Unsupervised learning for the systematic identification of nondispersive wave packets in driven helium
Juan M. Scarpetta, Gustavo A. Parra, Alejandro González-Melan +1
Nondispersive wave packets in driven helium are long-lived quantum states that follow classical resonant orbits without spreading. Their identification typically requires detailed…

Floquet-engineered nondispersive wave packets in helium under combined periodic and static fields
Alejandro González-Melan, John Fitzgerald León Ocampo, Javier Madroñero
We report the numerical observation of two-electron nondispersive wave packets in fully three-dimensional helium subjected to a linearly polarized monochromatic field. These locali…

On a Matrix Ensemble for Arbitrary Complex Quantum Systems
William E. Salazar, Juan Diego Urbina, Javier Madroñero
We present a comprehensive analytical study of a variation of the eigenvector ensemble initially proposed by Deutsch for the foundations of the Eigenstate Thermalization Hypothesis…
