“…In principle, according to the scale invariance and conformal invariance, the lower bound of d U ≥ 1 is imposed by the unitarity condition [3,45]. Our adopted range was originally introduced by Georgi in one of the seminal works on unparticle physics [2] and commonly used in relevant investigations on unparticle phenomenology later [19,[35][36][37][38][39].…”

“…[36] estimated the limits on the long-range interactions induced by vector unparticle exchange. Similarly, the bounds on such interactions have been obtained from geodetic and frame-dragging measurements by considering the vector unparticle coupling to the electronic (leptonic) and the nucleonic (baryonic) currents [39]. Here, assuming the deviation of the ISL originates from the unparicle-mediated VV interaction between nucleons (N-N), or electrons (e-e), or JHEP01(2024)083 nucleon and electron (N-e), the data in ref.…”

“…Liao and Liu [19] first proposed the idea of unparticle-mediated long-range interactions, using experimental data on the long-range spin-dependent interaction of electrons to constrain the couplings of unparticles to electrons. It was also noted that unparticles could mediate spin-independent long-range interactions, which might modify the inverse-square law (ISL) of gravity [35][36][37], contribute to the ground-state energy of the hydrogen atom [38], and influence the measurement of spacetime curvature near Earth [39]. The possibility of longrange interaction between neutrinos from unparticle exchange was also explored in solar…”

The potential discovery of unparticles could have far-reaching implications for particle physics and cosmology. For over a decade, high-energy physicists have extensively studied the effects of unparticles. In this study, we derive six types of nonrelativistic potentials between fermions induced by unparticle exchange in coordinate space. We consider all possible combinations of scalar, pseudo-scalar, vector, and axial-vector couplings to explore the full range of possibilities. Previous studies have only examined scalar-scalar (SS), pseudoscalar-pseudoscalar (PP), vector-vector (VV), and axial-axial-vector (AA) type interactions, which are all parity even. We propose SP and VA interactions to extend our understanding of unparticle physics, noting that parity conservation is not always guaranteed in modern physics. We explore the possibilities of detecting unparticles through the long-range interactions they may mediate with ordinary matter. Dedicated experiments using precision measurement methods can be employed to search for such interactions. We discuss the properties of these potentials and estimate constraints on their coupling constants based on existing experimental data. Our findings indicate that for some particular values of the scaling dimension $$ {d}_{\mathcal{U}} $$ d U , the coupling between scalar or vector unparticles and fermions is constrained by several orders of magnitude more tightly than the previous limits. The underlying reason for this improvement is analyzed. Limits are also set on the newly proposed SP and VA interactions for continuous $$ {d}_{\mathcal{U}} $$ d U values, allowing the exploration of the $$ {d}_{\mathcal{U}} $$ d U dependence of the constraints. It turns out that the bounds exhibit an exponential decay trend with the increasing $$ {d}_{\mathcal{U}} $$ d U .

“…Gravitational Waves (GWs) observed by LIGO/Virgo put bounds on ultralight DM as well [13,14]. Several tests of gravity in the solar system scale obtain interesting constraints on UVDM and USDM [15][16][17][18][19][20][21][22][23][24]. They can also be probed from the neutrino oscillation experiments [25][26][27].…”

The interaction of neutrinos with ultralight scalar and vector dark matter backgrounds induce a modification of the neutrino dispersion relation. The effects of this modification are reviewed in the framework of asymmetric emission of neutrinos from the supernova core, and, in turn, of pulsar kicks. We consider the neutrino oscillations, focusing in particular to active-sterile conversion. The ultralight dark matter induced neutrino dispersion relation contains a term of the form δ Ω · p̂, where δ Ω is related to the ultralight dark matter field and p̂ is the unit vector along the direction of neutrino momentum. The relative orientation of p with respect to δ Ω affects the mechanism for the generation of the observed pulsar velocities. We obtain the resonance condition for the active-sterile neutrino oscillation in ultralight dark matter background and calculate the star parameters in the resonance surface so that both ultralight scalar and vector dark matter backgrounds can explain the observed pulsar kicks. The asymmetric emission of neutrinos in presence of ultralight dark matter background results gravitational memory signal which can be probed from the future gravitational wave detectors such as adLIGO (advanced LIGO), adVIRGO (advanced VIRGO), DECIGO (DECi-hertz Interferometer Gravitational wave Observatory), BBO (Big Bang Observer), and ET (Einstein Telescope). We also establish a relation between the ultralight dark matter parameters and the Lorentz and CPT invariance violation parameters.

“…The "fuzzy", wavelike nature of such particles can also affect structure formation [15][16][17]. An important probe of ultralight dark matter arises in precision tests using atomic clocks and other quantum technologies [18][19][20][21][22][23][24][25][26][27][28], which are complementary to interesting astrophysical [29][30][31][32][33][34][35], cosmological [36][37][38][39][40], planetary and space probes [41][42][43][44][45].…”

Direct detection of ultralight dark matter bound to the Sun with space quantum sensors

Recent advances in quantum sensors, including atomic clocks, enable searches for a broad range of dark matter candidates. The question of the dark matter distribution in the Solar system critically affects the reach of dark matter direct detection experiments. Partly motivated by the NASA Deep Space Atomic Clock (DSAC) and the Parker Solar Probe (PSP), we show that space quantum sensors present new opportunities for ultralight dark matter searches, especially for dark matter states bound to the Sun. We show that space quantum sensors can probe unexplored parameter space of ultralight dark matter, covering theoretical relaxion targets motivated by naturalness and Higgs mixing. If an atomic clock were able to make measurements on the interior of the solar system, it could probe this highly sensitive region directly and set very strong constraints on the existence of such a bound-state halo in our solar system. We present sensitivity projections for space-based probes of ultralight dark matter which couples to electron, photon, and gluon fields, based on current and future atomic, molecular, and nuclear clocks.
