“…For the case of the double brane, the correction also occurs at the scale of r ∼ 1/k, but it has a complex form because of the rich structure of the mass spectrum of the resonance KK modes. According the recent test of the gravitational inverse-square law, the usual Newtonian potential still holds down to a length scale at 59µm [68]. Therefore, the thickness of the brane, 1/k, should be much less than 59µm.…”

In this work, we investigate gravitational resonances in both single and double mimetic thick branes, which can provide a new way to detect the extra dimension. For the single brane model, we apply the relative probability proposed in [Phys. Rev. D. 80 (2009) 065019]. For the double brane model, we investigate the resonances quasi-localized on the double brane, on the sub-branes and between the sub-branes, respectively. To investigate the resonances quasi-localized on the double brane, we introduce two different definitions of the relative probability and find that the corresponding mass spectra of gravitational resonances are almost the same. For the gravitational resonances quasi-localized on subbranes and between the sub-branes, the influence of the distance between the two subbranes and the thickness of the sub-branes are analyzed and new features are found in both cases.

“…In addition to this possibility, they found that their model could describe the hierarchy between the Planck mass and the electroweak symmetry breaking scale in terms of the large size of the extra dimensions. Therefore testing general relativity and its Newtonian limit at short distances has become particularly important in light of recent theoretical developments [4][5][6][7][8][9][10][11][12][13].…”

Numbers of tabletop experiments have made efforts to detect large extra dimensions for the range from solar system to submillimeter system, but the direct evidence is still lacking. Here we present a scheme to test the gravitational law in 4+2 dimensions at microns by using cavity optomechanical method. We have investigated the probe spectrum for coupled quantum levitated oscillators in optical cavities. The results show that the spectral splitting can be obtained once the large extra dimensions present. Compare to the previous experiment, the sensitivity can be improved by the using of a specific geometry and a shield mirror to control and suppress the effect of the Casimir background. The weak frequency splitting can be optically read by the pump-probe scheme. Thus we can detect the gravitational deviation in the bulk based ADD model via spectroscopy without the isoelectronic technique.

“…In this paper, we focus on searching for LLI violation in pure-gravity sector for d = 6, which has been widely tested by short-range gravitational experiments, since the short-range experiments are better than other experiments to probe higher dimension coefficients with r-dependence. The best current limit for d = 6 is at 10 −9 m 2 [25], which is given by a combined analysis for lab-based on-ground experiments HUST-2011 [26], HUST-2015 [27], IU-2002 and IU-2012 [28]. Based on the experiment performed in our lab, the test of the gravitational inverse square law, we have proposed a simple scheme to greatly enlarge the LLI violation signal [29].…”

Local Lorentz invariance is an important component of General Relativity. Testing for Local Lorentz invariance can not only probe the foundation stone of General Relativity but also help to explore the unified theory for General Relativity and quantum mechanics. In this paper, we search the Local Lorentz invariance violation associated with operators of mass dimension d = 6 in the pure-gravity sector with short-range gravitational experiments. To enlarge the Local Lorentz invariance violation signal effectively, we design a new experiment in which the constraints of all fourteen violation coefficients may be improved by about one order of magnitude.
