On-chip optical lattice for cold atom experiments. [PDF]
Optics Letters, 2015 An atom-chip-based integrated optical lattice system for cold and ultracold atom applications is presented. The retroreflection optics necessary for forming the lattice are bonded directly to the atom chip, enabling a compact and robust on-chip optical ...

High resolution imaging and optical control of Bose-Einstein condensates in an atom chip magnetic trap [PDF]
, 2012 A high-resolution projection and imaging system for ultracold atoms is implemented using a compound silicon and glass atom chip. The atom chip is metalized to enable magnetic trapping while glass regions enable high numerical aperture optical access to ...

Silicon nitride waveguide polarization rotator and polarization beam splitter for chip-scale atomic systems [PDF]
APL Photonics, 2022 The design, fabrication, and characterization of a silicon nitride waveguide polarization rotator and polarization beam splitter that operate with a polarization extinction ratio (PER) of ∼30 dB at the rubidium atomic transition of 780 nm wavelength are demonstrated.

Mechanisms for the emergence of Gaussian correlations
SciPost Physics, 2022 We comprehensively investigate two distinct mechanisms leading to memory loss of non-Gaussian correlations after switching off the interactions in an isolated quantum system undergoing out-of-equilibrium dynamics.

Positioning performance of chip-scale atomic clock GNSS augmentation systems [PDF]
2016 8th ESA Workshop on Satellite Navigation Technologies and European Workshop on GNSS Signals and Signal Processing (NAVITEC), 2016 Current GNSS (Global Navigation Satellite System) receivers include an internal quartz oscillator, such as TCXO (Temperature Compensated Crystal Oscillator) or similar, limited by its frequency stability and a poor accuracy, being one of the main sources of uncertainty in the navigation solution (also multipath and ionosphere effects are an important ...

Thermally pumped on-chip maser [PDF]
Physical review B, 2020 We present a theoretical model of an on-chip three-level maser in a superconducting circuit based on a single artificial atom and pumped by a temperature gradient between thermal baths coupled to different interlevel transitions.

Matter-wave beam splitter on an atom chip for a portable atom interferometer [PDF]
Applied physics B, 2016 We constructed a matter-wave beam splitter on an atom chip using a 87Rb Bose–Einstein condensate. Using radio-frequency-induced double-well potentials, we were able to coherently split a BEC into two clouds separated by distances ranging from 2.8 to 57 ...
