Controlling the entangled F???F state via a double resonance experiment employing RF pulses.

Abstract: Beyond conventional ?SR experiments, where control over the local interactions between muons and surrounding spins is lacking, we aim to experimentally manipulate these interactions, following muon implantation, in muon-coupled systems using advanced RF techniques. We propose a double resonance experiment to control the entangled F???F state in LaF3. By selectively altering the spin states of either the muon or fluorine with specific pulsing sequences, we seek to investigate how the local environment influences the F???F system. With the appropriate circuitry and pulse designs in place, we will begin with zero-field, zero-excitation experiments, and then implement optimized single and double pulses, transitioning from zero-field to higher longitudinal fields, in order to target possible transitions in various spin state populations and compare the results with our simulations of the F???F complex. We also plan to use a Hahn echo sequence to investigate the modulation of the spin echo envelope which results from the muon-fluorine coupling.
