If dark matter with milli-charge bonded to ordinary matter existed, quantum effects should be observed
Bibliographic record
Abstract
Abstract We propose a quantum optomechanical method to probe the potential existence of dark matter particles possessing an infinitesimal electric charge, known as milli-charged particles (mCPs), when bound to ordinary matter. In our setup, a charged fused silica nanosphere (NS) is optically levitated within a Fabry–Perot cavity and subjected to an additional electrostatic field produced by a charged metallic ring. If mCPs exist and are embedded in the NS as relics of early Universe matter, their presence would generate a tiny but measurable deviation from a purely thermal output spectrum. Specifically, the output light from the cavity would exhibit quadrature squeezing even at room temperature, and the NS center-of-mass motion could become entangled with the optical field. These quantum effects are absent when there are no residual infinitesimal charges in the NS. We provide a theoretical framework for this proposal, including the system Hamiltonian and linearized quantum Langevin dynamics, and show how measurements of squeezing and entanglement in the cavity output can reveal the presence of bound mCPs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
