Welcome from the Chair
Dear Colleagues,
Following the success of the 1st International Online Conference on Atoms (IOCAT2026), it is my pleasure to welcome you to the 2nd International Online Conference on Atoms (IOCAT2027), which will take place online from 27 to 29 January 2027. The conference is organized by the MDPI open access journal Atoms (ISSN: 2218-2004; Impact Factor: 1.5).
The first edition of IOCAT demonstrated the strong interest of the community in an international forum dedicated to atomic physics and its applications. Building on this success, the 2027 edition will extend over three days, allowing for a broader scientific program and more opportunities for discussion and interaction among participants.
IOCAT2027 aims to bring together researchers working in the diverse areas of atomic physics and related fields, providing a platform to present recent advances in and exchange ideas on both theoretical and experimental developments.
The conference will feature the following sessions:
S1. Atomic structure and spectroscopy: theory and experiment;
S2. Atomic collisions and strong field processes;
S3. Atomic data for astrophysics and laboratory plasmas;
S4. Cold atoms, quantum control and quantum technologies;
S5. Computational and AI methods in atomic physics;
S6. Fundamental tests and precision measurements with atoms.
These topics reflect the breadth and vitality of modern atomic physics, from fundamental studies of atomic structure and interactions to emerging applications in quantum technologies, astrophysics, and precision measurements.
As an online international conference, IOCAT2027 offers researchers from around the world the opportunity to participate and to exchange ideas without the need for travel, enabling a wide and diverse participation.
I would like to thank all members of the scientific and organizing committees for their efforts in preparing this conference, as well as all speakers and participants for contributing to its success.
I look forward to welcoming you to IOCAT2027 for three days of stimulating scientific exchange.
Kind regards,
Prof. Dr. Pascal Quinet

S2. Atomic collisions and strong field processes.
He received his PhD in Atomic Physics, specializing in beam-foil spectroscopy, under the guidance of Prof. Indrek Martinson in 1988. He remained at Lund until accepting a full professorship at the EBIT Laboratory of Fudan University in Shanghai, China. There, he spent more than 14 years studying the spectroscopy of highly charged ions using Electron Beam Ion Traps as a light source. One of his notable contributions to spectroscopy was the co-discovery of a magnetic-sensitive transition in the spectrum of Fe X. The resulting spectral line is sensitive to the magnetic field of the solar corona and has provided a valuable diagnostic tool for solar physics.

S2. Atomic collisions and strong field processes.
Vincenzo Laporta earned a master’s degree in physics in 2003 and a Ph.D. in High-Energy Physics in 2007 from the University of Bari. Following the completion of his doctoral studies, he pursued postdoctoral research in France, working at the École Polytechnique, the Institut de Physique de Lyon, and the University of Le Havre, where he obtained the Habilitation à Diriger des Recherches (HDR). He also held research positions at University College London and in the United States. In 2018, he was appointed Research Scientist at the National Research Council of Italy and is currently based at the University of Bari. His research focuses on molecular dynamics and the modeling of systems under thermodynamic non-equilibrium conditions. In particular, he employs ab initio quantum chemistry methods to investigate electron-induced processes in molecules and molecular ions. His work addresses phenomena such as molecular dissociation, vibrational excitation, and ionization. The resulting theoretical and computational models have applications across a broad range of fields, including plasma-assisted combustion, atmospheric entry of spacecraft into planetary environments, controlled nuclear fusion, the physics and chemistry of the interstellar medium, and the prebiotic synthesis of biomolecules.
