The sensitivity of interferometers based on freely falling atoms depends on the time atoms spend in the interferometer, i. e. the interrogation time. In a terrestrial experiment, this time is limited by the available free ...

Quantensensoren auf Basis ultrakalter Gase bieten auf Grund ihrer Genauigkeit und Stabilität große Vorteile gegenüber klassischen Sensoren in der Inertialsensorik, fundamentalen Physik, Metrologie und Geodäsie. Die ...

This thesis investigates the influence of laser relative intensity noise on the phase measurement of heterodyne interferometers, with particular focus on the LISA space mission and noise modeling for its precursor, LISA ...

Advances in the development of gamma-ray spectrometers have resulted in devices that are ideal for use in conjunction with the increasingly reliable systems of autonomously flying uncrewed aerial vehicles (UAVs) that have ...

Atom interferometers have gained attention in both fundamental physics research and practical applications thanks to their high accuracy. Improving them is a widespread area of research and generating highly phase stabilized ...

Die Laser Interferometer Space Antenna (LISA) ist eine Mission der europäischen Weltraumagentur (ESA) zur Detektion von Gravitationswellen im Frequenzbereich zwischen 10^-4 Hz und 1 Hz. Gravitationswellen induzieren relative ...

Modern physics is challenged by existential questions about the most fundamental interactions of matter. While three of the four known fundamental forces are modeled in the grand unified theory [1], gravity seems to be ...

This thesis presents the development and characterisation of an optomechanical system (OMS) with the aim to be part of an all-optical coherent quantum noise cancellation scheme (CQNC), as proposed by Tsang & Caves in ...

In light pulse atom interferometry wave packets are spatially separated and recombined in a coherent manner by interacting with laser pulses. Typically, two photon transitions are used to perform Rabi oscillations between ...

The GRACE Follow-On (GRACE-FO) satellite mission was launched in May 2018. It continues the time series of monthly estimates of the Earth’s gravity field, started by its predecessor, the Gravity Recovery And Climate ...
