Nutation dynamics and multifrequency resonance in a many-body seesaw

Understand

The multifrequency resonance has been widely explored in some of the single-particle models, in which the modulating Rabi model has been most widely investigated.

• It has been found that with the diagonal periodic modulation, a steady dynamics can be realized in some well-defined discrete frequencies.
• These frequencies are independent of the off-diagonal couplings.
• In this work, we generalize this physics to the many-body seesaw realized using the tilted Bose-Hubbard model.
