Resumen

We study the (Formula presented) Duffin-Kemmer-Petiau equation for spin-1 bosons in a noncommutative phase space under a uniform magnetic field. By introducing an effective frequency that incorporates the magnetic interaction and noncommutative parameters, the energy spectrum is split into two regions separated by critical frequencies. These points mark a change in the spectral structure, while preserving the energy continuity. The corresponding magnetic response is derived analytically and exhibits discontinuities at the critical frequencies, providing a clear signature of the transition between the spectral regions. The results show how phase-space noncommutativity modifies both the spectrum and its magnetic response. Copyright
