Hot spacetimes for cold atoms [PDF]
Journal of High Energy Physics, 2008 Building on our earlier work and that of Son, we construct string theory duals of non-relativistic critical phenomena at finite temperature and density. Concretely, we find black hole solutions of type IIB supergravity whose asymptotic geometries realize the Schroedinger group as isometries.

Bose-Hubbard model of cold atoms to higher orders [PDF]
, 2022 The aim of this work is to study the dynamics of cold atoms trapped in a one-dimensional periodic lattice generated by an optical potential. Such a system is described by a standard model in condensed matter, namely the so-called Bose-Hubbard model ...

Atom guiding in free-space light beams and photonic crystal fibres [PDF]
, 2007 In this thesis I describe experimental work and present data on the guiding of Rubidium atoms along free-space propagating light beams as well as within hollow core glass fibres, namely photonic crystal fibres.

Simultaneous deceleration of atoms and molecules in a supersonic beam
New Journal of Physics, 2015 A unique property of Zeeman effect based manipulation of paramagnetic particle’s motion is the ability to control velocities of both atoms and molecules.

Mean-Field Description of Cooperative Scattering by Atomic Clouds
Atoms, 2023 We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by a uniform laser, including the initial build up, the ...

Quantum simulation of non-trivial topology
New Journal of Physics, 2015 We propose several designs to simulate quantum many-body systems in manifolds with a non-trivial topology. The key idea is to create a synthetic lattice combining real-space and internal degrees of freedom via a suitable use of induced hoppings.

The separation between mRNA‐ends is more variable than expected
FEBS Open BioEffective circularization of mRNA molecules is a key step for the efficient initiation of translation. Research has shown that the intrinsic separation of the ends of mRNA molecules is rather small, suggesting that intramolecular arrangements could ...

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

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