We establish new experiments to search for dark matter based on a model of a light scalar field with a dilaton-like coupling to the electromagnetic field, which is strongly motivated by superstring theory. We estimate the power of the photon signal in the process of a non-resonant scalar-photon transition and in a cavity resonator permeated by electric and magnetic fields. We show that existing cavity resonators employed in the experiments like ADMX have a low but non-vanishing sensitivity to the scalar-photon coupling. As a result, by re-purposing the results of the ADMX experiment, we find new limits on the scalar-photon coupling in the range of the scalar field masses from 2.7 to 4.2 µeV. We discuss possible modifications of this experiment, which enhance the sensitivity to the scalar field dark matter. We also propose a broadband experiment for scalar field dark matter searches based on a high-voltage capacitor. The estimated sensitivity of this experiment exceeds by nearly two orders in magnitude the sensitivity of the experiment based on molecular spectroscopy.

“…Also, g is the QCD gauge coupling and β(g) is the beta function. Such couplings can be searched for via the equivalence principle violations and/or fifth forces experiments [36][37][38][39][40][41][42], or oscillation of fundamental constants (for a review, see for example [43]; for proposals, see [26,[44][45][46][47][48][49][50][51][52][53]; and for experiments providing bounds on oscillations see [54][55][56][57][58][59][60][61][62][63][64][65]). Note that, one can also consider ALP/axion interaction with m q qq, where q = u, d denotes the light quarks; see e.g.…”

We highlight general issues associated with quality and naturalness problems in theories of light QCD-axions, axion-like particles, and relaxions. We show the presence of Planck-suppressed operators generically lead to scalar coupling of axions with the SM. We present a new class of Z4N QCD relaxion models that can address both the QCD relaxion CP problem as well as its quality problem. This new class of models also leads to interesting experimental signatures, which can be searched for at the precision frontier.

“…Beyond that, recent developments have pushed the reach of atomic and molecular spectroscopy to probe α em variations to frequencies as high as 100 MHz. We show the bounds dynamic decoupling (DD) [62], Cs transitions [63] (see also Ref. [64]) and transitions in I 2 molecules [65] in different shades of blue.…”

Time and space translation invariance, giving rise to energy and momentum conservation, are not only amongst the most fundamental but also the most generally accepted symmetry assumptions in physics. It is nevertheless prudent to put such assumptions to experimental and observational tests. In this note, we take the first step in this direction, specifying a simple periodic time dependence that violates time translation invariance in QED, and setting phenomenological constraints on it. In addition to observational and experimental constraints on time varying couplings, we focus on probes of violation of energy conservation such as spontaneous production of photon and electron pairs and the e → eγ process. We discuss similarities and differences to the discussion of time varying fundamental constants and to the case of a light bosonic dark matter field that usually also causes oscillating effects.
