Continuous-time quantum harmonic oscillator state engineering
Published 2023-01-01“…We show the time evolution for these systems with continuous differentiable time-dependent parameters in terms of the three basic operations provided by its underlying symmetry, rotation, displacement, and squeezing, using a Lie algebraic approach. Our factorization of the dynamics allows for the intuitive construction of protocols for state engineering, for example, creating and removing displacement and squeezing, as well as their combinations, optimizing squeezing, or more complex protocols that work for slow and fast rates of change in the oscillator parameters.…”

Abelian extensions of Lie triple systems with derivations
Published 2022-03-01“…. $ We first construct the third-order cohomology classes by derivations of $ A $ and $ \mathfrak{L}, $ then obtain a Lie algebra $ G_{\theta_A} $ with a representation $ \Phi $ on $ H^3(\mathfrak{L}, A), $ where $ \theta_A $ is given by an abelian extension $ 0\longrightarrow A\longrightarrow {\tilde {\mathfrak{L}}} \xrightarrow{\pi} \mathfrak{L}\longrightarrow 0. $ We study obstruction classes for extensibility of derivations of $ A $ and $ \mathfrak{L} $ to those of $ \tilde{\mathfrak{L}}. $ An application of $ \Phi $ is discussed.…”
