Coherent control of matter waves using mechanical action of electromagnetic field displays quantum duality at work. Deflecting, focussing and trapping the matter wave or de Broglie wave using optical fields lead us to develop tools to manipulate the matter waves. The emerging field provides a playground to study the newer effects of quantum coherence and quantum interference. The expansion of this area in last three decades has enabled us to store atoms and cool them to temperatures as low as micro kelvin scale and beyond, leading to experimental realization of Bose-Einstein condensation (BEC) and of Fermi degeneracy in ultra-cold. With a focus on graduate students and young researchers, this book discusses the topics that lay the foundation stones of interaction of ultra-cold atoms with optical potentials.
Key Features:
- It is developed keeping in view latest experimental advancements
- It puts light on newer theoretical advancement
- Explains the text though definitions, and useful diagrams
- Provides necessary examples and problems for the students
- It is simple in language, slender, and not voluminous

O autorze
Dr. Farhan Saif served as the chairman, department of Electronics, Quaid-i-Azam University (QAU, Islamabad) and as the Founding Head of Department of Physics, National University of Science and Technology. He obtained teaching and research experience at the University of Ulm, University of Arizona, University of Sao Paulo (UNESP), and University of Electro Communication, Tokyo. Dr. Saif has received doctorate degree from University of Ulm, Germany in 1998. He has been an Associate Member of the Abdus Salam International Centre for Theoretical Physics, Trieste, Italy. He served as a professor of department of Physics QAU from 2016 till 2018, and presently serving as a Tenured Professor of Electronics. Dr. Saif’s research areas include ultracold atoms and Bose-Einstein condensates in optical fields, quantum computation and quantum information, nano optomechanics, nano-devices, quantum optics and dynamical systems. Dr Saif is the principle investigator of Quantum Electronics Labs, QAU, where he has supervised twelve Ph D and 55 MPhil thesis. In recognition of his many pioneering contributions as a researcher and educator he has received numerous national and international awards. Dr Saif has collaborated with theorists and experimentalists alike in research institutions including University College London, Hunan Normal University, Turin Polytechnic university, College of William and Mary, Virginia, Abdelmalek Essaadi University Morocco, Tokyo University and the University of Electro-Communications.Dr Shinichi Watanabe worked as a Tenured Professor at the Department of Engineering Science, University of Electro-Communications (UEC Tokyo), Tokyo, Japan. Previously, he worked as a researcher of the CNRS at the Observatory of Paris at Meudon, France from 1981 till 1987. Dr Watanabe obtained his Ph D degree in 1982 at the University of Chicago, USA. Earlier, he completed his BSc in 1977 at Brown University, USA. He served as the Chairman, Department of Applied Physics and Chemistry at UEC Tokyo, and currently he is serving as Director of the International Education Center at the same university. Dr Watanabe’s research interests primarily concerns the dynamics of atoms and their interaction with light. He worked on the double ionization threshold law of the two-electron atom/ion, high-resolution continuum spectra of diamagnetic hydrogen-like atoms, hyperspherical adiabatic theory, Bose–Einstein condensation, ultra-cold molecular formation, and the dynamics of ultra-cold atoms in optical lattices. He ran a group working on Atomic, Molecular, and Optical (AMO) Physics, at the Department of Engineering Science at UEC Tokyo, and has supervised five Ph D and 33 MSc theses. Dr Watanabe has collaborated worldwide with researchers at Kansas State University, USA; the Observatory of Paris at Meudon, France; the University of Tennessee, Knoxville, USA; JILA at the University of Colorado at Boulder, USA; and Quaid-i-Azam University, Pakistan, among others.
