“…Testing the existence of branes or extra dimensions is therefore becoming a fundamental challenge. Such evidences are expected to be obtained through high energy collisions [2][3][4], but it has been also demonstrated that some detectable effects could also be observed at low energy [2,3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] . This is the topic of the present paper.…”

Recent theoretical works have shown that matter swapping between two parallel braneworlds could occur under the influence of magnetic vector potentials. In our visible world, galactic magnetism possibly produces a huge magnetic potential. As a consequence, this paper discusses the possibility to observe neutron disappearance into another braneworld in certain circumstances. The setup under consideration involves stored ultracold neutrons − in a vessel − which should exhibit a non-zero probability p to disappear into an invisible brane at each wall collision. An upper limit of p is assessed based on available experimental results. This value is then used to constrain the parameters of the theoretical model. Possible improvements of the experiments are discussed, including enhanced stimulated swapping by artificial means.

“…We have used static AFM techniques to measure the mentioned force between the sphere and a metal coated plate [7]. The dynamical AFM (DAFM) technique which measures the force gradient between the sphere and substrate is expected to be more sensitive [9][10][11][12][13]. More sensitivity implies higher precision in the Casimir force measurements at the explored sphere to plate distances.…”

“…Many experimental groups have utilized this recipe to measure the spin of small ensembles of electrons or nuclei [12]. Researchers have also used these types of cantilevers to make noncontact friction measurements [11], and non-Newtonian force measurements [13]. These experiments were mostly done with cantilevers fabricated in a traditional nanofabrication facility.…”

“…As mentioned above, to measure the Casimir force we use the sphere-plate geometry, where we attach a Cr/Au-coated sphere to a single crystal silicon (Si) cantilever, and measure the force between the sphere and a Cr/Au plate. The sensitive cantilevers, used by others [10][11][12][13] might not be suitable for our experiment, because the metal coated sphere is large and massive. The cantilevers might break or the internal stresses induced will decrease force sensitivity.…”

Generation and monitoring of directed neutrino beams using electron-capturedecay sources C. Abstract. Higher sensitivity cantilevers will lead to exploration of new phenomena in the Casimir effect. We have used focused ion beam milling to reduce the width of a commercial single crystal, rectangular-shaped silicon cantilevers with a massive Cr/Au-coated-hollow sphere attached at their free end. Theoretically these milled and modified cantilevers should have better Casimir force sensitivity than their non-milled counterparts. In this preliminary report however only 1 out of 4 modified cantilevers were found to have a higher force sensitivity. Future studies will be needed to determine the general applicability of focused ion beam milling for force sensitivity improvements in comparison to the complete nanofabrication of cantilevers.

“…Traditional experiments, following the pioneering measurements of Cavendish in 1798 [125], now use a variety of approaches from superconducting gravity gradiometers [126] and microcantilevers [127] to planar oscillators [128] and torsion balance experiments [129]. However, in scaling down experiments to probe ever decreasing length scales a new, fundamental problem arises.…”

In recent years, bright soliton-like structures composed of gaseous Bose-Einstein condensates have been generated at ultracold temperature. The experimental capacity to precisely engineer the nonlinearity and potential landscape experienced by these solitary waves offers an attractive platform for fundamental study of solitonic structures. The presence of three spatial dimensions and trapping implies that these are strictly distinct objects to the true soliton solutions. Working within the zero-temperature mean-field description, we explore the solutions and stability of bright solitary waves, as well as their interactions. Emphasis is placed on elucidating their similarities and differences to the true bright soliton. The rich behaviour introduced in the bright solitary waves includes the collapse instability and symmetry-breaking collisions. We review the experimental formation and observation of bright solitary matter waves to date, and compare to theoretical predictions. Finally we discuss the current state-of-the-art of this area, including beyond-mean-field descriptions, exotic bright solitary waves, and proposals to exploit bright solitary waves in interferometry and as surface probes.
