heal.abstract	We propose the existence of a macroscopic quantum phenomenon induced by a magnetic field in unconventional superconductors. It corresponds to the noninteger quantization of the superfluid density in a superconductor with gap nodes due to the generation of confined field-induced density waves (CFIDW) over a portion of the Fermi surface (FS). The Landau numbers L are not sufficient to index these macroscopic quantum states and new quantum numbers ζ must be added. Distinct qualitative implications of this L,ζ quantization are evident in a number of puzzling experiments in high- Tc cuprates including the plateaus behavior in the field profile of thermal conductivity, field-induced magnetic moments, charge textures around the vortices, and field-induced vortex-solid to cascade vortex glass transitions. © 2005 The American Physical Society.	en
