Realisation of a cold mixture of rubidium and caesium [PDF]
This thesis describes a new apparatus designed to study cold, ultracold, and quantum degenerate mixtures of rubidium and caesium atoms. The Rb- Cs mixture is prepared using a double magneto-optical trap (MOT) system in which a two-species pyramid MOT ...

Abstract Polaritons are quantum mechanical superpositions of photon states with elementary excitations in molecules and solids. The light–matter admixture causes a characteristic frequency‐momentum dispersion shared by all polaritons irrespective of the microscopic nature of material excitations that could entail charge, spin, lattice or orbital ...

Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

Formation of ultracold triatomic molecules by electric microwave association
A theoretical model is proposed for the formation of ultracold ground-state triatomic molecules in weakly bound energy levels. The process is driven by the electric component of a microwave field, which induces the association of an ultracold atom ...

Ultracold molecular spectroscopy: toward the narrow-line cooling of molecules
A new spectroscopic method that utilizes microwave transition of ultracold molecules is demonstrated. The narrow spectral linewidth (approximately 100 Hz) was guaranteed by preparing molecules at low temperature, and a high signal-to-noise ratio was ...

Strongly correlated ultracold bosons in an optical lattice
In this thesis, we have investigated strongly correlated bosonic gases in an optical lattice, mostly based on a bosonic version of dynamical mean field theory and its real-space extension. Emphasis is put on possible novel quantum phenomena of these many-

Coherent Microwave Control of Ultracold 23Na 40K Molecules
We demonstrate coherent microwave control of rotational and hyperfine states of trapped, ultracold, and chemically stable [superscript 23]Na [superscript 40]K molecules. Starting with all molecules in the absolute rovibrational and hyperfine ground state,

Photoinduced Two-Body Loss of Ultracold Molecules
© 2019 American Physical Society. The lifetime of nonreactive ultracold bialkali gases was conjectured to be limited by sticky collisions amplifying three-body loss.
