RT Journal Article T1 Modulated Continuous Wave Control for Energy-Efficient Electron-Nuclear Spin Coupling A1 Casanova, Jorge A1 Torrontegui Muñoz, Erik A1 Plenio, Martin B. A1 García-Ripoll, Juan José A1 Solano, Enrique AB We develop energy efficient, continuous microwave schemes to couple electron and nuclear spins, using phase or amplitude modulation to bridge their frequency difference. These controls have promising applications in biological systems, where microwave power should be limited, as well as in situations with high Larmor frequencies due to large magnetic fields and nuclear magnetic moments. These include nanoscale NMR where high magnetic fields achieves enhanced thermal nuclear polarization and larger chemical shifts. Our controls are also suitable for quantum information processors and nuclear polarization schemes.
