24 Sep 2020 | Abstract: | The quantum system under periodical modulation is the simplest path to
understand the quantum non-equilibrium system, because it can be well described
by the effective static Floquet Hamiltonian. Under the stroboscopic
measurement, the initial phase is usually irrelevant. However, if two
uncorrelated parameters are modulated, their relative phase can not be gauged
out, so that it can dramatically change physics. Here, we simultaneously
modulate the frequency of lattice laser and Rabi frequency in the optical
lattice clock (OLC) system. Thanks to ultra-high precision and ultra-stability
of OLC, the relative phase could be fine-tuned. As a smoking gun, we observed
the interference between two Floquet channels. At last, we discuss the relation
between effective Floquet Hamiltonian and 1-D topological insulator with high
winding numbers. Our experiment not only provides a direction for detecting the
phase effect, but also paves a way in simulating quantum topological phase in
OLC platform. | Source: | arXiv, 2009.11671 | Services: | Forum | Review | PDF | Favorites |
