Quantum Collisions and Confinement of Atomic and Molecular Species, and Photons

This book comprises selected peer-reviewed papers presented at the 7th Topical Conference of the Indian Society of Atomic and Molecular Physics, jointly held at IISER Tirupati and IIT Tirupati, India. The contributions address current topics of interest in atomic and molecular physics, both from the theoretical and experimental perspective. The major focus areas include quantum collisions, spectroscopy of atomic and molecular clusters, photoionization, Wigner time delay in collisions, laser cooling, Bose-Einstein condensates, atomic clocks, quantum computing, and trapping and manipulation of quantum systems. The book also discusses emerging topics such as ultrafast quantum processes including those at the attosecond time-scale. This book will prove to be a valuable reference for students and researchers working in the field of atomic and molecular physics.

Presents latest research findings related to atomic and molecular physics Features contributions from experts across the globe on topics like quantum collisions, quantum confinement, photoionization, Wigner time delay, and Bose-Einstein condensates Provides insight into emerging areas such as ultrafast control of quantum processes at the attosecond scale
