One-Electron Quantum Cyclotron as a Milli-eV Dark-Photon Detector

Concept of Coherence in Neutrino and Antineutrino Scattering off Nuclei

“…The long absence of positive results 1 from a wide range of dark matter search experiments gave rise to a lot of new, sometimes exotic suggestions about both the possible composition of dark matter itself [12][13][14][15][16], its unusual properties [17][18][19][20][21][22][23][24], and about more sophisticated methods of its detection [25][26][27][28][29][30][31][32]. Nevertheless, due to its exceptional significance [6,10,[33][34][35], it seems somewhat untimely to bury in oblivion the traditional method of directly detecting massive weakly interacting dark-matter particles without critical analysis of fundamental assumptions and details accepted in this method.…”

Macroscopic quantum response to gravitational waves

“…In this letter, we propose the search for high frequency gravitational waves by using a one-electron quantum cyclotron, which can also be utilized for the dark photon dark matter search [22]. By recasting the reported dark count rate in a penning trap [22], we give upper bounds on gravitational waves at frequencies of O(100) GHz, which have not been searched for.…”

By recasting the reported dark count rate in a penning trap [22], we give upper bounds on gravitational waves at frequencies of O(100) GHz, which have not been searched for. Generically, signal rates of gravitational wave detection are suppressed by the ratio of the size of the detector and the wavelength of the gravitational wave, which is O(mm) in the case of 100 GHz wave.…”

“…However, it does not change the evaluation of the excitation of a one-electron quantum cyclotron by gravitational waves at least approximately, since the coherent state has a Gaussian distribution with a peak at |m| ∼ k ∼ 10 3 . Using the upper limit on the dark count rate per unit time, 4.33 × 10 −6 s −1 , obtained in [22], one can evaluate the sensitivity of a one-electron quantum cyclotron to a planner gravitational wave through the transition of (3.2a) and (3.2b),…”
