Critical Limitations in Cryogenic Laser Cooling of Solids: Symmetry‐Related Fluorescence Trapping and Condensation‐Induced Parasitic Heating

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.

Interfacing ultracold atoms with nanomagnetic domain walls [PDF]

, 2012
This thesis presents the first realisation of a new type of hybrid quantum device based on spintronic technology. We demonstrate an interaction between the magnetic fringing fields produced by domain walls within planar permalloy nanowires and a cloud of

Behavioral Selection of Coprophagy in an Arid‐Adapted Herbivore: Does a Compatibility–Risk Gradient Shape Selective Coprophagy?

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.

A Quantum Degenerate Mixture of $^{87}$Rb and $^{133}$Cs [PDF]

, 2011
This thesis reports the formation of a dual-species Bose-Einstein condensate of $^{87}$Rb and $^{133}$Cs in the same trapping potential. Quantum degenerate mixtures exhibit rich physics inaccessible to single species experiments and provide an ideal ...

Ab initio electronic structure and prospects for the formation of ultracold calcium–alkali-metal-atom molecular ions

New Journal of Physics, 2020
Experiments with cold ion–atom mixtures have recently opened the way for the production and application of ultracold molecular ions. Here, in a comparative study, we theoretically investigate ground and several excited electronic states and prospects for

Observation of Linear and Nonlinear Light Trapping on Topological Dislocations

Laser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.
Topological dislocations are global lattice defects found in various systems ranging from crystals to photonic lattices. This work reports the first observation at optical frequencies of linear modes with tunable localization bound to edge dislocations and their nonlinear counterparts ‐ dislocation solitons. These results reveal an intriguing interplay

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
