Overview

Analysis reveals T1 relaxation mechanisms and nuclear spin dynamics in the V$_B^{-1}$ defect in hBN, indicating potential for quantum technology.

Key Points

  • The study demonstrates how T1 relaxation mechanisms in the V$_B^-$ center are influenced by electron-nuclear interactions and temperature.
  • Results show that the proposed spin dynamics model accurately predicts T1 time at specific magnetic field strengths, particularly at 90 G.
  • By including the effects of nearest-neighbor nuclear spins, the model provides insights into nucleus-based spin technology developments.
  • This work establishes coupling dynamics as essential for understanding and leveraging spin relaxation in quantum sensing applications.
