## Description

- description: Dynamic nuclear polarization (DNP) using the boron vacancy (V−B) in
    hexagonal boron nitride (hBN) has gained increasing attention. Understanding this
    DNP requires systematically investigating the optically detected magnetic resonance
    (ODMR) spectra and developing a model that quantitatively describes its behavior.
    Here, we measure the ODMR spectra of V−B in h10B15N across a wide range of magnetic
    fields, including the ground state level anti-crossing (GSLAC), and compare them
    with the results of the Lindblad-based simulation that considers a single electron
    spin and three neighboring 15N nuclear spins. We find the nuclear spin polarization
    estimated from the Lorentzian fitting of the ODMR spectra consistent with the
    simulation. Furthermore, our simulation successfully reproduces the experimentally
    obtained ODMR spectra, including the vicinity of GSLAC. By comparing these results
    in detail, we show that the conventional method of estimating polarization is
    qualitative but not quantitative. Finally, we show that symmetry-induced mechanisms
    of V−B limit the maximum polarization. Our study is an essential step toward a
    quantitative understanding of DNP using defects in hBN, and it paves the way for
    its quantum applications.
