Properties of Spin and Orbital Angular Momenta of Light
Arvind, S. Chaturvedi, N. Mukunda
This paper analyzes the algebraic and physical properties of the spin and orbital angular momenta of light in the quantum mechanical framework. The consequences of the fact that th…
Symplectic group methods and the Arthurs Kelly model of measurement in quantum mechanics
Arvind, S. Chaturvedi, N. Mukunda
We study the use of methods based on the real symplectic groups in the analysis of the Arthurs-Kelly model of proposed simultaneous measurements of position an…
Geometric phases for finite-dimensional systems -- the roles of Bargmann Invariants, Null Phase Curves and the Schwinger Majorana SU(2) framework
K S Akhilesh, Arvind, S Chaturvedi +2
We present a study of the properties of Bargmann Invariants (BI) and Null Phase Curves (NPC) in the theory of the geometric phase for finite dimensional systems. A recent suggestio…
Geometric Phase as the Key to Interference in Phase Space : Integral Representations for States and Matrix Elements
Mayukh N. Khan, S. Chaturvedi, N. Mukunda +1
We apply geometric phase ideas to coherent states to shed light on interference phenomenon in the phase space description of continuous variable Cartesian quantum systems. In contr…
On `orbital' and `spin' angular momentum of light in classical and quantum theories -- a general framework
Arvind, Subhash Chaturvedi, N. Mukunda
We develop a general framework to analyze the two important and much discussed questions concerning (a) `orbital' and `spin' angular momentum carried by light and (b) the paraxial…
Entanglement and Complete Positivity: Relevance and Manifestations in Classical Scalar Wave Optics
Arvind, S. Chaturvedi, N. Mukunda
Entanglement of states and Complete Positivity of maps are concepts that have achieved physical importance with the recent growth of quantum information science. They are however m…
