quantum dynamics in the kicked top model and its generalizations

POSTER

Abstract

The kicked top model has been extensively studied for exploring classical and quantum chaos. Typically, the normalized quadratic interaction, where the strength inversely scales with the size of the system, is considered to avoid the divergent energy density. Here, we show that such a constraint can be relaxed by considering an alternative means of realizing the kicked top model and its generalizations. As a result, new quantum chaotic behaviors emerge and enable precision measurements beyond the standard quantum limit.
