These results are an important step towards quantum tests of UFF in space and will allow scientists to investigate aspects of few-body physics, quantum chemistry and fundamental physics in new regimes without the perturbing asymmetry of gravity.īecker, D. ![]() Operating a single laser at a ‘magic wavelength’ at which Rabi rates of simultaneously applied Bragg pulses are equal, we have further achieved the first spaceborne demonstration of simultaneous atom interferometry with two atomic species ( 87Rb and 41K). Here, using upgraded hardware of the multiuser Cold Atom Lab (CAL) instrument aboard the International Space Station (ISS), we report, to our knowledge, the first simultaneous production of a dual-species BEC in space (formed from 87Rb and 41K), observation of interspecies interactions, as well as the production of 39K ultracold gases. In space, cooling the elements needed to explore the rich physics of strong interactions or perform quantum tests of the UFF has remained elusive. Terrestrial quantum sensors interfering the superposition of two ultracold atomic isotopes have tested the universality of free fall (UFF), a core tenet of Einstein’s classical gravitational theory, at the 10 −12 level 4. On Earth, these devices have produced macroscopic quantum phenomena such as Bose–Einstein condensates (BECs), superfluidity, and strongly interacting quantum gases 3. Ultracold temperatures amplify quantum effects, whereas free fall allows further cooling and longer interactions time with gravity-the final force without a quantum description. ![]() The capability to reach ultracold atomic temperatures in compact instruments has recently been extended into space 1, 2.

I noticed, that I need to use around 75-80% of volume if I want to have some "more sound", is this mean that this amplifier has not enough power for these speakers? I am connecting 1 speaker to each channel (in to total 5 speakers to 5 channels). Thank you very much for your replay Arno. ![]() High instantaneous-current capability (HCC): ☒5 amps Input sensitivity/impedance: 200mV/47k ohm Multichannel power: 75W per channel, two channels driven 6 ohms, 20Hz – 20kHz, <0.1% THD 100W per channel, two channels driven 6 ohms, 1kHz, <1% THD Nominal Impedance 8 Ω (transformer bypassed) Maximum SPL 1 m 103 dB SPL (109 dB SPL peak) Long-Term Power Handling 40 W (160 W peak) Recommended High-Pass Filter 70 Hz high-pass filter Can I use amplifier Onkyo TX-NR686 to connect these speakers?
