The ATTO-CM research network

The ATTO-CM - shorthand for attosecond charge migration - is a DOE-funded collaboration network between Louisiana State University (LSU) Physics and Chemistry departments, the Ohio State University (OSU) and University of Virginia (UVA). It is and integrated relationship between theory (LSU) and experiments (OSU and UVA) to study charge migration with high-harmonic generation and ionization spectroscopies. Charge migration is the coherent, correlation-driven, displacement of electrons in a molecule following a localized excitation or ionization. High-harmonic generation is the nonlinear up-conversion process where a coherent broadband electromagnetic radiation is emitted as a result of strong-field-matter interactions.
