Description
We show that Landau quantization in strongly magnetized two-flavor color-superconducting quark matter suppresses the conventional Fermi-surface contribution to the transverse Meissner response, allowing it to be controlled by the quantum geometry of the quasiparticle states. As a result, the transverse Meissner mass scales with the pairing gap, in contrast to the conventional chemical potential scaling in the magnetized color-flavor-locked (CFL) phase. In the strong-field limit, this quantum-geometric response becomes directly tied to the Chern number of the lowest Landau level. The reduced transverse Meissner mass generates an intermediate propagation speed for magnetic disturbances along field lines, between relativistic CFL modes and crustal Alfvenic dynamics, with potential implications for kHz quasi-periodic oscillations in magnetars.
