A cold strontium Rydberg gas [PDF]

, 2011
Cold gases of Rydberg atoms are an ideal system in which to study the novel effects of strong interatomic interactions. This thesis describes the design and construction of the world's first experiment to study Rydberg states in a cold gas of an alkaline

Fabrication of crystals from single metal atoms [PDF]

, 2014
Metal nanocrystals offer new concepts for the design of nanodevices with a range of potential applications. Currently the formation of metal nanocrystals cannot be controlled at the level of individual atoms. Here we describe a new general method for the

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Observation of effects of inter-atomic interaction on Autler–Townes splitting in cold Rydberg atoms

New Journal of Physics
We demonstrate the effect of inter-atomic interaction in highly excited Rydberg atoms via Autler–Townes (AT) splitting in cold atoms. We measure the AT splitting of the $\{5S_{1/2}, F = 2\} \rightarrow \{5P_{3/2}, F^{^{\prime}} = 3\}$ transition of ^87 ...

Self-Organization in Cold Atoms Mediated by Diffractive Coupling

Atoms, 2021
This article discusses self-organization in cold atoms via light-mediated interactions induced by feedback from a single retro-reflecting mirror. Diffractive dephasing between the pump beam and the spontaneous sidebands selects the lattice period ...

Sympathetic cooling and self-oscillations in a hybrid atom-membrane system [PDF]

, 2016
Hybrid systems combining mechanical oscillators and ultracold atoms provide novel opportunities for cooling, detection and quantum control of mechanical motion with applications in precision sensing, quantum-level signal transduction and for ...

Production of Cold Positronium Atoms

Acta Physica Polonica A, 2008
. In order to study antimatter physical properties (CPT(charge, parity, time) invariance and principle of equivalence test) it is nec-essary to keep this system at the lowest possible (sub-kelvin) temperatures.This requires the generation of a suitable °ux of cold Ps atoms in a vacuum,a non-trivial requirement at the light of the present experimental ...

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Subradiance and radiation trapping in cold atoms

New Journal of Physics, 2018
We experimentally and numerically study the temporal dynamics of light scattered by large clouds of cold atoms after the exciting laser is switched off, in the low intensity (linear-optics) regime. Radiation trapping due to multiple scattering as well as
