Atomic Cluster Collisions Research Articles

Topical issue “Dynamics of systems on the nanoscale (2021)”

Exploration of the structure formation and dynamics of animate and inanimate matter on the nanometer scale is a highly interdisciplinary field of rapidly emerging research. It is relevant for various molecular and nanoscale systems of different origins and compositions and concerns numerous phenomena originating from physics, chemistry, biology, and materials science. This topical issue presents a collection of research papers devoted to different aspects of the Dynamics of Systems on the Nanoscale. Some of the contributions discuss specific applications of the research results in several modern and emerging technologies, such as controlled nanofabrication with charged particle beams or the design and practical realization of novel gamma-ray crystal-based light sources. Most works presented in this Topical Issue were reported at the joint Sixth International Conference “Dynamics of Systems on the Nanoscale” and the tenth International Symposium “Atomic Cluster Collisions” (DySoN–ISACC 2021), which were held in Santa Margherita Ligure, Italy, in October 2021.

Topical Issue on atomic cluster collisions

The rapidly emerging field of atomic cluster collisions attracts strong research interest of many experimental and theoretical groups worldwide. Being a highly interdisciplinary field, it has numerous links with atomic, molecular and optical physics, astrophysics, plasma physics, biophysics, physical chemistry, solid state physics and even molecular biology. This Topical Issue presents a state-of-the-art description of current research activities in the field of atomic cluster collisions and atomic cluster science. The contributions to this Issue represent experimental, theoretical and computational studies both at the fundamental level of elementary mechanisms and at a more applied level which is necessary in numerous applications of nano- and biotechnology, materials science and medicine.

Atomic cluster collisions: ISACC-2015 (7th International Symposium)*

The ISACC 2015 brought together nearly a hundred scientists in the field of atomic and molecular cluster physics from around the world. We deliver the Editorial of a topical issue compiling/presenting original research results from some of the participants on both experimental and theoretical studies involving research areas from small clusters to extended molecular systems in the field.

Atomic cluster collisions

Atomic cluster collisions are a field of rapidly emerging research interest by both experimentalists and theorists. The international symposium on atomic cluster collisions (ISSAC) is the premier forum to present cutting-edge research in this field. It was established in 2003 and the most recent conference was held in Berlin, Germany in July of 2011. This Topical Issue presents original research results from some of the participants, who attended this conference. This issues specifically focuses on two research areas, namely Clusters and Fullerenes in External Fields and Nanoscale Insights in Radiation Biodamage.

Slow cross-symmetry phase relaxation in complex collisions

We discuss the effect of slow phase relaxation and the spin off-diagonal S-matrix correlations on the cross-section energy oscillations and the time evolution of the highly excited intermediate systems formed in complex collisions. Such deformed intermediate complexes with strongly overlapping resonances can be formed in heavy-ion collisions, bimolecular chemical reactions, and atomic cluster collisions. The effects of quasiperiodic energy dependence of the cross sections, coherent rotation of the hyperdeformed similar or equal to(3 : 1) intermediate complex, Schrodinger cat states, and quantum-classical transition are studied for Mg-24 + Si-28 heavy-ion scattering.

International Symposium “Atomic Cluster Collisions: Fission, Fusion, Electron, Ion and Photon Impact”

This article is aimed to deliver a comment on the International Symposium “Atomic Cluster Collisions: fission, fusion, electron, ion and photon impact” (ISACC 2003, a Europhysics Conference) held in St. Petersburg, Russia, July 18–21, 2003 as a satellite meeting of the XXIII International Conference on Photonic, Electronic, and Atomic Collisions (ICPEAC 2003, Stockholm, Sweden, July 23–29, 2003). We accompany a report about the Symposium by a brief introduction to atomic cluster physics, the interdisciplinary field, which developed rather successfully during recent years. We also outline some of the important trends in the development of atomic cluster science, which were discussed at the Symposium.

Quantum-classical correspondence in microscopic and mesoscopic complex collisions

We propose a novel method to study quantum-classical correspondence in complex, e.g., heavy-ion, atomic, molecular, and atomic cluster collisions. The many-body rotating wave packets are formed spontaneously and their stability is due to the slow decoherence between highly excited strongly overlapping states of the intermediate complex. The phenomenon is illustrated by analyzing the ${}^{12}{\mathrm{C}+}^{24}\mathrm{Mg}$ collision. The significant deviations from the random-matrix theory are reproduced in terms of the macroscopically rotating molecule formed in this collision.
