All-optical measurement of magnetic fields for quantum gas experiments
We present an all-optical method to measure and compensate for residual
magnetic fields present in a cloud of ultracold atoms trapped in an optical
dipole trap. Our approach leverages the increased loss from the trapped atomic
sample through electromagnetically induced absorption. Modulating the
excitation laser provides coherent sidebands, resulting in {\Lambda}-type
pump-probe scheme. Scanning an additional magnetic offset field leads to pairs
of sub-natural linewidth resonances, whose positions encode the magnetic field
in all three spatial directions. Our measurement scheme is readily implemented
in a typical quantum gas experiments and has no particular hardware
requirements
The Mobility Laws of Location-Based Games
Mobility is a fundamental characteristic of human society that shapes various aspects of our everyday interactions. This pervasiveness of mobility makes it paramount to understand factors that govern human movement and how it varies across individuals. Currently, factors governing variations in personal mobility are understudied with existing research focusing on explaining the aggregate behaviour of individuals. Indeed, empirical studies have shown that the aggregate behaviour of individuals follows a truncated Levy-flight model, but little understanding exists of the laws that govern intra-individual variations in mobility resulting from transportation choices, social interactions, and exogenous factors such as location-based mobile applications. Understanding these variations is essential for improving our collective understanding of human mobility, and the factors governing it. In this article, we study the mobility laws of location-based gaming-an emerging and increasingly popular exogenous factor influencing personal mobility. We analyse the mobility changes considering the popular PokemonGO application as a representative example of location-based games and study two datasets with different reporting granularity, one captured through location-based social media, and the other through smartphone application logging. Our analysis shows that location-based games, such as PokemonGO, increase mobility-in line with previous findings-but the characteristics governing mobility remain consistent with a truncated Levy-flight model and that the increase can be explained by a larger number of short-hops, i.e., individuals explore their local neighborhoods more thoroughly instead of actively visiting new areas. Our results thus suggest that intra-individual variations resulting from location-based gaming can be captured by re-parameterization of existing mobility models.Peer reviewe
Empowering Cyber-Physical Systems with FADEX.
The proliferation of smart devices in close proximity to end users has massively increased availability of data about our surroundings and hence stimulated a plethora of new services. However, it has also increased the chances of leaking sensitive and private information about end users (e.g., geolocation data, biometric signatures). Loss of trust towards a Cloud provider can lead to a user boycott and requests for deletion of the their remotely stored personal information. While many Cloud services can handle this relatively easily, it is far more cumbersome for many smart services. In fact, the current market of smart services is composed of black-box systems dependent on tight coupling between deployed hardware and the Cloud hosted software stack leaving virtually no freedom to change service provider without considerable redeployment costs
