Advanced Science, Volume 13, Issue 19, 2 April 2026.This study uncovers two overlooked bottlenecks in cryogenic laser cooling of solids: symmetry‐driven fluorescence trapping and water vapor condensation. We demonstrate that breaking sample symmetry enhances fluorescence escape, while condensation dominates parasitic heating below 135 K.

Small Diatomic Alkali Molecules at Ultracold Temperatures
, 2015 This thesis describes experimental work done with two of the smallest diatomic alkali molecules, 6Li2 and 23Na6Li, each formed out of its constituent atoms at ultracold temperatures.

Ecology and Evolution, Volume 16, Issue 4, April 2026.Estimated amount of each scat type consumed by Texas tortoises (Gopherus berlandieri) during 48‐h feeding trials expressed as area under the cumulative‐consumption curve (AUC; ±95% CI). Coprophagy is prevalent in Texas tortoises, and tortoises selectively choose feces along a compatibility‐risk gradient, which is evolutionarily meaningful.

An approach to spin-resolved molecular gas microscopy
New Journal of Physics, 2018 Ultracold polar molecules are an ideal platform for studying many-body physics with long-range dipolar interactions. Experiments in this field have progressed enormously, and several groups are pursuing advanced apparatus for manipulation of molecules ...

Evolutionary Applications, Volume 19, Issue 4, April 2026.ABSTRACT Habitat destruction and climate change are two primary drivers of global biodiversity loss. Many contemporary ecological preserves and preserve networks are designed to protect species and the ecological and evolutionary processes that will maintain future biodiversity.

Dynamics of ultracold polar molecules in a microwave field
New Journal of Physics, 2015 We analyze the temporal evolution of the population of ultracold polar molecules in a microwave (mw) field with a circular polarization. The molecules are in their ground $^{1}\Sigma $ state and treated as rigid rotors with a permanent dipole moment ...

Journal of Gastroenterology and Hepatology, Volume 41, Issue 4, Page 1311-1322, April 2026.To improve triage for liver fibrosis in MASLD primary care and where elastography is unavailable, a novel algorithm, FAP Index, that requires one fibrogenesis‐relevant, rapid enzyme assay, was devised and validated. FAP Index increased advanced fibrosis risk stratification accuracy by greatly reducing the frequency of indeterminate results compared to ...

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

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.

Optomechanical coupling between ultracold atoms and a membrane oscillator [PDF]
, 2014 In this thesis, I report on the realization of a hybrid optomechanical system in which ultracold atoms are coupled to a micromechanical membrane. The atoms are trapped in the intensity maxima of an optical standing wave formed by retroreflection of a ...
