  "abstract": "We establish the relation between optical condensate spectral weight and static magnetic screening in a proposed effective theory of charged bosonic condensates with an additional diamagnetic coupling. Starting from an explicit Ginzburg–Landau functional, we derive both the London equation and the transverse low-frequency conductivity. At fixed condensate parameter q 2 n s / m ∗ , the modified coupling doubles the inverse-square magnetic screening length and the optical condensate weight, giving λ mag = λ stiff = λ L / 2 , where λ L − 2 = μ 0 q 2 n s / m ∗ . Their ratio is therefore unity in both the standard and modified local theories: it tests consistency between measurement methods but cannot distinguish the couplings. A structured comparison of published results for Nb, Pb, YBCO, MgB 2 , and Ba(Fe,Co) 2 As 2 identifies the roles of sample matching, absolute calibration, nonlocality, and spectral-weight extraction. We formulate the requirements for a discriminating absolute-response experiment and discuss a complementary single-particle spectral prediction. The analysis separates experimentally accessible consistency checks from tests requiring independent information about condensate parameters or a different observable.",
