2 Jul 2020 | | Abstract: | Floquet engineering is a powerful tool to customize quantum states and
Hamiltonians via time-periodic fields. In this manuscript, we periodically
modulate the lattice potential of a $^{87}$Sr optical clock. Different from
previous works where the external (spatial) single-particle energies are
manipulated, we target the internal (atomic) degrees of freedom and engineer
the optical clock transition. We shape Floquet quasi-energies and measure their
resonance profiles with Rabi spectroscopy. We provide the spectroscopic
sensitivity of each band by measuring the Fisher information and show that this
is not depleted by the Floquet dynamical modulation. The demonstration that the
internal degrees of freedom can be selectively engineered by manipulating the
external degrees of freedom inaugurates a novel device for metrology, sensing
and quantum technologies. | | Source: | arXiv, 2007.0851 | | Services: | Forum | Review | PDF | Favorites | |
