On the stability of a class of slowly varying systems
Journal of Inequalities and Applications, 2018 Slowly varying systems are common in physics and control engineering and thus stability analysis for those systems has drawn considerable attention in the literature. This paper uses the “frozen time approach” to derive Lyapunov inequality conditions for

Generalized Adiabatic Theorems: Quantum Systems Driven by Modulated Time-Varying Fields
PRX Quantum, 2021 We present generalized adiabatic theorems for closed and open quantum systems that can be applied to slow modulations of rapidly varying fields, such as oscillatory fields that occur in optical experiments and light-induced processes.

On Stability Radii of Slowly Time-Varying Systems [PDF]
, 2001 We consider robustness of exponential stability of time-varying linear systems with respect to structured dynamical nonlinear perturbations. Sufficient conditions in terms of L 2-stability are derived. It is shown that the infimum of the complex stability radii of a family of time-invariant linear systems provides a good estimate for the stability ...

Adiabatic Invariants in Stellar Dynamics: I. Basic concepts [PDF]
, 1994 The adiabatic criterion, widely used in astronomical dynamics, is based on the harmonic oscillator. It asserts that the change in action under a slowly varying perturbation is exponentially small.

From efficient symplectic exponentiation of matrices to symplectic integration of high-dimensional Hamiltonian systems with slowly varying quadratic stiff potentials [PDF]
, 2011 We present a multiscale integrator for Hamiltonian systems with slowly varying quadratic stiff potentials that uses coarse timesteps (analogous to what the impulse method uses for constant quadratic stiff potentials).

Gradient catastrophe of nonlinear photonic valley-Hall edge pulses
Physical Review Research, 2021 We derive nonlinear wave equations describing the propagation of slowly varying wave packets formed by topological valley-Hall edge states. We show that edge pulses break up even in the absence of spatial dispersion due to nonlinear self-steepening. Self-
