“…BECs have already been created in space, both in sounding rockets 36 and on the ISS 47 . Ultracold atomic bubbles have recently been observed in microgravity 48 . Furthermore, there are already plans for a second-generation device with many new capabilities to be operated on the ISS within a few years 49 .…”

Space-based research can provide a major leap forward in the study of key open questions in the fundamental physics domain. They include the validity of Einstein’s Equivalence principle, the origin and the nature of dark matter and dark energy, decoherence and collapse models in quantum mechanics, and the physics of quantum many-body systems. Cold-atom sensors and quantum technologies have drastically changed the approach to precision measurements. Atomic clocks and atom interferometers as well as classical and quantum links can be used to measure tiny variations of the space-time metric, elusive accelerations, and faint forces to test our knowledge of the physical laws ruling the Universe. In space, such instruments can benefit from unique conditions that allow improving both their precision and the signal to be measured. In this paper, we discuss the scientific priorities of a space-based research program in fundamental physics.

Progress in understanding quantum systems has been driven by the exploration of the geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom Laboratory (CAL) aboard the International Space Station has enabled the study of ultracold atomic bubbles, a terrestrially-inaccessible topology. Proof-of-principle bubble experiments have been performed on CAL with an rf-dressing technique; an alternate technique (dual-species interaction-driven bubbles) has also been proposed. Both techniques can drive discovery in the next decade of fundamental physics research in microgravity.

“…In order to fit the usual bubble trap geometry experiments [4][5][6][7][8][9][11][12][13][14][15][16][17][18][19], let us consider the finite factor of our potential in a generalized form as…”

“…Unfortunately, there are various technical difficulties in creating bubble trap experiments among which is the gravitational sag, i.e., the sinking of the BEC atoms into the bottom of the trap. With the current developments, it is possible to escape this problem working with microgravity either with free-falling experiments on earth-based laboratories [11,12] or space-based in the International Space Station with the Cold Atom Laboratory (CAL) [13][14][15][16][17][18][19]. Up until today, the usual microgravity [20] seems to be the best solution for confining atomic gases into shells in order to study its properties, but some new alternatives such as gravity compensation mechanisms are arising [21,22].…”

Within the many different models that appeared with the use of cold atoms to design BECs the bubble trap shaped potential has been of great interest. For the anisotropic bubble trap physics in the thin-shell limit the relationship between the physical parameters and the resulting manifold geometry is yet to be fully understood. In this paper, we work towards this goal showing how the parameters of the system must be manipulated in order to allow for a non-collapsing thin-shell limit. In such a limit, a dimensional compactification takes place thus leading to an effective 2D Hamiltonian which relates to up-to-date bubble trap experiments. At last, our Hamiltonian is pertubatively solved for some particular cases as applications of our theory.
