Abstract We propose in this White Paper a concept for space experiment using cold atoms to search ultra-light dark matter, and detect gravitational waves the frequency range between most sensitive ranges of LISA terrestrial LIGO/Virgo/KAGRA/INDIGO experiments. This interdisciplinary experiment, called Atomic Experiment Dark Matter Gravity Exploration (AEDGE), will also complement other planned searches exploit synergies with wave detectors. give examples extended sensitivity matter offered...
We report on a compact and ruggedized setup for laser frequency stabilization employing Doppler-free spectroscopy of molecular iodine near 532 nm. Using 30 cm long cell in triple-pass configuration combination with noise-canceling detection residual amplitude modulation control, instability 6×10-15 at 1 s integration time Flicker noise floor below 3×10-15 times between 100 1000 was found. A specific assembly-integration technology applied the realization setup, ensuring high beam pointing...
Abstract Light‐pulse atom interferometry with ultra‐cold quantum gases is proposed and numerically benchmarked as a platform to test the modulo‐square hypothesis of Born's rule. The interferometric protocol based on combination double Bragg single Raman diffraction induce multipath interference in Bose–Einstein condensates (BECs) block selected interferometer paths, respectively. In contrast previous tests employing macroscopic material slits blocking masks, optical lattices provide high...
We present a compact and robust distributed-feedback diode laser system architecture for ultracold atom experiments with K41 Rb87 in mobile setup operating at the ZARM drop tower Bremen. Our withstands DC accelerations of up to 43 g operation only minor adjustments over several campaigns. Micro-integrated master-oscillator-power-amplifier modules conjunction miniaturized, free-space opto-mechanics are integrated on platform volume L. With control driver electronics, this features output...
We realized ultra-stable optical frequency references on elegant breadboard (EBB) and engineering model (EM) level utilizing Doppler-free spectroscopy of molecular iodine near 532nm. A stability about 1•10<sup>-14</sup> at an integration time 1 s below 5•10<sup>-15</sup> times between 10 100 was achieved. These values are comparable to the currently best laboratory setups. Both setups use a baseplate made glass material where components joint using specific assembly-integration...
