowing us to observe Rabi oscillations with long decay time between an atom pair and a molecule in an optical lattice. We also perform the precision measurement of…

Enhancement of the photoassociation of ultracold atoms via a non-resonant magnetic field

We report an effective method for enhancing the photoassociation of ultracold atoms using a non-resonant magnetic field, which enables the manipulation of the coupling between the wavefunctions of…

Observation of Feshbach resonances between alkali and closed-shell atoms

Magnetic Feshbach resonances allow control of the interactions between ultracold atoms1. They are an invaluable tool in studies of few-body and many-body physics2,3, and can be used to convert pairs…

Coherent Manipulation of Orbital Feshbach Molecules of Two-Electron Atoms

Ultracold molecules have experienced increasing attention in recent years. Compared to ultracold atoms, they possess several unique properties that make them perfect candidates for the implementation…

Magnetoassociation of a Feshbach molecule and spin-orbit interaction between the ground and electronically excited states

Ultracold Feshbach molecules are produced by magnetoassociation of fermionic Yb atoms in the ground state and an electronically excited, metastable state. A spin-orbit coupling is engineered for…

Fano effect in an ultracold atom-molecule coupled system

The Fano effect or Fano resonance with a characteristically asymmetric line shape originates from quantum interference between direct and indirect transition pathways in continuum-bound coupled…

Creation of ultracold polar ground-state RbCs molecules

This thesis reports the creation and trapping of 87RbCs molecules in the absolute ground state with a temperature of 1 uK. We build a tunable narrow-linewidth laser system at 1550 nm and 980 nm,…

Strongly Interacting Gas of Two-Electron Fermions at an Orbital Feshbach Resonance.

The experimental observation of a strongly interacting gas of ultracold two-electron fermions with an orbital degree of freedom and magnetically tunable interactions is reported, paving the way towards the realization of new quantum states of matter with strongly correlated fermion with an orbit degree offreedom.

Manipulating nanoscale atom–atom interactions with cavity QED

We theoretically explore the manipulation of interactions between excited and ground-state atoms at nanoscale separations by using cavity quantum electrodynamics (CQED). We develop an adiabatic…
