Probing the limits of optical cycling in a predissociative diatomic molecule
Physical Review Research, 2023 Molecular predissociation, the spontaneous nonradiative bond-breaking process, can limit the ability to scatter a large number of photons required to reach the ultracold regime in laser cooling.

Triatomic Photoassociation in an Ultracold Atom–Molecule Collision
The Journal of Physical Chemistry A, 2022 Ultracold collisions of neutral atoms and molecules have been of great interest since experimental advances enabled the cooling and trapping of such species. This study is a theoretical investigation of a low-energy collision between an alkali atom and a diatomic molecule, accompanied by absorption of a photon from an external electromagnetic field ...

Density Modulations of Zero Sound
Annalen der Physik, Volume 538, Issue 2, February 2026.Zero sound is a collective mode of the strongly interacting quantum gas that propagates when atomic collisions are negligible, similarly to a plasmon. This work aims at investigating the conditions under which a density modulation associated to this collective mode travels coherently through a strongly interacting Fermi gas.

Dynamics of bright solitary matter-waves [PDF]
, 2013 This thesis describes the formation of a 85Rb Bose-Einstein condensate and the subsequent creation of a bright solitary matter-wave in a quasi-one-dimensional optical waveguide, with experiments investigating the dynamics of a solitary wave in comparison

Skyrmionic Polarization Textures in Structured Dielectric Planar Media
Nanophotonics, Volume 15, Issue 3, 12 February 2026.Topological skyrmionic textures are typically associated with the structure of optical fields. This work demonstrates that they can also emerge from the optical response of structured metasurfaces. Through engineered light–matter interaction, polarization eigenstates acquire nontrivial topology, which can be mapped into the Chern‐insulator physics ...

Ultracold 88Sr2 molecules in the absolute ground state
New Journal of Physics, 2021 We report efficient all-optical creation of an ultracold gas of alkaline-earth-metal dimers, ^88 Sr _2 , in their absolute ground state. Starting with weakly bound singlet molecules formed by narrow-line photoassociation in an optical lattice, followed ...

Small Structures, Volume 7, Issue 2, February 2026.Superfluid helium nanodroplets enable ultraclean synthesis of metallic clusters and nanowires unattainable by other methods. This review surveys aberration‐corrected scanning transmission electron microscopy (STEM), electron energy loss spectroscopy (EELS)/energy‐dispersive X‐ray spectroscopy (EDX), and electron tomography to resolve their structure ...
