“…Since then, it remains the most compelling solution to the strong-CP problem in QCD and a well-motivated dark matter candidate [3][4][5][6] . Due to this, a host of ultrasensitive experiments have been conducted to search for axions and axion-like paricles (ALPs) [3,[7][8][9][10][11]. Since one main property of axion is that it can interact with nucleons [7,12], the axion-tonucleon interaction has been focused on by amounts of work (see reviews [13,14]).…”

In this paper we develop a quantum optical method to detect the axion-nucleon interaction. We ultilize a levitated optomechanical system consisting of a silica nanosphere and an optical cavity here. We translate the trapping positions of the nanosphere, resulting the shift of its resonance frequency, which can be determined from measuring the resulting resonance shift in the transmission spectrum. Furthermore, The frequency shift can be related to the additional forces due to two-axion exchange via substraction. Based on noise ananlysis, estimation and calculation, we set the stringent prospective constraints for the coupling constants of axion-neucleon interaction gan and gap. In the case of g 2 an = g 2 ap , our constraints are most stringent at an ultrawide axion mass range approximately from 10 −4 µeV to 10 eV .

Axion remains the most convincing solution to the strong-CP problem and a well-motivated dark matter candidate, causing the search for axions and axion-like particles(ALPs) to attract attention continually. The exchange of such particles may cause anomalous spin-dependent forces, inspiring many laboratory ALP searching experiments based on the detection of macroscopic monopole-dipole interactions between polarized electrons/nucleons and unpolarized nucleons. Since there is no exact proof of the existence of these interactions, to detect them is still of great significance. In the present paper, we study the electron-neucleon monopole-dipole interaction with a new method, in which a hybrid spin-nanocantilever optomechanical system consisting of a nitrogen-vacancy(NV) center and a nanocantilever resonator is used. With a static magnetic field and a pump microwave beam and a probe microwave beam applied, a probe absorption spectrum could be obtained. Through specific peaks appearing in the spectrum, we can identify this monopole-dipole interaction. And we also provide a prospective constraint to constrain the interaction. Furthermore, because our method can also be applied to the detection of some other spin-dependent interactions, this work provides new ideas for the experimental searches of the anomalous spin-dependent interactions.

The Search for Ultralight Bosonic Dark Matter

View full text Add to dashboard Cite

The possible existence of exotic spin-dependent interactions with ranges from the subatomic scale to astrophysical scales has been of great theoretical interest for the last few decades. Typically, these exotic interactions are mediated by ultralight bosons with very weak coupling strength. If they indeed exist, such long-range interactions would indicate new physics beyond the Standard Model. A wide variety of experimental tests have been made to search for novel long-range spin-dependent interactions. Most experimental searches have focused on monopole-dipole or dipole-dipole interactions that could be induced by the exchange of ultralight bosons such as axions or axionlike particles. These ultralight bosons could also provide an answer to some of the most challenging problems in modern particle physics and astronomy: for example, the strong-CP problem in quantum chromodynamics (QCD), where C represents the charge conjugate symmetry and P represents the parity symmetry, and the explanation of dark matter and dark energy. In this chapter, we discuss the theoretical motivations as well as experimental searches for exotic spin-dependent interactions mediated by ultralight bosons in recent decades. We also introduce ongoing experimental efforts, such as Axion Resonant InterAction DetectioN Experiment (ARIADNE) and the QUest for AXion (QUAX)-gsgp experiment. The high sensitivities of these tests will allow vast expansion of the discovery potential for exotic spin-dependent interactions.
